POWER PLANT OF FLYING VEHICLE WITH LAMINAR-FLOW CONTROL SYSTEM OF AERODYNAMIC SURFACES Russian patent published in 1997 - IPC

FIELD: manufacture of flying vehicles and power plants. SUBSTANCE: aerodynamic surfaces of flying vehicles are provided with air suction slots connected with compressor of laminar-flow control system. Air being sucked is included in thermodynamic cycle of main engines of flying vehicle. Engine has inner loop including the compressor, combustion chamber and turbine and auxiliary loop including the head exchanger, compressor, combustion chamber and turbine. Air from inner loop is bled to auxiliary loop after the compressor of inner loop through pipe line connected to heat exchanger. Part of air bled from auxiliary loop after compressor of this loop is expanded in power turbine after preheating it in additional combustion chamber. Power turbine is mounted on common shaft together with compressor of laminar-flow control system. After expansion gas is directed to combustion chamber of internal loop. Gas from turbine of auxiliary loop is returned to the same combustion chamber. EFFECT: optimal combination of capabilities of flying vehicle and its power plant. 2 dwg
