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.
