Topics of Research and Main Results

Static deformation effect on the orientation changing of various airframes parts relatively to the approach flow.

Effect of dynamic deformation of airframe on the flight characteristics. The calculation methods of the modified derived aerodynamic forces and moments, considering the local variation of the angle of attack because of the elastic deformation of wing, fuselage and tail assembly and the elasticity calculation in case of stability and control characteristics determination, are developed.

The calculation methods of airframe deformation for the calculation of the dynamic stability characteristics in the conditions of atmosphere turbulence effect are developed.

The methods of determination of the airframe elasticity effect on the flight safety and comfort are offered.
