A jet aircraft (or simply jet ) is an aircraft (nearly always a fixed-wing aircraft ) propelled by one or more jet engines .
54-638: The Canadair Sabre is a jet fighter aircraft built by Canadair under licence from North American Aviation . A variant of the North American F-86 Sabre , it was produced until 1958 and used primarily by the Royal Canadian Air Force (RCAF) until replaced with the Canadair CF-104 in 1962. Several other air forces also operated the aircraft. The aircraft was produced in two significant batches. The first,
108-552: A dive, and thus became the first woman to exceed the speed of sound. The Golden Hawks were a Canadian aerobatic flying team that was established in 1959 to celebrate the Royal Canadian Air Force's 35th anniversary and the "Golden" 50th anniversary of Canadian flight, which began with the AEA Silver Dart in 1909. Initially, a six-plane team flying brilliantly painted metallic-gold Canadair Sabre Mk.5s,
162-522: A highly flammable fabric surface. During the 1920s and 1930s a number of approaches were tried. A variety of motorjet , turboprop , pulsejet and rocket powered aircraft were designed. Rocket-engine research was being carried out in Germany and the first aircraft to fly under rocket power was the Lippisch Ente , in 1928. The Ente had previously been flown as a glider. The next year, in 1929,
216-569: A jet fighter on 26 July 1944, the day before the British Gloster Meteor entered operational service. The Me 262 had first flown on April 18, 1941, but mass production did not start until early 1944, with the first squadrons operational that year, too late for any effect on the outcome of the World War II . While only around 15 Meteors were operational during WW2, up to 1,400 Me 262 were produced, with 300 entering combat. Only
270-516: A jet-powered aircraft in 1910, the Coandă-1910 . However, to support this claim, he had to make substantial alterations to the drawings which he used to support his subsequently debunked claims. In fact the ducted-fan engine backfired, setting the aircraft on fire before any flights were ever made, and it lacked nearly all of the features necessary for a jet engine - including a lack of fuel injection, and any concern about hot jet efflux being directed at
324-509: A lower exhaust speed than turbojets, and are mostly used for high sonic, transonic, and low supersonic speeds. High bypass turbofans are relatively efficient, and are used by subsonic aircraft such as airliners. Jet aircraft fly considerably differently than propeller aircraft . One difference is that jet engines respond relatively slowly. This complicates takeoff and landing maneuvers. In particular, during takeoff, propeller aircraft engines blow air over their wings and that gives more lift and
378-544: A new oxygen system and improved maneuverability and low-speed characteristics achieved by increasing the wing chord by six in (15.2 cm) at the root and three in. (7.2 cm) at the wing tip along with fitting a small vertical wing fence. This modification, originated by North American on the F-86F, dramatically improved maneuverability, though the loss of the slatted leading edge increased landing speed and degraded low speed handling considerably. Canadair built 370 Mk 5s with
432-413: A shorter takeoff. These differences caught out some early BOAC Comet pilots. In aircraft overall propulsive efficiency η {\displaystyle \eta } is the efficiency, in percent, with which the energy contained in a vehicle's propellant is converted into useful energy, to replace losses due to air drag , gravity, and acceleration. It can also be stated as the proportion of
486-422: A speed that is the same as, or nearly the same as, the vehicle velocity. The exact formula for air-breathing engines as given in the literature, is where c is the exhaust speed, and v is the speed of the aircraft. For a long range jet operating in the stratosphere , the speed of sound is constant, hence flying at fixed angle of attack and constant Mach number causes the aircraft to climb, without changing

594-500: A version of the Whittle engine built by General Electric . The Meteor was the first production jet, with the first orders for production examples being made on 8 August 1941, the prototype first flying on 5 March 1943 and the first production aircraft flying on 12 January 1944, while the first orders for production Me 262 aircraft were not issued until 25 May 1943, and the first production Me 262 did not fly until 28 March 1944 despite

