The Question of Spontaneous Wing Oscillations : Determination of Critical Velocity Through Flight-oscillation Tests
This is a 1936 NASA technical report, issued through the NASA Technical Reports Server, on whether wings oscillate spontaneously and how to find the critical flutter velocity from flight-oscillation tests. The pictures are engineering diagrams of deflection and resonance curves plotted against load, frequency and velocity, plus a photograph of a model wing mounted in a wind tunnel, so they suit a designer wanting technical line graphs, resonance-peak charts or a wind-tunnel setup scene.
