DEVICE FOR INCREASING AND DEFLECTING THRUST OF JET-PROPULSION ENGINE OF V/STOL AIRCRAFT

摘要

In a vertical/short takeoff and landing (V/STOL) aircraft in which the exhaust gas from a jet-propulsion engine is discharged through an exhaust gas passage, secondary air induction passages (14, 14) are formed on the outer sides of the nozzle (12) for communicatively connecting the outside atmosphere to the upstream end of the exhaust gas passage (13), thereby to induct outside air as secondary air, into the exhaust gas passage (13) to be mixed with the exhaust gas.
Inlet flap gates (15, 15) are respectively provided at the inlet ends of the secondary air induction passages (14, 14).
A deflector device (22) is provided at the outlet part of the exhaust gas passage (13).
