Especially for aerodynamic tests, TsAGI developed a new model of a wing with mechanized
During the tests, engineers tested the operation of the wing for takeoff and landing. Prior to that, the TsAGI had already tested the wing at high speeds.
TsAGI are developing aircraft with a fuselagedrop-shaped "Tadpole" from the beginning of 2010. Its strange form should increase the aerodynamic properties, which will allow speeds of up to thousands of kilometers per hour. The maximum flight range is up to 4.2 thousand km.
