A gyrodyne is a type of VTOL aircraft with a helicopter rotor -like system that is driven by its engine for takeoff and landing only, and includes one or more conventional propeller or jet engines to provide thrust during cruising flight . During forward flight the rotor is unpowered and free-spinning, like an autogyro (but unlike a compound helicopter ), and lift is provided by a combination of the rotor and conventional wings . The gyrodyne is one of a number of similar concepts which attempt to combine helicopter-like low-speed performance with conventional fixed-wing high-speeds, including tiltrotors and tiltwings .

84-472: In response to a Royal Navy request for a helicopter, Dr. James Allan Jamieson Bennett designed the gyrodyne whilst serving as the chief engineer of the Cierva Autogiro Company . The gyrodyne was envisioned as an intermediate type of rotorcraft , its rotor operating parallel to the flightpath to minimize axial flow with one or more propellers providing propulsion. Bennett's patent covered

The "Fairey V.T.O" was a vertical take-off delta wing aircraft was designed to explore the possibility of making an aircraft launched from short ramps with low acceleration. Shown for the first time at the Society of British Aircraft Constructors (SBAC) Show in 1952,

252-565: A Defense Advanced Research Projects Agency (DARPA) program to develop advances in rotorcraft technology with the goal of overcoming the current limitations of helicopters in both speed and payload. Where a conventional helicopter has a powered rotor which provides both lift and forward thrust, and is capable of true VTOL performance, a gyroplane or autogyro has a free-spinning rotor which relies on independent powered thrust to provide forward airspeed and keep it spinning. The gyrodyne combines aspects of each. It has an independent thrust system like

336-473: A crew of three. For training purposes the Malkara Mk I was used, with a range of some 2,000 m (6,600 ft). The operational weapon was the Malkara Mk 1 A, which had a different type of tracking flare, thinner guidance wire, and other improvements to give approximately double the range of Mk 1. The Fairey Fireflash was an early air-to-air weapon guided by radar beam riding. Developed as "Blue Sky" –

420-693: A derated version of the Red Hawk missile. It was in service briefly before being replaced by the de Havilland Firestreak . Green Cheese was a tactical nuclear anti-ship missile for use with the Gannet. Problems with Gannet led to continued development with the Blackburn Buccaneer but it was cancelled. Fairey Marine Ltd was begun in the late 1940s by Sir Richard Fairey and Fairey Aviation's Managing Director, Mr Chichester-Smith. Both were avid sailing enthusiasts. Utilising techniques developed in

504-514: A design and production factory that specialised in the manufacture of airborne and ground equipment for target aircraft and missile fields including the Tonic towed target, which can be carried and streamed by a Jindivik 3A. In 1957 a miniature camera by the name of WRECISS ( Weapons Research Establishment camera interception single-shot) was designed and developed by the WRE at Woomera and manufactured by

588-420: A finely finished, white-painted body apparently made of seamless tube. About two-thirds of the way back from the nose was fitted a laminated-wood wing of about two feet span, positioned across a diameter of the body, with a root chord of some 18 inches and a quarter-chord sweep of about 50 degrees. In April 1947 Fairey released details of its first guided missile It was an anti-aircraft weapon designed for use in

672-503: A management buy-out from Pearson, listing on the London Stock Exchange in 1988. During the 1990s this company concentrated on expanding its electronics business, acquiring a number of companies, and disposing of the electrical insulator and hydraulic actuator businesses. In 1997, the company acquired Burnfield, of which Malvern Instruments was the most significant company. Servomex plc was acquired in 1999. In July 2000,

756-468: A mechanical overdrive unit for Land Rovers. Vehicles fitted with the unit carried a badge on the rear saying "Overdrive by Fairey", with the Fairey logo (see above). This branch of products effectively ceased in the early 1980s when new product development at Land Rover and a trend for manufacturers to build accessories in-house forced Fairey to drop out of the sector. The American company Superwinch bought

840-707: A range of subsonic and supersonic towed target systems (RADOP) for air-to-air and surface-to-air guided weapon training in Europe, Africa, the Middle East, the Commonwealth and the UK. The parent Fairey Company and its Australian subsidiary were heavily involved guided weapon development. The Weapon Division of Fairey Engineering Ltd was responsible in the UK for the Jindivik Mk 2B Pilotless target aircraft. This had

924-536: A rotaplane (with the rotor free for autorotation and an upward total axial flow through the rotor disc), on the one hand, and a pure helicopter (with the rotor driven, and a downward total axial flow through the rotor disc), on the other hand, that is with a mean axial flow through the rotor disc substantially zero at high forward speed. Bennett's concept described a shaft-driven rotor, with anti-torque and propulsion for translational flight provided by one or more propellers mounted on stub wings. With thrust being provided by