The Space Shuttle , while far faster than the X-43 or X-15, was not regarded as an aircraft during ascent as it was carried ballistically by rocket thrust, rather than the air. During re-entry it was classed (like a glider) as an unpowered aircraft. The first flight was in 1981. The Bell 533 (1964), Lockheed XH-51 (1965), and Sikorsky S-69 (1977-1981) are examples of compound helicopter designs where jet exhaust added to forward thrust. The Hiller YH-32 Hornet and Fairey Ultra-light Helicopter were among

The cycle efficiency, in percent, is the proportion of energy that can be derived from the energy source that is converted to mechanical energy by the engine . For jet aircraft the propulsive efficiency (essentially energy efficiency ) is highest when the engine emits an exhaust jet at
756-570: Is therefore an important consideration. Jet aircraft are usually designed using the Whitcomb area rule , which says that the total area of cross-section of the aircraft at any point along the aircraft from the nose must be approximately the same as that of a Sears-Haack body . A shape with that property minimises the production of shockwaves which would waste energy. There are several types of engine which operate by expelling hot gas: The different types are used for different purposes. Rockets are
810-655: The Boeing 707 to enter service in 1958 and thus to dominate the market for civilian airliners. The underslung engines were found to be advantageous in the event of a propellant leak, and so the 707 looked rather different from the Comet: the 707 has a shape that is effectively the same as that of contemporary aircraft, with marked commonality still evident today for example with the 737 (fuselage) and A340 (single deck, swept wing, four below-wing engines). Turbofan aircraft with far greater fuel efficiency began entering service in
864-805: The Nakajima J9Y Kikka , a modified, and slightly smaller version of the Me 262 that had folding wings. By the end of 1945, the US had introduced their first jet fighter, the Lockheed P-80 Shooting Star into service and the UK its second fighter design, the de Havilland Vampire . The US introduced the North American B-45 Tornado , their first jet bomber, into service in 1948. It was capable of carrying nuclear weapons, but
918-570: The Opel RAK.1 became the first purpose-built rocket aircraft to fly. The turbojet was invented in the 1930s, independently by Frank Whittle and later Hans von Ohain . The first turbojet aircraft to fly was the Heinkel He 178 , on August 27, 1939 in Rostock (Germany), powered by von Ohain's design. This was largely a proof of concept, as the problem of " creep " (metal fatigue caused by
972-488: The speed of sound . Jet aircraft generally cruise most efficiently at about Mach 0.8 (981 km/h (610 mph)) and at altitudes around 10,000–15,000 m (33,000–49,000 ft) or more. The idea of the jet engine was not new, but the technical problems involved did not begin to be solved until the 1930s. Frank Whittle , an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in
1026-548: The 1950s and 1960s, and became the most commonly used type of jet. The Tu-144 supersonic transport was the fastest commercial jet aircraft at Mach 2.35 (2,503 km/h (1,555 mph)). It went into service in 1975, but was withdrawn from commercial service shortly afterwards. The Mach 2 Concorde entered service in 1976 and flew for 27 years. The fastest military jet aircraft was the SR-71 Blackbird at Mach 3.35 (3,661 km/h (2,275 mph)). Most people use
1080-911: The 1950s in Central Europe were the early variants of the Soviet MiG- the MiG-15 , MiG-17 , MiG-19 and MiG-21 . Based on the Korean War experience, the selection of the Mk.6 Sabre to provide an effective opposition to the MiG threat proved to be a logical one. Canada's commitment to NATO was to provide 12 squadrons located at four bases – two in France ( Marville and Grostenquin ) and two in West Germany ( Zweibrücken and Baden Soellingen ). Initially,
1134-521: The 1970s. Some Orenda-powered examples became famous for other feats. Most notable was the single Mk. 3, the test-bed for the Orenda fit, which Jacqueline Cochran used in 1953 to set several speed records, including becoming the first woman to break the sound barrier . Another, an ex-RCAF Mk. 6 that left service in 1974, went on to become Boeing 's chase plane for test flights until 1991. Many of these later aircraft are now preserved in museums. In 1948,

