The Cerva CE-75 Silene is a trainer aircraft designed glider of the French manufacturer Cerva. The aircraft received French type certification in early 1978 and a short time later production began with two copies per month.
history
1972 founded the French aircraft manufacturer Wassmer Aviation together with SIREN the joint venture -Unternehmen Consortium Europeén de Réalisation et de Ventes d'Avions (CERVA) to build common aircraft. The Cerva CE-75 was also created during this collaboration. Development of the model, which was designed for pilot training, began on January 1, 1972, and construction of the prototype began on February 1, 1973 . On July 2, 1974, the maiden flight finally took place and on February 3, 1978 the aircraft received the French type certification . By the spring of 1978, forty orders for the CE-75 had been placed and six had been built. After Wassmer Aviation was dissolved in early 1978 due to bankruptcy, SIREN founded the Societe Issoire and continued building the aircraft under the name Siren E-75.
construction
The CE-75 is a cantilevered middle decker made of glass fiber reinforced plastic in a sandwich construction . The wings have a span of eighteen meters and have a Bertin E55-166 profile . On Flügelober- and bottom are Schempp-Hirth - air brakes fitted. The cockpit, which can optionally be equipped with an oxygen supply , has two seats that are slightly offset next to each other in order to keep the fuselage as narrow as possible. The cockpit canopy opens to starboard and can be released. The chassis consists of a single main wheel that can be retracted in the first six copies built. A rigid chassis can also be installed as an option.
