On the Prediction of the Lateral/Directional Characteristics of Distributed Jet STOL Configurations.

Abstract

A method for estimating the lateral/directional stability characteristics of jet flap STOL transport configurations at high power-on lift coefficients is presented. In addition to inducing a large stabilizing sidewash at the vertical tail powered lift reduces the directional instability contribution of the wing/body, increases the wing body side force and tends to reduce (depending on the amount of geometric dihedral incorporated) the high level of effective dihedral normally associated with swept wings at high lift coefficients.
