Abstract

It is suggested to embed an elastic unilateral tie in control chain for turning an aircraft horizontal stabilizer. This elastic tie implemented as a support or a stretched only cable increases a critical flutter speed value for the stabilizer. A numerical solution are obtained for a case of non-linear aero elastic vibrations of the turned stabilizer. This solution shows significant increasing of the critical flutter speed right up to flutter elimination for some ranges of flight speeds and altitudes.