#17327809625781188-605: The Canadair Sabres in front-line operation were in Pakistan, whose AIM-9 Sidewinder -equipped Mk. 6 models were the backbone of their air force during the Indo-Pakistani War of 1971 . These were slowly phased out after 1971, with the last examples leaving combat service in 1980. Although replaced by higher-performance designs in most other forces by the 1960s, late-model versions served in secondary roles into

On 18 May 1953, Ms. Cochran set a new 100 km speed record of 1,050.15 km/h (652.53 mph). Later on 3 June, she set a new 15 km closed circuit record of 1,078 km/h (670 mph). While she was in California, she exceeded 1270 km/h in
1296-653: The Canadian government decided to re-equip the RCAF with the F-86 Sabre with Canadair contracted to produce them in Montreal , Quebec , Canada. An initial batch of 10 aircraft was ordered for tool verification. The Korean War changed this to a production batch of 100 aircraft. Canadair slowly built up its production facility to make all components with related equipment obtained from other Canadian suppliers. Canadair gave
1350-528: The Me 262 program having started earlier than that of the Meteor, as Projekt 1065, with initial plans drawn up by Waldemar Voigt's design team in April 1939. The Messerschmitt Me 262 was the first operational jet fighter , manufactured by Germany during World War II and entering service on 19 April 1944 with Erprobungskommando 262 at Lechfeld just south of Augsburg. An Me 262 scored the first combat victory for
1404-505: The Mk 2 and the Mk 4 were identical. Of 438 Mk 4s built, approximately 70 were used temporarily by the RCAF, all surviving examples being passed to the RAF . The other Sabre 4s went directly to the RAF under a mutual aid program, equipping 11 RAF squadrons. The majority served in West Germany with NATO, with two squadrons being based in the UK as part of RAF Fighter Command . The Sabre Mk.4 served with
1458-459: The Mk. 2 and Mk. 4s, with fewer than 1,000 produced, were only slightly different from their US counterparts. The second run, the Mk. 5s and Mk. 6s of similar numbers, were patterned on the later versions of the US Sabre with larger wings for improved maneuverability while replacing the original General Electric J47 engine with the locally designed more-powerful Avro Canada Orenda . The last of
1512-540: The RAF until mid-1956 when they were replaced by Hawker Hunters . The survivors were overhauled in the UK, fitted with '6-3' wing modifications and handed to the USAF (which had funded these aircraft) which in turn passed them on to other NATO members, with the majority going to Italy and Yugoslavia. On 30 July 1953, the first Sabre Mk.5 flew with the Orenda 10 engine, which gave it a clear rate of climb and ceiling advantage over earlier variants. Other Mk 5 improvements included
1566-571: The Sabre 5 in RCAF service from 1954, just over 210 surviving Sabre 2s were overhauled and modified in the UK and supplied in roughly equal numbers to the Greek Air Force and Turkish Air Forces . In mid-1952, the Sabre Mk.4 went into production with the first one flown on 28 August 1952. Apart from some minor structural and systems changes, including improved air-conditioning and gun sight,
1620-745: The Sabre Mk.6. The last Sabre to be manufactured by Canadair (Sabre No. 1815 ), after being donated by the Pakistan Air Force , is now part of the permanent collection in the Western Canada Aviation Museum (WCAM) in Winnipeg, Manitoba . From 1950 to 1958, a total of 1,815 CL-13 Sabres were built at the Canadair plant in Montreal. The second generation of Canadair Sabre aircraft, and first to be built in quantity,
1674-623: The Sabre the project number CL-13. Canadair produced six versions of the CL-13 Sabre. The sole Sabre Mk.1 was essentially the same as the North American Sabre F-86A. It had a General Electric J47-GE-13 turbojet of 5,200 lbf (23 kN) thrust. The Sabre Mk.2 had the same engine, although after the first 20 aircraft were produced, the remainder of the production run was distinguished in having power-assisted controls and an "all-flying" tailplane . The sole Sabre Mk.3