1008-734: A single manufacturer. The merger of Fairey's aviation interests with Westland Aircraft took place in early 1960 shortly after Westland had acquired the Saunders-Roe group and the helicopter division of the Bristol Aeroplane Company . Westland Aircraft and the Fairey Company announced that they had reached agreement for the sale by Fairey to Westland of the issued share capital of Fairey Aviation, which operated all Fairey's UK aviation interests. Westland acquired all Fairey's aircraft manufacturing business (including

1092-507: A variety of designs, which has led to some of the terminology confusion – other issues including the trademarked Gyrodyne Company of America and the Federal Aviation Administration (FAA) classification of rotorcraft. In recent years, a related concept has been promoted under the name heliplane . Originally used to market gyroplanes built by two different companies, the term has been adopted to describe

1176-542: A warhead. The Stooge required a launching ramp and transport. The missile was extensively tested at Woomera The Malkara missile was designed in Australia by British and Australian companies. It was a heavy wire-guided missile for deployment from vehicles, light naval craft and fixed emplacements. This weapon replaced the Fairey "Orange William" project for the MoS which would later lead to Swingfire . Fairey Engineering had

1260-519: Is working on phase one of that program, a 15-month effort… (it) combines the "gyroplane"… with a fixed-wing business jet. The team was using the Adam A700 , in the very-light-jet class …" There were issues with tip jet noise, and the program was cancelled in 2008. An industry magazine describes the gradual evolution of traditional helicopters as "slow" and lacking revolutionary steps, and non-traditional compounds are still not widespread. "Gyrodyne"

1344-607: The Avro CF-100 . The Canadair Argus used Fairey-designed hydraulic actuators. The company also produced the "Bear Trap" helicopter /ship handling system for the Royal Canadian Navy. In the early 1960s the company undertook the conversion of the Martin Mars flying boats to water-bearing firefighters. Drawing on the parent company's expertise in the design of hydraulic equipment led to local manufacturer of

1428-576: The Fairey III family, the Swordfish , Firefly , and Gannet . It had a strong presence in the supply of naval aircraft, and also built bombers for the RAF. After World War II the company diversified into mechanical engineering and boat-building. The aircraft manufacturing arm was taken over by Westland Aircraft in 1960. Following a series of mergers and takeovers, the principal successor businesses to

1512-818: The Grumman Avenger . The Avro Lancaster conversion programme created the need for plant expansion. The Lancaster was followed in service by the Lockheed Neptune and again the company undertook a share of the repair overhaul and service of these aircraft. The company was engaged in the modification and overhaul of the McDonnell Banshee . Fairey of Canada also developed a component and instrument design and manufacturing organisation. The company began manufacture of Hydro Booster Units which control flight surfaces hydraulically rather than manually. Other flight controls were designed and manufactured for

1596-637: The Jindivik , Meteor, and Canberra drones at Woomera missile test range. Fairey Australasia was the first company to be established at the Weapons Research Establishment (WRE). This was in 1949 when the firm was involved in supporting research trials of the scale model of the Fairey vertical-take-off aircraft. Shortly afterwards the company expanded to manufacture the RTV.l research rockets that were fired in Australia. From this developed

1680-475: The McDonnell XV-1 was developed as a rotorcraft with tip jets to provide vertical takeoff capability. The aircraft also had wings and a propeller mounted on the rear of the fuselage between twin tailbooms with two small rotors mounted at the end for yaw control. The second prototype of XV-1 became the world's first rotorcraft to exceed 200 mph in level flight on 10 October 1956. No more were built and

1764-648: The Pacific War but not completed in time for use by the British Army (who originally ordered it) or for the Royal Navy . The Ministry of Supply requested that the work be completed, and the Stooge was the outcome. It had a length of 7 ft 5.5 in (2.273 m), a span of 6 ft 10 in (2.08 m), a body diameter of 17 in, and weighing 738 lb (335 kg), with a warhead. Propulsion

Some parts were also imported from the UK. Assembly was undertaken at Salisbury, South Australia by the Special Projects Division of Fairey. Test firings took place in 1955–56 but by this time the RTV1 was considered obsolete RTV1e

1932-513: The Royal Navy an aircraft capable of true vertical flight. Bennett's innovative design, a new type of rotorcraft that combined key features of the autogyro and helicopter, was tendered to the Air Ministry ( Specification S.22/38 ) as the Cierva C.41 Gyrodyne, but preliminary work was abandoned with the outbreak of World War II . Bennett joined Fairey Aviation in 1945, where he continued

