Analytical parametric identification in dynamic wind-tunnel tests

The dynamic wind-tunnel tests of a functional model of a flight vehicle being developed make it possible to obtain more reliable data on aerodynamic and structural characteristics and, hence, improve the design quality and increase reliability in the finished product operation. The objective stated is achieved by formation of angular model motions, the parameters of which are measured and compared with angular parameters calculated using the analytical solutions of differential equations of motions being formed. We considered two media of the incoming flow with the resistance proportional to speed and the square of speed. The results can be used in flight vehicle design, development of onboard control algorithms and subsequent identification of other parameters. © Allerton Press, Inc. 2007.