1728-804: The contribution consisted of only Sabre aircraft; however, later it was decided to include the Avro Canada CF-100 aircraft in the defense package to provide a night and all-weather fighter capability. Though the main use of the Sabre by the RCAF was in Europe, they were also used by RCAF Auxiliary part-time units in Canada, replacing de Havilland Vampire jets. 400 "City Of Toronto" and 411 "County Of York" Squadrons based at RCAF Station Downsview near Toronto, as well as 401 "City Of Westmount" and 438 "City Of Montreal" Squadrons at RCAF Station St-Hubert near Montreal, were equipped with Sabre 5s, as
1782-492: The early 1930s. In August 1939 the turbojet powered Heinkel He 178 , the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. After the first instance of powered flight, a large number of jet engine designs were suggested. René Lorin , Morize, Harris proposed systems for creating a jet efflux. After other jet engines had been run, Romanian inventor Henri Coandă claimed to have built
1836-458: The first commercial jet service, from London to Johannesburg , in 1952 with the de Havilland Comet jetliner . This highly innovative aircraft travelled far faster and higher than propeller aircraft, was much quieter, smoother, and had stylish blended wings containing hidden jet engines. However, due to a design defect, and use of aluminium alloys, the aircraft suffered catastrophic metal fatigue which led to several crashes, which gave time for
1890-495: The high temperatures within the engine) had not been solved, and the engine quickly burned out. Von Ohain's design, an axial-flow engine, as opposed to Whittle's centrifugal flow engine, was eventually adopted by most manufacturers by the 1950s. The first flight of a jet-propelled aircraft to come to public attention was the Italian Caproni Campini N.1 motorjet prototype which flew on August 27, 1940. It
1944-641: The larger, heavier and older Sabre. The Gnat was referred to as a "Sabre Slayer" by the Indian Air Force since most of its combat kills during the two wars were against Sabres. Although the Canadair Sabre Mk.6 was widely regarded as the best dogfighter of its era, tactics called for Gnats taking on the Sabres in the vertical arena, where the Sabres were at a disadvantage. Moreover, because the Gnat
1998-550: The main day fighter of the Pakistan Air Force. Canadair Sabres were the mainstay of their respective air forces in the two major conflicts in which they were employed: the Korean War, where F-86 Sabres racked up a 6-1 kill record, and the Indo-Pakistani War of 1971 . The diminutive Folland Gnat was its main opponent in the Indo-Pakistan war. By the end of 1971, the Gnat proved to be a frustrating opponent for
2052-508: The majority designated for use in the RCAF's Air Division squadrons in Europe to replace the Mk.2s. A total of 75 RCAF Sabre 5s were transferred to the German Luftwaffe during 1957. The Canadair Sabre Mk.6 was the final variant and was considered to be the best production Sabre ever built. It was equipped with a two-stage Orenda engine developing 7,275 pounds (3,300 kg)) of static thrust. Its altitude performance and climb rate
2106-476: The many helicopters where the rotors were driven by tip jets . Jet-powered wingsuits exist – powered by model aircraft jet engines – but of short duration and needing to be launched at height. Because of the way they work, the typical exhaust speed of jet engines is transonic or faster, therefore most jet aircraft need to fly at high speeds, either supersonic or speeds just below the speed of sound (" transonic ") so as to achieve efficient flight. Aerodynamics
2160-576: The mechanical energy actually used to propel the aircraft. It is always less than 100% because of kinetic energy loss to the exhaust, and less-than-ideal efficiency of the propulsive mechanism, whether a propeller , a jet exhaust, or a fan. In addition, propulsive efficiency is greatly dependent on air density and airspeed. Mathematically, it is represented as η = η c η p {\displaystyle \eta =\eta _{c}\eta _{p}} where η c {\displaystyle \eta _{c}}
2214-399: The oldest type, and are mainly used when extremely high speeds are needed, or operation at extremely high altitudes where there is insufficient air to operate a jet engine. Due to the extreme, typically hypersonic , exhaust velocity and the necessity of oxidiser being carried on board, they consume propellant extremely quickly, making them impractical for routine transportation. Turbojets are