2016-777: The United Kingdom by Avro , in Germany by Focke-Wulf , and in France by Lioré-et-Olivier . On 9 December 1936, Cierva was killed in the Croydon KLM airliner accident when the aircraft in which he was a passenger crashed after taking off in fog. Dr. James Allan Jamieson Bennett was promoted to Chief Technical Officer of the company and remained in the position until leaving in 1939. In addition to making important contributions to autogyro controls while at Cierva Autogyro, Bennett carried through with Cierva's decision to offer

2100-1380: The Westland Wasp and Westland Scout were built at Hayes in the 1960s. Receipt of large UK military contracts in the mid-1930s necessitated acquisition of a large factory in Heaton Chapel Stockport in 1935 that had been used as the National Aircraft Factory No. 2 during World War I. Flight test facilities were built at Manchester's Ringway Airport, the first phase opening in June 1937. A few Hendon monoplane bombers built at Stockport were flown from Manchester's Barton Aerodrome in 1936. Quantity production of Battle light bombers at Stockport/Ringway commenced in mid 1937. Large numbers of Fulmar fighters and Barracuda dive-bombers followed during World War II. Fairey's also built 498 Bristol Beaufighter aircraft and over 660 Handley Page Halifax bombers in their northern facilities . Postwar, Firefly and Gannet naval aircraft were supplemented by sub-contracts from de Havilland for Vampire and Venom jet fighters. Aircraft production and modification at Stockport and Ringway ceased in 1960. On 13 March 1959 Flight reported that Fairey Aviation Ltd

2184-423: The autogyro . The company was set up to further the designs of Juan de la Cierva , a Spanish engineer and pilot, with the financial backing of James George Weir , a Scottish industrialist and aviator. Juan de la Cierva's first British-built autogyro was the C.8 design . It and some other designs were built in conjunction with Avro . The pre-war Cierva C.30 proved popular. Nearly 150 were built under licence in

2268-500: The 1944 Royal Navy specification for a guided anti-aircraft missile known as LOPGAP. In 1947, the Royal Aircraft Establishment took over development work and the missile was renamed RTV1. Several versions of the basic RTV1 were developed. The Fairey Aviation Company of Australasia Pty Ltd was awarded a contract to build 40 RTV1e rockets. The first of which were completed in early 1954. Components were built by

The Special Projects Division built

4956-451: The gyrodyne concept around 2007. Aircraft developed for the project would use a rotor for takeoff and landing vertically, and hovering, together with substantial wings to provide most of the required lift at cruise, combining the large cargo capacity, fuel efficiency, and high cruise speed of fixed-wing aircraft with the hovering capabilities of a helicopter. The project was "…a multi-year $ 40-million, four-phase program. Groen Brothers Aviation

5040-411: The main thrust drives the craft forwards, air flows through the rotor disc from below, causing it to spin and create lift. The gyrodyne is capable of transitioning between these two modes of flight. Typically a gyrodyne also has fixed wings which provide some of the lift during forward flight, allowing the rotor to be offloaded. A computer simulation has suggested an optimum distribution of lift of 9% for

5796-428: Was about 17 ft in length with a diameter of 10 in. The body was fitted with four wings and four small control vanes. Fairey Australia also displayed an aerodynamic test vehicle, described as a "three-inch winged round". This was a simple projectile, without guidance, to aid investigations into the properties of various wing/body assemblies at high supersonic speeds. The example shown was about 6 ft long, and had

5880-474: Was absorbed into what eventually became Blom Aerofilms. Subsidiary companies were as follows:— Other companies were located in Nigeria, Zambia and the Republic of Ireland. The Fairey factory at Heaton Chapel , Stockport can trace its roots back to when Crossley Bros. Ltd having had by the end of 1916 supplied large numbers of tenders and aero engines to the Royal Flying Corps acquired premises at High Lane, Heaton Chapel to expand production. In 1917, following

5964-400: Was acquired by Fairey. In 1935 the Fairey company received a substantial order for Hendon night bombers and established production lines at the Heaton Chapel factory. The production facilities at Heaton Chapel were incorporated as the Stockport Aviation Company Limited on 11 February 1936 and the Company took a site at Ringway (now Manchester Airport), where test flights were carried out. After

6048-518: Was also involved in the early development of pilotless aircraft which led to the development of radio controlled pilotless target aircraft in Britain and the United States in the 1930s. In 1931, the Fairey "Queen" radio-controlled target was developed, building a batch of three. The Queen was a modified Fairey IIIF floatplane, (a catapult launched aircraft which was used for reconnaissance by

