Abstract:

In order to provide a means for accurate in-flight simulation of VSTOL aircraft, a computer model technique has been adapted to a variable-stability helicopter. Unlike the stability-derivative simulation technique, which is usually employed in variable-stability aircraft, the model approach produces a response which is essentially independent of the dynamics of the test vehicle. The aircraft response, therefore, is a function only of the evaluation pilots control inputs and the dynamics which are programed into the analog computing equipment. In-flight time histories of the helicopter response and the corresponding commanded response are presented to illustrate the effectiveness of the technique. The results indicate that the model technique does, in fact, provide a feasible, accurate, and flexible approach to in-flight simulation. The Report is one of the series 515-522 of papers presented at the Twenty-Seventh Meeting of the AGARD Flight Mechanics Panel, held 11-22 October 1965 in Rome, Italy. Author
