Infos techniques | Empennage en T. The immediate precursor of the Mistral-C Club Class glider was the Strauber Mistral high performance Standard Class aircraft designed by Manfred Strauber, Alois Fries, Hartmut Frommhold and Horst Gaber. In October 1974 the design of a new model was begun by Strauber and Frommhold, now operating as Ingenieur-Büro Strauber - Frommhold Gmbh. This became the Mistral-C or model 2 Mistral-C and was one of the first gliders to meet the specifications of the then new FAI Club Class. It first flew on 21 October 1976. The main changes were to the wings and, overall, to the construction materials. As detailed in the Specification section below, the wing area was increased, though the span was unchanged, reducing the aspect ratio and consequentially the performance. The new wings had different Wortmann sections, quarter chord forward sweep of 1.0° and dihedral 4.30°. GRP/PVC foam sandwich replaced the earlier balsa sandwich in the wings and the ailerons and fuselage were all GRP. As in the wings, the PMI foam in the tail was replaced by PVC and the all moving tail was changed to a fixed tailplane, fitted with a spring tab. The canopy is side-hinged. The Mistral-Cs produced by Valentin were little different, though the dihedral is reported to be 4.20°. | ||||||||||
Histoire résumée | Le Mistral-C fut l'un des tout premiers planeur de la classe Club. Son étude, basée sur le Classe Standard Strauber Mistral, débuta en 1974. Le premier vol du prototype eut lieu le 21 October 1976. Plus de 75 Mistral-C furent construits. In 2010 54 Mistral-C figuraient sur les registres européens de l'aviation civile et 3 autres étaient encore enregistrés en Grande-Bretagne en 2012. Le Mistral-C termina 3e (sur 33 concurrents) du premier concours international de la classe Club qui eut lieu en Suède en 1979. | ||||||||||
