Dynamic stability of parabolic shells in a supersonic gas flow

Applied hydromechanics, Vol. 16 (88) ¹ 4, (2014) p.3-10
Dynamic instability of parabolic covers in a supersonic gas stream is investigated. Such designs describe a rockets deflectors. The method of the set forms is applied to receiving the equations of movement of a design. The supersonic current of gas is described by the piston theory. Areas of dynamic instability of a design and form of dynamic loss of stability of parabolic covers are investigated at emergence of self-oscillations.
KEY WORDS:
