Static tests of a simulated upper surface blown jet-flap configuration utilizing a full-size turbofan engine

摘要

The investigation utilizing a small turbofan engine was conducted to evaluate static turning performance and pressure and temperature environment of an upper surface blown wing and flap segment. The tests involved modifications of the engine primary nozzle to alleviate high-temperature problems on the wing and flaps without adversely affecting static turning performance over the desired range of flap deflection and thrust condition.
