aircraft Schools. Durability research

to Pass to sections: aircraft Schools

The First attempt of an establishment of standard requirements to durability of the plane concerns the end of 1916 At RIB the Commission concerning norms of durability has been created. Under the direction of N.E.Zhukovskogo as a part of G.A.Botezata, V.P.Vetchinkina, G.I.Lukjanova, With. P.Timoshenko and its other members the commission has held two sessions.

Research of durability various samoletnyhkonstruktsy has allowed to define in 1916 the first sketches of norms of durability. The flight scientific researches spent by employees RIB together with pilots of the Moscow school of aircraft, have led to a number of the important conclusions in the field of durability depending on overloads of devices from flaws before landing and at various maneuvers.

During the work RIB has given many new materials poproektirovaniju and to plane calculation. Developments of new profiles of bearing surfaces concern such works, research of resistance of fuselages and tail opereny devices.

From the beginning of activity RIB became the centre of research works on aero- and hydrodynamics. It carried out of the task of Management VVF on comprehensive investigation of models of planes for Izhorskogozavoda, plane skis and screws of various types for the Moscow aerotechnical factory, wings and a hydroplan fuselage ' To ' for factory ' Dux '; carried investigations of the Moscow aviation and motor factories; has made the project of a wind tunnel for the Nikolaev physical observatory, spent tarirovku aerodynamic devices for the Kiev school of observers.
