Aerodynamic research laboratory. The project of the aeromechanical centre

So, even prior to the beginning of war by a wind tunnel the Officer aeronautic school headed by the major general A. of M.Kovanko had. In 1909-12гг. Here by order of A.M. Kovanko seven planes of various designs from which only one successfully flied have been designed and constructed.

With the war beginning at the Central scientific and technical laboratory of the Military man ministerstvabylo the aeronautic branch in which the big wind tunnel was used is created.

Attempt to create one more large aerodynamic centre has been undertaken at the Petersburg institute of engineers of means of communication. Here in the end of 1909 the small aeromechanical laboratory for maintenance of a course of the aeronautics read at institute by professor N. A.Ryninym, demonstration of corresponding experiments has been organised. Since 1911 in it some research works in a small wind tunnel (by section 0,5x0,5 by definition of factors of resistance of bodies of the various form and an aerodynamic spectrum of an air stream, on carrying out of purges of models of hangars, trains, bridges, snow protection, and also planes and dirigible balloons were spent also. Poslespetsialnoj of foreign business trip in the spring of 1911 of N.A.Rynin has developed the project of the aeromechanical centre with the big wind tunnel in diameter of 2,2 m which realisation was prevented by war. With its beginning in laboratory the infirmary has been developed.
