SEPR 84
The SEPR 84 is a family of liquid-propellant rocket engines used as boosters for the Dassault Mirage III mixed-power high-altitude interceptor aircraft of the 1960s. The engine was one of several similar developed by SEPR (Société d'Etudes pour la Propulsion par Réaction). SEPR 841 SEPR's auxiliary rocket engines were based on the hypergolic fuel chemistry of nitric acid oxidiser and TX2 (tri-ethylamine xylidine) fuel. Unusually, the turbopump for the engine was mechanically driven from outside. A mechanical drive shaft from the accessory drive of the main turbojet provided the needed at 5,070 rpm, provided that the engine was running at full speed. As the propellants are hypergolic, the engine can be ignited repeatedly simply by engaging the clutch drive to the pump. Bulk production of the engines was carried out by Hispano-Suiza. SEPR 844 For simplicity of fuel supply, the TX2 fuel of the SEPR 841 was replaced with standard Jet TR-0 / JP-4 / JP-5 (kerosene) in the ...

Flieger-Flab-Museum
The Flieger Flab Museum (English: Swiss Air Force Museum) is located in the Canton of Zurich in Dübendorf on the grounds of Dübendorf Air Base. In the museum, 40 airplanes and helicopters are displayed, with the collection divided into distinct eras: pioneers and World War I, the 1930s, World War II and the postwar period, the beginning of the jet age, the development of jet fighters, the Cold War, and arms reduction. History The collection was founded in 1972 by the Office for Military Airfields and dedicated to the history of Swiss military aviation and air defense. In 1972–1978, the collection was turned over to the state by the Swiss Federal Office for military airfields. In 1978, for the first time, the public were able to contribute to the collection, which grew steadily over the next few years. Finally, in 1979, the Friends of the Museum of the Swiss air force (VFMF) was formed, initiated by Hans Giger, the Director of the Federal Office for military airfields. Dur ...

Dassault Mirage
Mirage is a name given to several types of jet aircraft designed by the French company Dassault Aviation (formerly Avions Marcel Dassault), some of which were produced in different variants. Most were supersonic fighters with delta wings. The most successful was the Mirage III in its many variants and derivatives, which were widely produced and modified both by Dassault and by other companies. Some variants were given other names, while some otherwise unrelated types were given the Mirage name. Early prototypes * MD550 Mystère Delta, the original Dassault experimental delta jet, which provided the baseline for the main Mirage series. Two were built, later renamed Mirage I and II respectively: ** Mirage I, being the MD550-01 renamed. ** Mirage II, being the MD550-02 renamed. Mirage III/5/50 series The most successful line of Mirages were a family of supersonic delta-winged fighters, all sharing the same basic airframe but differing in powerplant, equipment and minor details.

Saunders-Roe SR
Saunders-Roe Limited, also known as Saro, was a British aero- and marine-engineering company based at Columbine Works, East Cowes, Isle of Wight. History The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the aircraft and boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders the founder developed the Consuta material used in marine and aviation craft. The Saunders-Roe interest in aviation didn’t prevent the firm from continuing with the boatbuilding activities associated with S. E. Saunders Ltd Saunders Roe concentrated on producing flying-boats, but none were produced in very large quantities – the longest run being 31 Londons. They also produced hulls for the Blackburn Bluebird. During the Second World War Saro manufactured Supermarine Walrus and Supermarine Sea Otters. Their works at ...

English Electric Lightning
The English Electric Lightning is a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It was capable of a top speed of above Mach 2. The Lightning was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Lightning. It was operated by the Royal Air Force (RAF), the Kuwait Air Force (KAF), and the Royal Saudi Air Force (RSAF). A unique feature of the Lightning's design is the vertical, staggered configuration of its two Rolls-Royce Avon turbojet engines within the fuselage. The Lightning was designed and developed as an interceptor to defend the V bomber airfields from attack by anticipated future nuclear-armed supersonic Soviet bombers such as what emerged as the Tupolev Tu-22, but it was subsequently also required to intercept other bomber aircraft such as the Tupolev Tu-16 and the Tupolev Tu-9 ...

SNECMA Atar 101
The SNECMA ATAR 101 is a French axial-flow turbojet engine built by SNECMA. It was derived from engines and design work carried out at BMW in Germany during World War II, and extensively developed though a progression of more powerful models. The name is derived from its original design group, ''Atelier Technique Aéronautique de Rickenbach'' employing Hermann Östrich and many of the wartime BMW gas turbine design group as well as other German engine design teams. The ATAR 101 powered many of the French post-war jet aircraft, including the Vautour II, Étendard IV, Super Mystère B2, and the Mirage III-001, prototype of the Mirage III series.Gunston 1989, p. 160. Design and development At the end of World War II the French aircraft industry was in disarray, having been commandeered by the German government to produce mostly German designed aircraft and aero-engines. To develop an indigenous gas turbine aero-engine the French government acquired the services of a large conti ...

Armstrong Siddeley Viper
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. Design and development The design originally featured a seven-stage compressor based on their Adder engine — the Viper is in effect a large-scale Adder. Like the similar J85 built in United States, the Viper was originally developed as an expendable engine for production versions of the Jindivik target drone. Like the J85, the limited-life components and total-loss oil systems were replaced with standard systems for use in crewed aircraft. Because it was initially developed as an expendable engine, the Viper was subject to many recurring maintenance issues. This led to the development of the first Power by the Hour program in which operators woul ...

Dassault Mystère
The Dassault MD.452 Mystère is a 1950s French fighter-bomber. Development After the success of the Ouragan, Dassault was working on a more advanced machine which would take to the air in early 1951 as the MD.452 Mystère I. The first prototype Mystère I was essentially an Ouragan with a 30-degree swept wing and modified tail surfaces. Two further prototypes followed, powered by the Rolls-Royce Tay 250 centrifugal-flow turbojet, an improved version of the Rolls-Royce Nene, built under licence by Hispano-Suiza, and rated at thrust. These three Mystère I prototypes led to two Mystère IIA prototypes, powered by the Tay and armed with four Hispano cannon; and then four Mystère IIB prototypes, which traded the four cannon for two DEFA revolver-type cannon. A Mystère IIA was the first French aircraft to break Mach 1 in controlled flight (in a dive), on 28 October 1951. The eleven preproduction machines that followed were designated Mystère IIC, nine of which were ...
