A Description of a Pitch/Yaw Dynamic Stability, Forced-Oscillation Test Mechanism for Testing Lifting Configurations

Abstract

A forced-oscillation test mechanism for measuring the dynamic stability derivatives in pitch or yaw on lifting configurations has been developed at AEDC-VKF. The mechanism will support models with a combined loading up to 1200-lb normal force and 300-lb axial force. Wind tunnel verification tests were conducted on AGARD Calibration Models B and C and Model B body alone at Mach numbers of 2.5, 3.0, 3.5, and 4.0 and at angles of attack from -4.5 to 11.5 deg. A description of the apparatus, testing technique, data reduction equations (including effects of sting bending), and the results from the laboratory bench and wind tunnel tests are included. The results of these tests were in good agreement with previous experimental data and theory.
