Elevator Hinge moment studies over generic winged body configuration

摘要

Elevator hinge moment measurements have been carried out on a generic wing body configuration through wind tunneludtests. Tests have been carried out at subsonic and transonic Mach numbers in the angles of attack range -4° to 24°. Maximumudhinge moment coefficient occurs in the transonic region as expected. Positive deflections of elevator produce higher elevator hinge moment coefficient compared to that of negative deflections. Elevator hinge moment coefficient is linear with elevator deflection up to ±10° and angles of attack up to 10°.
