超音速旅客機の離陸上昇性能について ボルテックス・フラップの効果

Abstract

Improvements of the take-off and climb performance of the next generation supersonic transport (SST) are one of the key features for the SST development. Estimations of take-off and climb performance have been done to investigate the effect of leading-edge vortex flaps that can improve the low-speed aerodynamic characteristics of the SST main wing. Results show that the climb gradient of the SST is improved when the vortex flaps are deflected downward after lifting-off. The thrust required for the constant climb gradient can be reduced by the benefit of the vortex flaps.
