Aerospace Instrument-Making Annotation << Back Estimation of the technical possibility of the operated lowering of the cosmic module in thick layer of atmosphere with main rotor in autorotation regime B.L. Artamonov, G.V. Malyshev The problem is considered about braking of the returned module of the cosmic aircraft with main rotor. It is required value, is able main rotor of the assigned diameter to create in autorotation regime such holding up effort, which completely goes out the initial velocity of the reduction of the aircrafts and will provide his soft landing on surface of the Land.
