Tests of a Linked Differential Flap System Designed to Minimize the Reduction in Effective Dihedral Caused by Power

Abstract

An investigation was made to determine experimentally the effects of a linked differential flap system upon the effective dihedral characteristics of a powered aircraft. The differential flap system consisted of two flaps so connected as to cause rolling moments automatically opposing those of slipstream effects. Results indicate that the negative dihedral changes caused by power may be reduced or eliminated by use of the differential flap system. Differential flaps also increased the static directional stability.
