Investigation of Controllability Criteria of Unmaneuverable Aircraft Equippedwith a Side Stick

摘要

The main problems of non-maneuverable aircraft, equipped with a side controlstick are considered. The authors analyzed the literature data, conducted flight simulator investigations, performed a generalization of the available and obtained experimental data, conducted theoretical investigations and compared the obtained results with the flight test data and the data on specific aircraft. The experimental technique, adapted at TsAGI, with the use of the flight simulator FS-102 is described. The major characteristics of this simulator are presented, the side control sticks used in the experiment are described. A comparison of controllability of the aircraft equipped with side control sticks with the ones equipped with the conventional control levers is made. A theoretical approach to determine the optimum values of control lever loading and sensitivity characteristics is presented. The controllability criteria for selection of the characteristics are justified on the base on this approach and the obtained experimental data, the parameters of these criteria are concretized regarding side control stick application. The calculated estimation of optimum values of major control lever loading and sensitivity characteristic is carried out and a comparison of them and experimental data is made.
