The Siren C.30 Edelweiss is a single-seater standard class glider produced by the French company SIREN SA .
history
The designer was Jean Cayla, who had previously developed gliders for the Breguet company. The maiden flight of the first of two prototypes took place on September 25, 1962, while the first in a series of 15 aircraft was completed in January 1965. The production version no longer has the forward-swept wings used in the prototypes, furthermore the ailerons and air brakes have a smaller span and the fuselage nose is made shorter.
construction
The "Edelweiss" is a cantilevered shoulder wing decker with a NACA profile of the 64 series, but which has been modified. The single-spar wings are made entirely of wood and have a sandwich paneling made of plywood and Klégecel (a rigid foam usually used for sound and heat insulation ) with a thickness of 8 mm. The ailerons are made of all-metal. The fuselage is also constructed in the same sandwich construction as the wings. The tail unit has a V - or butterfly shape with an included angle of 90 °. The unicycle undercarriage is not retractable.
commitment
Both prototypes took part in the 1963 World Championships in Argentina, with second (Lacheny) and 17th place in the standard class. At the World Championships in England in 1965, the aircraft type reached 1st and 7th place. The Frenchman Louis Henry was the world champion in gliding.