6132-491: Was by four 75 lbf (330 N)-thrust solid-fuel main rockets, but initially four additional booster rockets delivering further 5,600 lb thrust accelerated the Stooge off its 10 ft (3.0 m) long launching ramp. Unlike later designs, the Stooge was intended for high subsonic speeds—and limited ranges. The Stooge consisted of two-stage propulsion, an autopilot, radio control equipment with additional ground unit, and

6216-573: Was fired at an angle of 35 degrees with a maximum altitude of about 12,000 feet. The vehicle was launched by seven solid booster rockets which had a burn time of four seconds, after which the liquid fuel sustainer motor took over. At the 1954 Farnborough Airshow , Fairey Australia displayed a massive missile resembling the RTV-1. The base was formed by a booster unit about 6 ft high and 20 inches in diameter, stabilised by four large and four small fins and housing seven five-inch motors. The main body

6300-599: Was granted as a trademark to the Gyrodyne Company of America in 1950. The company was not involved in gyrodyne development, but instead produced a turbine-engined, remotely piloted drone helicopter, with coaxial rotors , for the United States Navy , designated as the QH-50 DASH . Cierva Autogiro Company The Cierva Autogiro Company was a British firm established in 1926 to develop

6384-477: Was home to the weapon division, which had a contract for research into advanced anti-tank missile systems. Fairey's remaining net worth was approximately £9.5m. In 1977 the Fairey Group went into receivership and was effectively nationalised by the Government. Fairey went into liquidation when it introduced a Britten-Norman Islander production line into its subsidiary company, Avions Fairey, and overproduced

6468-428: Was initially headquartered at 24 Bruton Street , London W1. and later at Reform Road, Maidenhead, with companies across the world. The aircraft ( Douglas Dakotas ) and technical offices were based at White Waltham, Berks, along with a special research laboratory. Here the company undertook the design and development of anti-vibration isolators which were incorporated into camera mountings. Both mapping and geophysical work

6552-813: Was issued a patent from the UK Patent Office , assigned to the Cierva Autogiro Company. On 23 August 1940 the Autogiro Company of America , licensees of the Cierva Autogiro Company, Ltd., filed a corresponding patent application in the United States . On 27 April 1943, US patent #2,317,340 was issued to the Autogiro Company of America. The patents describe a gyrodyne as: a rotary wing aircraft intermediate in type, hereinafter referred to as "gyrodyne", between

6636-579: Was located at the Hayes factory, and used designs based on the patents of Sylvanus Albert Reed . C. R. Fairey first encountered Reed's products in the mid-1920s when investigating the possibilities of the Curtiss D-12 engine. The Curtiss company also manufactured propellers designed by Reed. Another example of utilising the talents of independent designers was the use of flaps, designed by Robert Talbot Youngman ( Fairey-Youngman flaps ) which gave many of

6720-418: Was the beam guidance test vehicle. Radar guidance was provided by a radar unit which projected a narrow beam. Different versions of the test vehicle were created and each was concerned with a different aspect of control, guidance, propulsion and aerodynamics of the complete rocket. The RTV 1e was a two-stage liquid fuel rocket used for research and development into problems associated with beam riding missiles. It

6804-867: Was then taken over by the Kidde portion of the American United Technologies Corporation. in 2000, and became now known as WFEL Ltd. In 2006 the Manchester Evening News reported that private equity investors Dunedin Capital Partners backed a management buy-out of WFEL from UTC which employs 160 people at its factory on Crossley Road, Heaton Chapel. In the post-war period, from the late 1950s onwards, Fairey acquired Mayflower Automotive Products, including their factory in Tavistock , Devon , and with it

6888-600: Was to be reorganised following a proposal to concentrate aircraft and allied manufacturing activities in the United Kingdom into a new wholly owned subsidiary called the Fairey Aviation Co. Ltd . The Board felt that the change, taking effect on 1 April 1959, would enable the Rotodyne and other aircraft work to be handled by a concern concentrating on aviation. It is proposed to change the company's name to

6972-478: Was undertaken. The UK based aircraft were sent out to work all over the world. The company undertook aerial surveys for local authorities within the UK and for many overseas Governments. Maps were also published under the Fairey-Falcon imprint. Over the years the companies names were changed to reflect Fairey ownership and operated into the late 1970s, later becoming Clyde Surveying Services Ltd. Fairey Surveys

7056-468: Was updated and built by Fairey Aviation as the FB-1 Gyrodyne commencing in 1945. Fairey's development efforts were initially led by Bennett, followed by his successor Dr. George S. Hislop . George B.L. Ellis and Frederick L. Hodgess, engineers from the pre-WW2 Cierva Autogiro Company, Ltd., joined Bennett at Fairey Aviation. The first Fairey Gyrodyne prototype crashed during a test flight, killing
