Abstract

The paper presents an assessment of aircraft asymmetry parameters based on flight dynamics data (angular accelerations and velocities, linear accelerations measured in the body-fixed coordinate system) for subsequent elimination of the negative influence of asymmetry using a mass-inertial characteristics correction system. A method was proposed to determine the preferable approach for correcting asymmetry based on simulation of the aircraft motion, estimating the influence of each asymmetry parameter on the resulting angular acceleration. The possibility of correcting asymmetry by shifting the center of mass and by creating a corrective centrifugal moment of inertia through tilting a balancing weight is demonstrated. Relationships are derived linking the correctable asymmetry parameters with the aircraft motion parameters.
