FIELD: aircraft engineering.
SUBSTANCE: proposed pilot seat is fitted at damping support. It comprises mechanisms of vibration exciters composed by loudspeaker. Sound waves of the latter act via membrane and extra mechanism to seat and pilot to activate the device by development of required characteristics of excited waves radiation in various bands of wave oscillation frequencies and amplitudes in compliance with aircraft actual flight conditions. Sound wave radiator is composed of a new subwoofer-type acoustic system with built-in amplifier. Said system is arranged in the box with outlet overlapped by extra rubber membrane. Subwoofer emitted acoustic waves act on tuber membrane for it to convert sound energy into mechanical power. Rod is secured by washers to membrane centre perpendicular to its plane. Membrane mechanical oscillations are transferred via the rod to aircraft standard seat and pilot.
EFFECT: simplified design, enhanced performances.
