Abstract
A method of formation of test signals is proposed for studying the aerodynamic characteristics of flying vehicles with the use of the technology of freely flying dynamically similar models. Simultaneous excitation of all input channels in a prescribed frequency band by a set of mutually orthogonal signals is applied to increase the efficiency. A modified method of calculating the set of mutually orthogonal sinusoidal signals with a small normalized peak factor is presented. Results of simulating the motion of a flying vehicle in the MATLAB/Simulink environment with the use of the developed method of test signal formation are reported.
