DEVICE FOR GAS-DYNAMIC BLOW OF CONTROL SURFACE OF FLYING VEHICLE

摘要

FIELD: gas-dynamic blow of control surfaces of flying vehicles. SUBSTANCE: device includes engine, air intake passage, engine exhaust gas duct and control surface; jet pipe of engine is used as duct for supply of exhaust gases to control surface. Near this surface, duct has form of profiled attachment; provision is made for supply of air to jet pipe at temperature considerably below that of exhaust gases of engine. Device may operate at take-off mode of aircraft and at cruise mode of flight. Such construction of device enhanced its efficiency due to additional blow of control surface, thus creating lift force and consequently control moment. EFFECT: enhanced efficiency; reduced mass of control surface due to combination of engine jet pipe and duct feeding exhaust gases to control surface. 3 dwg
