Low-speed aerodynamics of the upper-surface blown jet flapReview of the results of recent wind-tunnel investigations conducted to provide fundamental aerodynamic information on the upper-surface blown jet-flap concept incorporating high-bypass-ratio turbofan engines. The results of the investigations have shown the concept to have aerodynamic performance generally comparable to that of other externally blown high-lift systems. Some of the more critical problem areas associated with this concept are covered, and solutions which have been found for these problems are discussed.
