FIELD: aeronautical engineering; programmed control of twin pulsejet engine. SUBSTANCE: straight-flow chamber of nose portion of engine contains mechanical oscillating loop made in form of adapting type gas-dynamic pendulum which is just section of wing assembled from two elastodeformable S-shaped side members and articulated in nose portion. Straight-flow chamber is rectangular in section nose portion of pendulum is directed towards gas-air flow. At outlet, chamber is divided in two passages narrowing towards periphery; these passages are connected with combustion chambers of pulsejet engine. Aft part of pendulum is used for control of gas-air flow escaping from engine combustion chamber according to harmonic law. EFFECT: enhanced efficiency. 3 cl, 9 dwg
