Abstract

An experimental study of single-engine canard aircraft interactive behaviors between vectoring jet and ground effect is conducted in the low-speed wind tunnel. The results indicate that jets can enhance the ground effect of the aircraft, increase the lift coefficient, reduce flight velocity of take-off/landing, and shorten the distance of take-off/landing, improving the performance of take-off/landing. When the nozzle of vectoring engine is deflected upward or downward, the airflows induced by vectoring jets in the upper and lower surface of the aircraft are asymmetrical, reducing the increments of drag coefficient caused by ground effect. On this basis, the flow field mechanism of interactive behaviors between vectoring jet and ground effect is analyzed by numerical simulation.
