超音速旅客機の離陸上昇性能について―前縁ボルテックス・フラップと後縁フラップの併用―

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. Take-off and climb performances have been estimated for the cranked-arrow-wing SST configuration when the leading-edge vortex flaps and the trailing-edge flaps are deflected. Results show that the take-off distance and the balanced field length are reduced when the trailing-edge flaps are deflected, as expected. The thrust required for the constant climb gradient can be reduced when the leading-edge vortex flaps and the trailing-edge flaps are deflected at the same time.
