Abstract
The invention is a wind tunnel suspension system for testing flutter models under various loads and at various angles of attack. The invention comprises a mounting bracket assembly 10 affixing the suspension system to the wind tunnel, a drag-link assembly 20 and a compound spring arrangement. The compound spring arrangement comprises plunge spring 18 working in opposition to compressive spring 17 so as to provide a high stiffness to trim out steady state loads and simultaneously a low stiffness to dynamic loads. By this arrangement an airfoil 25 may be tested for oscillatory response in both plunge and pitch modes while being held under high lifting loads in a wind tunnel.
