Net lifts of modern mechanical auxiliary high-lift systems and blown flaps are compared, as used on STOL aircraft with high surface loads. The possibilities for achieving aerodynamic efficiencies with these high-lift systems are discussed. Aerody-namic system problems and the effects of system weights of different auxiliary high-lift devices on net lift are considered. The net lifts of complex mechanical and blown-flap systems are determined as applied to a STOL aircraft configuration based on a surface loads of 370 kilograms per square meter for which a maximum lift coefficient of about 3.5 is required in the trimmed state. It is found that mechanical high-lift systems are superior to blown flaps in this comparison. (Author)
