Investigation of Controllability Criteria of Class III Aircraft Equipped with aSidestick

摘要

This work considers the controllability problems of Class III aircraft (large,heavy, low-to-medium maneuverability aircraft) equipped with sidestick controllers. This effort was done at TsAGI (Central Aerohydrodynamic Institute of Russia) in compliance with contract SPC-93-4046. The authors analyzed the existing data in the literature, conducted flight simulator investigations to generate new data, generalized the existing and new experimental data, conducted theoretical investigations, and compared these results with flight test data and data on specific aircraft. This report contrasts the controllability of aircraft equipped with sidestick controllers and those equipped with conventional controllers. It describes the experimental technique used with the FS-102 flight simulator, presents the major characteristics of this simulator, and describes the sidestick controllers used in the experiments. A theoretical approach determines the optimum values of sides tick loading and sensitivity characteristics. The controllability criteria to select these characteristics are justified based on this theoretical approach and obtained experimental data.
