ABSTRACT

The possibility of wind tunnel investigations of high-angles-of-attack aircraft dynamics using an actively controlled scaled model on three-degree-of-freedom gimbals is shown. A kinematics of the model motion on the gimbals is presented. Dynamic equations of motion are derived from the Lagrange equations. The stability and controllability of aircraft motion without a control system and with aerodynamics specified in a conventional table form are considered. The wing rock motion of the aircraft model at high angles of attack is investigated. Simulations of self-induced oscillations on the gimbals and in free flight are compared. The effects on the dynamics of the gimbal friction moments and shift of the center of gravity in the model relative to the center of the gimbals are considered.
