62-569: The GAF Jindivik is a radio-controlled target drone produced by the Australian Government Aircraft Factories (GAF). The name is from an Aboriginal Australian word meaning "the hunted one". Two manually-controlled prototypes, were built as the GAF Pika (Project C) as a proof of concept to test the aerodynamics, engine and radio control systems, serialled A92-1/2 , 'B-1/2'. The radio-controlled Jindivik

124-408: A Very pistol . The intention was to force any encroaching U-boat to dive; one aircraft would then remain in the vicinity while the other would search for a naval patrol vessel that could be led back to the spot. Because they were not radio equipped, each aircraft also carried a pair of homing pigeons in a wicker basket to call for help in case of a forced landing at sea. A 25-lb (11.5 kg) bomb

186-566: A Tiger Moth and intended to cut parachutists' canopies as they descended. Flight tests proved the idea, but it was not officially adopted. The Tiger Moth was also tested as a dispenser of Paris green rat poison for use against ground troops, with powder dispensers located under the wings. In the postwar climate, impressed Tiger Moths were restored to their former civilian operations and owners. Accordingly, large numbers of Tiger Moths were made available for sale to flying clubs and individuals. Relatively few new light aircraft being manufactured at

248-427: A heavy degree of designed-in differential operation (mostly deflecting up, hardly at all downwards) to avoid adverse yaw problems in normal flight. Most manoeuvres are started at about 90 to 110 knots, and it has a Velocity Never Exceeded (VNE) of 140 knots. It is important to lock the automatic slats (leading edge flaps) during aerobatic manoeuvres. There are two methods of landing. "Wheeler" landing involves pushing

310-408: A hopper to hold superphosphate for aerial topdressing. A large number were also used to deploy insecticide in the crop-sprayer role, for which several alternative arrangements, including perforated piping being installed underneath the mainplanes or the placement of rotary atomisers on the lower mainplane, were used. Royal Navy Tiger Moths used as target tugs and "air experience" machines became

372-609: A radio-control system in the rear cockpit to operate the controls using pneumatically driven servos . In total, 400 were built by de Havilland at Hatfield and a further 70 by Scottish Aviation . There were nearly 300 in service at the start of the Second World War. In December 1939, owing to a shortage of maritime patrol aircraft , six flights of Tiger Moths were operated by RAF Coastal Command for surveillance flights over coastal waters, known as "scarecrow patrols". The aircraft operated in pairs and were armed only with

434-594: A replica of a Fokker D.VII , while two aircraft resembled the Rumpler C.V to depict these types for the film. Several Tiger Moths were used in the crash scenes in The Great Waldo Pepper , standing in for the Curtiss JN-1 . Due to the popularity of the design and the rising cost of flyable examples, a number of replicas (scale and full-sized) have been designed for the homebuilder; these include

496-471: A suitable ab initio training aircraft. One of the main changes from the preceding Moth series was improved access to the front cockpit , since the training requirement specified that the front-seat occupant had to be able to escape easily, especially when wearing a parachute . Access to the front cockpit of the Moth's predecessors was restricted by the proximity of the aircraft's fuel tank, directly above

558-695: A total of 502 aircraft were produced. Examples for use in the United Kingdom were shipped by surface transport, and assembled and tested by Fairey Aviation at Hayes, Middlesex , and Manchester Airport . In 1997, the production line was re-opened to build another 15 for Britain. Since production began, the Jindivik has been used by the Royal Australian Air Force , the Royal Australian Navy 's Fleet Air Arm , and

620-676: Is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company . It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ab initio training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers . The Tiger Moth remained in service with

682-493: Is now an owners' association offering a mutual club and technical support. Geoffrey de Havilland, the company's owner and founder, had sought to produce a light aircraft superior to two of his previous designs, the de Havilland Humming Bird and de Havilland DH.51 . From earlier experience, de Havilland knew the difficulty and importance of correctly sizing such an aircraft to appeal to the civilian market, such as touring, trainer , flying club , and private aviation customers;