2268-562: The rocket-propelled Messerschmitt Me 163 Komet was a faster operational aircraft during the war. Around this time, mid 1944, the United Kingdom's Meteor was being used for defence of the UK against the V-1 flying bomb – the V-1 itself a pulsejet -powered aircraft and direct ancestor of the cruise missile – and then ground-attack operations over Europe in the last months of
2322-409: The second oldest type; they have a high, usually supersonic, exhaust speed and low frontal cross-section, and so are best suited to high-speed, usually supersonic, flight. Although once widely used, they are relatively inefficient compared to turboprop and turbofans for subsonic flight. The last major aircraft to use turbojets were Concorde and Tu-144 supersonic transports . Low bypass turbofans have
2376-484: The term 'jet aircraft' to denote gas turbine based airbreathing jet engines , but rockets and scramjets are both also propelled by jet propulsion. Cruise missiles are single-use unmanned jet aircraft, powered predominantly by ramjets or turbojets or sometimes turbofans, but they will often have a rocket propulsion system for initial propulsion. The fastest airbreathing jet aircraft is the unmanned X-43 scramjet at around Mach 9–10. The fastest manned (rocket) aircraft

In 1944 Germany introduced the Arado Ar 234 jet reconnaissance and bomber aircraft into service, though chiefly used in the former role, with the Heinkel He 162 Spatz single-jet light fighter appearing at the end of 1944. USSR tested its own Bereznyak-Isayev BI-1 in 1942, but the project was scrapped by leader Joseph Stalin in 1945. The Imperial Japanese Navy also developed jet aircraft in 1945, including

In addition to the RCAF deliveries, 225 Canadair Mk.6 Sabres were exported to the West German Luftwaffe , six were delivered to the Colombian Air Force , and 34 went to the South African Air Force . In January 1966, Germany sold 90 of its Canadian Mk 6 Sabres to Iran. These aircraft were quickly transferred to Pakistan and became

The first production model was completed on 2 November 1954 and ultimately 655 were built with production terminating on 9 October 1958. A total of 390 Mk.6s went to the RCAF with the majority replacing the existing Canadair Sabre Mk.5s at the Air Division squadrons in West Germany and France. The main air threats to NATO in

In the following year, another plane was added to the team, allowing for a five-plane main formation with two solo jets. The Golden Hawks continued performing for three more seasons, changing to the Mk 6 in 1961, until they were disbanded on 7 February 1964, having flown

In 1952, Jacqueline Cochran , then aged 47, decided to challenge the world speed record for women, then held by Jacqueline Auriol . She tried to borrow an F-86 from the U.S. Air Force, but was refused. She was introduced to an Air Vice-Marshal of the RCAF who, with the permission of

During the first half of 1952, the remaining 60 Mk.2s were supplied to the U.S. Air Force for use in the Korean War . Most RCAF Mk.2 Sabres were utilized in the air defence role with NATO's No. 1 Air Division in Europe, proving itself to be an outstanding dogfighter. Others were assigned to the training role at bases in Canada. After replacement by

Campini began development of the motorjet in 1932; it differed from a true turbojet in that the turbine was driven by a piston engine, rather than combustion of the turbine gases - which was a much more complex solution. The British experimental Gloster E.28/39 first flew on May 15, 1941, powered by Sir Frank Whittle 's turbojet. The United States Bell XP-59A flew on October 1, 1942, using two examples of
