Folland Aircraft was a British aircraft manufacturing company which was active between 1937 and 1963.
The Northrop YF-17 was a prototype lightweight fighter aircraft designed by Northrop aviation for the United States Air Force's Lightweight Fighter (LWF) technology evaluation program. The LWF was initiated because many in the fighter community believed that aircraft like the F-15 Eagle were too large and expensive for many combat roles. The YF-17 was the culmination of a long line of Northrop designs, beginning with the N-102 Fang in 1956, continuing through the F-5 family.
The Folland Gnat is a British compact swept-wing subsonic fighter aircraft that was developed and produced by Folland Aircraft. Envisioned as an affordable light fighter in contrast to the rising cost and size of typical combat aircraft, it was procured as a trainer aircraft for the Royal Air Force (RAF) as well as by export customers, who used the Gnat in both combat and training capacities.
The Saunders-Roe SR.53 was a British prototype interceptor aircraft of mixed jet and rocket propulsion developed for the Royal Air Force (RAF) by Saunders-Roe in the early 1950s. As envisaged, the SR.53 would have been used as an interceptor aircraft, using its rocket propulsion to rapidly climb and approach incoming hostile bombers at high speeds; following its attack run, the aircraft would then return to its base using jet propulsion.
Bristol Siddeley Engines Ltd (BSEL) was a British aero engine manufacturer. The company was formed in 1959 by a merger of Bristol Aero-Engines Limited and Armstrong Siddeley Motors Limited. In 1961 the company was expanded by the purchase of the de Havilland Engine Company and the engine division of Blackburn Aircraft. Bristol Siddeley was purchased by Rolls-Royce Limited in 1966.
The Northrop XP-79, USAAF project number MX-365, was a rocket and jet-powered flying wing fighter aircraft, designed by Northrop. The pilot operated the aircraft in a prone position, permitting him to withstand much greater g-forces in pitch. It also used a welded magnesium monocoque structure instead of riveted aluminum.
William Edward Willoughby "Teddy" Petter was a British aircraft designer. He is noted for Westland's wartime aeroplanes, as well as the Canberra, the early design of the Lightning, and his last plane, the Folland Gnat.
The BQM-74 Chukar is a series of aerial target drones produced by Northrop. The Chukar has gone through three major revisions, including the initial MQM-74A Chukar I, the MQM-74C Chukar II, and the BQM-74C Chukar III. They are recoverable, remote controlled, subsonic aerial target, capable of speeds up to Mach 0.86 and altitudes from 30,000 to 40,000 ft.
The Bréguet Br 960 Vultur was a prototype two-seat carrier-based attack and anti-submarine aircraft (ASW) built for the French Navy during the early 1950s. Meeting contradictory endurance and speed requirements, it was designed as a "mixed-power" aircraft with a turboprop engine in the front and a turbojet in the rear. Only two examples were built, but the second aircraft was rebuilt as the prototype of the Bréguet 1050 Alizé ASW aircraft after the Navy dropped the idea of a turboprop attack aircraft in the mid-1950s.
The Dassault MD.452 Mystère is a 1950s French fighter-bomber. It was a straightforward development of the successful Dassault Ouragan
The General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to 3,500 lbf (16 kN) of thrust dry; afterburning variants can reach up to 5,000 lbf (22 kN). The engine, depending upon additional equipment and specific model, weighs from 300 to 500 pounds. It is one of GE's most successful and longest in service military jet engines, with the civilian versions having logged over 16.5 million hours of operation. The United States Air Force plans to continue using the J85 in aircraft through 2040. Civilian models, known as the CJ610, are similar but supplied without an afterburner and are identical to non-afterburning J85 variants, while the CF700 adds a rear-mounted fan for improved fuel economy.
The Armstrong Siddeley Viper is a British turbojet engine developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. It entered service in 1953 and remained in use with the Royal Air Force, powering its Dominie T1 navigation training aircraft until January 2011.
The HAL Ajeet was a jet-powered fighter aircraft developed and manufactured by Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL). It was operated by the Indian Air Force (IAF) between 1977 and 1991.
The Bristol Siddeley Orpheus is a single-spool turbojet developed by Bristol Siddeley for various light fighter/trainer applications such as the Folland Gnat and the Fiat G.91. Later, the Orpheus formed the core of the first Bristol Pegasus vectored thrust turbofan used in the Harrier family.
The Pratt & Whitney JT12 is a small turbojet engine. The Pratt & Whitney T73 is a related turboshaft engine.
The Helwan HA-300 was a single-engine, delta-wing, light supersonic interceptor aircraft developed in Egypt during the 1960s.
The SNCASE S.E.5000 Baroudeur was a French single-engined lightweight fighter designed by SNCASE (Sud-Est) and evaluated in the NATO NBMR-1 "Light Weight Strike Fighter" competition. An unusual design without a conventional landing gear, it used a wheeled trolley for take-off and three retractable skids to land. The Baroudeur did not enter production.
The Avro 720 was an in-development British single-seat interceptor of the 1950s. It was designed and being developed by Avro in competition with the Saunders-Roe-built SR.53. While at least one prototype was partially-constructed, the order for the Avro 720, and quickly thereafter the project entirely, was terminated prior to any aircraft having been completed.
The Northrop N-102 Fang was a fighter aircraft design created by Northrop Corporation and proposed to the United States Air Force in 1953. The Fang was explicitly designed as a ”light” or “lightweight fighter” in direct response to what Northrop saw as the ever-increasing weight, size, complexity, and cost of Western fighter designs. While the Fang was ultimately overlooked in-favor of the Lockheed F-104 Starfighter, Northrop’s interest in the lightweight fighter concept would ultimately come to fruition with the F-5 Freedom Fighter, itself spawning a moderately successful fighter family.
Squadron Leader Edward Alan Tennant DFC was a Royal Air Force (RAF) fighter pilot who later became chief test pilot of Folland Aircraft.