744-485: Is typically powered by a de Havilland Gipsy III 120 hp engine; later models are often fitted with more powerful models of this engine, while some have been re-engined by third-party companies. One characteristic of the Tiger Moth design is its differential aileron control setup. The ailerons (on the lower wing only) on a Tiger Moth are operated by an externally mounted circular bell crank, which lies flush with

806-416: Is uneventful, and it has a reasonable rate of climb. However full power should not be maintained for more than a minute to avoid damaging the engine. The Tiger Moth's biplane design makes it strong, and it is fully aerobatic. However it has ailerons only on its bottom wing, which makes its rate of roll relatively slow for a biplane; and, as stated previously, the ailerons on a Tiger Moth normally operate with

868-701: The Commonwealth were quickly impressed into their respective air forces to meet the wartime demand for trainer aircraft. The Tiger Moth became the primary trainer throughout the Commonwealth and elsewhere. It was the principal type used in the British Commonwealth Air Training Plan , where thousands of military pilots got their first taste of flight in a Tiger Moth. The RAF found the Tiger Moth's handling ideal for training fighter pilots. Generally docile and forgiving in

930-558: The Fisher R-80 Tiger Moth and the RagWing RW22 Tiger Moth . The Tiger Moth responds well to control inputs and is fairly easy to fly for a tail-dragger. Its big "parachute" wings are very forgiving, and it stalls at a speed as slow as 25 knots with power. Its stall and spin characteristics are benign. It has some adverse yaw and therefore requires rudder input during turns. The Tiger Moth exhibits

992-712: The Royal Air Force . The last Australian Jindiviks were taken out of service in the late 1990s and were replaced by the Kalkara . Most UK tests were conducted by the Royal Aircraft Establishment at their Llanbedr establishment and fired over the nearby Aberporth Airport test range in west Wales . In the UK, the drone was used in the development of the Bristol Bloodhound , English Electric Thunderbird , and Seaslug surface-to-air missiles, and

1054-404: The Royal Aircraft Establishment . Control was maintained through an autopilot that received radio commands from the ground, rather than direct flight by a ground controller. Eighteen commands could be issued to the autopilot with six further commands for the operation of other onboard equipment. The drone was launched via a self-steering trolley. At 110 knots (200 km/h; 130 mph), the drone

1116-516: The Tiger Moth . Improvements made on the Tiger Moth monoplane were incorporated into a military trainer variant of the DH.60 Moth, the DH.60T Moth – the T coming to stand for 'Tiger' in addition to 'Trainer'. The DH.60T Moth had several shortcomings, thus was subject to several alterations, such as the adoption of shortened interplane struts to raise the wingtips after insufficient ground clearance

1178-464: The de Havilland Firestreak air-to-air missile. Small numbers of the aircraft have also been operated by both Sweden, who used the Jindivik 2, and the United States.

1240-623: The Belgian-designed Stampe SV.4 aerobatic aircraft, which had a very similar design layout; both aircraft made use of a similar main landing gear configuration, a slightly sweepback wing, and an alike engine/cowling design. Several Tiger Moths were converted during the 1950s to a Coupe standard, which involved the installation of a sliding canopy over both crew positions, not unlike the Canadian-built Fleet Finch biplane trainers that had worked beside

1302-636: The Netherlands during the postwar era and used to equip the Dutch National Flying School at Ypenburg . These aircraft were required by the Dutch civil aviation authorities to be fitted with a larger dorsal fin, incorporating an extended forward fillet to the fin, to provide for additional area; this requirement was also extended to privately owned Tiger Moths in the Netherlands. The Tiger Moth might be confused at first glance with

1364-589: The PT-24, before being delivered onwards to the RCAF. Additional overseas manufacturing activity also occurred, most of which took place during wartime. de Havilland Australia assembled an initial batch of 20 aircraft from parts sent from the United Kingdom prior to embarking on their own major production campaign of the DH.82A, which resulted in a total of 1,070 Tiger Moths being constructed in Australia. In late 1940,

