Book Synopsis A Wind-tunnel Test Technique for Measuring the Dynamic Rotary Stability Derivatives Including the Cross Derivatives at High Mach Numbers by : Benjamin H. Beam
Book excerpt: A method is described for measuring the dynamic stability derivatives of a model airplane in a wind tunnel. The characteristics features of this system are that single-degree-of-freedom oscillations were used to obtain combinations of rolling, yawing, and pitching motions; that the oscillations were excited and controlled by velocity feedback which permitted operation under conditions unfavorable for more conventional types of oscillatory testing; and that data processing was greatly simplified by using analog computer elements in the strain-gage circuitry.
