Pneumatic Lift and Control Surface Technology for High Speed Civil Transports

摘要

Experimental evaluations have been conducted of blown high-lift devices and control surfaces applied to improve the low-speed terminal-area performance of generic High Speed Civil Transport (HSCT) aircraft. Plain blown flaps and advanced pneumatic high-lift devices have been integrated into highly swept vortex-dominated wings. These produced large lift increases, as well as significant drag reductions greater than full jet thrust recovery. Because conventional horizontal tails were inadequate to trim these configurations, blown canards were employed.