1426-652: The RAF until it was replaced by the de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is still occasionally used as a primary training aircraft, particularly for those pilots wanting to gain experience before moving on to other tailwheel aircraft. Many Tiger Moths are now employed by companies offering trial lesson experiences. The de Havilland Moth club, founded in 1975,

1488-586: The Sk.11' by AB Svenska Järnvägsverkstädernas Aeroplanavdelning , 91 were built in Portugal by OGMA , and another 38 in Norway by Kjeller Flyfabrikk (some sources say 37 so the first may have been assembled from a kit) in addition to a large number of aircraft that were assembled from kits shipped from the UK. The RAF ordered 35 dual-control Tiger Moth Is, which had the company designation DH.82. A subsequent order

1550-747: The Tiger Moth II, were delivered to the RAF; these aircraft adopted the de Havilland Gipsy Major engine, capable of generating 130 HP, and the use of plywood decking on the rear fuselage in place of fabric . Throughout the period 1934–1936, production activity was centred upon meeting the demand for military trainers, including several contracts having been placed by the RAF to Specification T.7/35, along with export orders by seven overseas operators. Civil examples were also being produced at this time, both for British private customers and to export customers in countries such as Ceylon , Greece , Lithuania , Rhodesia , Peru , and Switzerland . After 1936,

1612-528: The Tiger Moth in RCAF service as trainers in Canada during the type's wartime years. After the development of aerial topdressing in New Zealand, large numbers of ex- Royal New Zealand Air Force Tiger Moths built in that country and in the United Kingdom were converted into agricultural aircraft ; at the time, this was a pioneering use for aircraft. In this role, the front seat was commonly replaced with

1674-414: The Tiger Moth was made available to general flying clubs, production having been previously occupied by military customers. The type was used to replace older aircraft in the civilian trainer capacity, such as the older de Havilland Cirrus Moth and Gipsy Moth. By the start of the Second World War, the RAF had around 500 Tiger Moths in service. In addition, nearly all civilian-operated Tiger Moths throughout

1736-552: The Tiger Moth, using many of the main components of the former with a new plywood fuselage seating four people in an enclosed cabin; it was marketed as the de Havilland Fox Moth . Following the end of all manufacturing, third parties occasionally rebuilt Tiger Moths to a similar configuration to the Fox Moth, such as the Thruxton Jackaroo . In late 1934, 50 Tiger Moths of a more refined design, sometimes referred to as

1798-519: The UK for completion. Canadian-built Tiger Moths featured modifications to better suit the local climate, along with a reinforced tail wheel, hand-operated brakes (built by Bendix Corporation ), shorter undercarriage radius rods, and the legs of the main landing gear legs being raked forwards as a safeguard against tipping forwards during braking. In addition, the cockpit had a large sliding canopy fitted along with exhaust -based heating; various alternative undercarriage arrangements were also offered. By

1860-775: The United Kingdom, obsolete Royal Air Force and Royal Navy jet and propeller-powered aircraft (such as the Fairey Firefly , Gloster Meteor and de Havilland Sea Vixen used at RAE Llanbedr between the 1950s and 1990s) have also been modified into remote-controlled drones, but such modifications are costly. With a much larger budget, the U.S. military has been more likely to convert retired aircraft or older versions of still serving aircraft (e.g., QF-4 Phantom II and QF-16 Fighting Falcon ) into remotely piloted targets for US Air Force , US Navy and US Marine Corps use as Full-Scale Aerial Targets.

