WIND-TUNNEL AERODYNAMICS IN ROTARY TESTS OF COMBAT AIRCRAFT MODELS

To predict the full-scale aerodynamics of a combat aircraft performing high-alpha maneuvers requires the combined usage of experimental and theoretical tools. The preferred experimental tool is the rotary rig b ecause it provides simulation of one important component of advanced m aneuvers, i,e., the velocity vector roll. The present paper analyzes t he results obtained in the recently completed investigation by AGARD F DP Working Group 16. Anomalous results are obtained when attempting to simulate high-Reynolds-number rotary characteristics in subscale test s using boundary-layer trips alone or in combination with forebody str akes.
