ABSTRACT:
This invention is a wind tunnel model mount system (10) for effectively and accurately determining the effects of angle of attack and airstream velocity on a model airfoil or aircraft. The model mount system includes a rigid model (30) attached to a splitter plate (11) which is supported away from the wind tunnel wall (20) by a plurality of flexible rods (12). Conventional instrumentation (21) is employed to effect model rotation through turntable (13) and to record model (30) flutter data as a function of the angle of attack versus dynamic pressure.