1922-459: The cockpit) and retractable undercarriage operated from a pneumatic reservoir. The remotely-piloted version, the Jindivik, followed the same basic form except that it had a single skid instead of an undercarriage and a dorsal air intake located where the Pika's cockpit was. The Jindivik Mk.1 was powered by an Armstrong Siddeley Adder (ASA.1) turbojet , which had been developed as a disposable engine for

1984-526: The contract for developing a target drone to Ministry of Supply specification E.7/48 . The specification called for an aircraft capable of a 15-minute sortie at 12,000 metres (40,000 ft). Development began in 1948, with the first flight of the Pika in 1950 and the first flight of the Jindivik Mk.1 in August 1952. The manually piloted prototype, known as the Pika, had side air intakes (to make room for

2046-427: The early 1970s. The Tiger Moth (and to a lesser extent, the similar Belgian Stampe-Vertongen SV.4 ) had been often used as a stand-in for rarer aircraft in films, sometimes having been extensively modified to outwardly resemble the aircraft it was depicting. Three aircraft were converted by Croydon -based Film Aviation Services Ltd for use in the filming of the 1962 movie Lawrence of Arabia ; one Tiger Moth became

2108-530: The effect of "weeding out" the inept student pilot. The Tiger Moth quickly became a commercial success, and examples were sold to more than 25 air forces. In addition to the military demand, aircraft were also produced for the civilian market. At one point, the flow of orders for the Tiger Moth effectively occupied almost the entirety of de Havilland's capacity to manufacture aircraft, and little capacity could be spared to accommodate domestic customers. In 1932, de Havilland also developed an affordable air taxi from

2170-537: The end of Canadian production, de Havilland Canada had manufactured a total of 1,548 of all versions, including the DH.82C and American Menasco Pirate -engined variants (with opposing "right-hand"/"counter-clockwise" rotation to the left-hand/clockwise-running Gipsy Major) known as the Menasco Moth; this also included 200 Tiger Moths that were built under wartime United States Army Air Forces (USAAF) Lend-Lease orders, which were designated for paperwork purposes as

2232-399: The firm had great success with a scaled-down version of the DH.51, the de Havilland DH.60 Moth . The starting point for the DH.82 Tiger Moth was the de Havilland DH.71 Tiger Moth . de Havilland had developed successively more capable Gipsy engines, and the company had produced a new low-winged monoplane aircraft to test them. This aircraft became the first aircraft to be referred to as

2294-525: The first 35 production aircraft for the RAF, designated K2567-K2601 , began following the issuing of Specification T.23/31; in addition two float -equipped seaplanes , S1675 and S1676 , were built according to Specification T.6/33. The de Havilland DH.82 Tiger Moth is a single-engined , biplane , taildragger aircraft with two seats in tandem configuration. It was developed principally to be used by private touring customers as well as for pilot instruction for both military and civilian operators. It

2356-582: The first Australian-assembled Tiger Moth conducted its first flight at Bankstown , Sydney . Most Australian aircraft were delivered to the Royal Australian Air Force (RAAF), but several batches were exported, including 18 for the USAAF and 41 for the Royal Indian Air Force . In New Zealand, 132 Tiger Moths were completed by de Havilland Aircraft of New Zealand ; 23 were built in Sweden as

2418-547: The front cockpit, and the rear cabane struts for the upper wing. The solution adopted was to shift the upper wing forward but sweep the wings back to maintain the same centre of lift. Other changes included a strengthened structure, fold-down doors on both sides of the cockpit, and a revised exhaust system. On 26 October 1931 the first 'true' Tiger Moth, the prototype E6 , made its maiden flight at Stag Lane Aerodrome , Edgware , London, flown by de Havilland Chief Test Pilot Hubert Broad . Shortly thereafter construction of

2480-482: The fundamental requirements of a training aircraft, in being "easy to fly, but difficult to fly well"; the aircraft's benign handling when within its limits make it easy for the novice to learn the basic skills of flight. At the same time techniques such as coordinated flight must be learnt and used effectively, and the aircraft will show up mishandling to an observant instructor or attentive pupil. As training progresses towards more advanced areas, especially aerobatics ,

2542-599: The gradual rate of acceleration of Tiger Moth manufacturing had reached the point where production capacity finally became able to exceed the demands from military customers alone. By the outbreak of the Second World War a total of 1,424 Tiger Moths had been completed by both domestic and overseas manufacturing efforts. In 1941 de Havilland transferred principal manufacturing activity for the Tiger Moth from its Hatfield factory to Morris Motors Limited at their facility in Cowley, Oxford . In 1945, British Tiger Moth production

