Abstract

The paper presents a computer analysis for the determination of the wing twist. It is suitable for the calculation of the elastic and plastic angle of twist of straight wings. The wing twisting is assumed due to the action of aerodynamic and mass forces. The computer program is applied to L-29 advanced jet trainer for the calculation of wing twist.