2604-506: The last military examples when that service purchased a batch of refurbished ex-civilian examples in 1956. One became the last biplane to land on an aircraft carrier ( HMS  Eagle ) in the English Channel during the summer of 1967. On takeoff, the wind over the deck allowed the aircraft to fly, but it was slower than the carrier, which turned hard to starboard to avoid a possible collision. These planes remained in service until

2666-408: The lower wing's fabric undersurface covering. This circular bell crank is rotated by metal cables and chains from the cockpit's control columns, and has the externally mounted aileron pushrod attached at a point 45° outboard and forward of the bell crank's centre when the ailerons are both at their neutral position. This results in an aileron control system operating with barely any travel down at all on

2728-412: The normal flight phases encountered during initial training, when used for aerobatic and formation training, the Tiger Moth required skill and concentration to perform well; a botched manoeuvre could cause the aircraft to stall or spin. From 1941 onwards, all military and many civilian Tiger Moths were outfitted with antispin strakes positioned on the junction between the fuselage and the leading edge of

2790-412: The plane on to the runway at a moderate speed with just the main wheels on the ground, with the tail held up until speed reduces. It does not tend to bounce. Unlike most taildraggers, slow speed three-point landings are quite difficult because there is not enough elevator authority to bring the tail down to the correct three-point attitude. This means that the tail needs to be brought down sharply at just

2852-467: The potential to go on to fly fighter aircraft , those more suited to lower-performance machines and those who must be relegated to non-pilot aircrew positions. Because the Tiger Moth has no electrical system, it must be started by hand. Being a tail-dragging biplane, taxiing also requires care. The pilot cannot see directly ahead, so the lower wing can hit obstructions, and it is susceptible to gusts of wind on its inclined, large, upper wing. The takeoff

2914-403: The project. Only 14 Mk.1s were ever made. The Mk.2 was powered by a 7.3 kilonewtons (1,640 lbf) Armstrong Siddeley Viper engine. The Viper was also intended for a short lifespan – about 10 hours, but a "long life" version was also produced for conventional aircraft. The control systems were manufactured by various firms including Elliott Brothers , GEC and McMichael, with assistance from

2976-452: The removal of the centre-section fuel tank, alternative fuel tank configurations, all-new elevators, custom-designed fuel injectors , and the recovering of the fuselage with lighter-weight fabric. Three particular aircraft, G-APDZ , G-ANZZ and G-ANMZ , were accordingly rebuilt and were used in international competitions; the design changes led to substantially improved performance during inverted flight. Ex-RAF examples were imported to

3038-426: The right speed in order for the angular momentum to carry it down sufficiently. The open cockpit allows pilots to move their heads over the side to see the runway during approach and landing. As the aircraft is a tail dragger, it is essential to land it straight with no sideways movement, to avoid ground loops. One often undocumented feature is that the carburettor de-icing mechanism is activated automatically when

3100-413: The skill required on the part of a Tiger Moth pilot increases. The aircraft will not, like some training aircraft, "fly its way out of trouble" but will instead stall or spin if mishandled. However the stall and spin remain benign, again showing up deficient piloting without endangering the aircraft or the crew. These characteristics were invaluable to military operators, who must identify between pilots with

3162-507: The tailplane, known as Mod 11'; later on, the aileron mass balances were removed for improved spin recovery performance. In 1935, the DH.82 Queen Bee , a pilotless , radio-controlled variant of the Tiger Moth, appeared for use in training antiaircraft gunners. Use of the word drone , as a generic term for pilotless aircraft, apparently originated from the name and role of the Queen Bee (i.e.

3224-633: The throttle is reduced. This means that when an engine is running poorly due to ice the pilot must reduce power even further and then wait for the ice to melt. The aircraft is operated by many private individuals and flying clubs. Numerous examples of the Tiger Moth are still flying today (an estimated 250). The number of airworthy Tiger Moths has increased as previously neglected aircraft (or those previously only used for static display in museums) have been restored. A number of aircraft have been preserved as museum displays (amongst others) at the: Privately owned Tiger Moths, type if known, and any history of

3286-551: The time to take its place. Due to the type being inexpensive to operate and the aforementioned factors, the Tiger Moth was met with an enthusiastic reception across the civilian market. Additionally, it was put to use for new roles, including aerial advertising, aerial ambulance, aerobatic performer, crop dusting, and glider tug work. In the air-racing market, Tiger Moths were converted to a single-seat configuration, often temporarily. Several aircraft were extensively modified for greater speed; these changes included alterations such as

3348-400: The wing on the outside of the turn, while the aileron on the inside travels a large amount upwards to counteract adverse yaw . From the outset, the Tiger Moth proved to be an ideal trainer, simple and cheap to own and maintain, although control movements required a positive and sure hand as a slowness to control inputs existed. Some instructors preferred these flight characteristics because of

3410-403: The word drone is a reference to the male bee, which makes one flight in search of the female queen bee and then subsequently dies). The DH.82 had a wooden fuselage, based on that of the DH.60 Gipsy Moth (with appropriate structural changes related to cabane strut placement) and the wings of the Tiger Moth II. Queen Bees retained a normal front cockpit for test-flying or ferry flights , but had

3472-421: Was designed to apply its flaps, push the elevators up and release the trolley. Landing was made at 150–125 knots (278–232 km/h; 173–144 mph). Two controllers (azimuth and elevation) were used to align the drone on the runway. On landing it touched down on its skid and banking would cause the wingtip "shoes" to touch the runway, which controlled its path down the runway as it slowed. Between 1952 and 1986,

3534-541: Was discovered while it was undergoing trials at RAF Martlesham Heath . As a result of the Martlesham trials, a favourable report for the type was produced, which in turn led to the type soon being formally adopted as the new basic trainer of the Royal Air Force (RAF). A single prototype, designated the DH.82 Tiger Moth, was ordered by the British Air Ministry under Specification 15/31, which sought

3596-603: Was ended; by this point, Morris Motors had completed a total of 3,433 Tiger Moths. Overseas manufacturing of the type commenced in 1937; the first such overseas builder was de Havilland Canada at its facility in Downsview, Ontario . In addition to an initial batch of 25 Tiger Moths that were built for the Royal Canadian Air Force (RCAF), the Canadian firm began building fuselages, which were exported to

3658-583: Was initially designated the Project B and received serials in the A93 series. Pika is an Aboriginal Australian word meaning flier . The Jindivik was developed as a result of a bilateral agreement between Australia and the UK regarding guided missile testing. While the UK provided the missiles, Australia provided test facilities, such as the Woomera Test Range . As a result of the talks, Australia gained

3720-692: Was placed for 50 aircraft powered by the de Havilland Gipsy Major I engine (130 hp) which was the DH.82A or to the RAF Tiger Moth II. The Tiger Moth entered service at the RAF Central Flying School in February 1932. During the prewar years, increasing numbers of Tiger Moths were procured for the RAF and by overseas customers; by 1939, nearly 40 flying schools operating the type had been established, nine of which operated civilian-register models, as well. From 1937 onwards,

3782-452: Was sometimes carried, but no record shows one being dropped in action. In the aftermath of Britain's disastrous campaign in France, in August 1940 three proposals for beach defence systems were put forward; 350 Tiger Moths were fitted with bomb racks to serve as light bombers as a part of Operation Banquet . A more radical conversion involved the "paraslasher", a scythe-like blade fitted to

3844-498: Was the British DH.82 Queen Bee , a variant of the Tiger Moth trainer aircraft operational from 1935. Its name led to the present term "drone". In their simplest form, target drones often resemble radio-controlled model aircraft. More modern drones may use countermeasures , radar , and similar systems to mimic manned aircraft. More advanced drones are made from large, older missiles which have had their warheads removed. In
