The article simulates the dynamics of the design of a solar sail, made in the form of two light-reflecting tapes, the surface of which is formed by centrifugal forces. The spacecraft is in a circular Earth orbit at an altitude of 400 km, where the atmospheric density is sufficiently high to affect the dynamics of the thin-film structure. The spacecraft “Sail-MSTU” is considered as the object of study. A specific case of impact is considered when the direction of the velocity pressure coincides with the axis of rotation of the satellite. The simulation was carried out in the MSC Adams program, where the sail blades were represented as multi-link mechanisms. As a result of the simulation, the amplitude of the sail oscillations along the direction of the incident flow and the amplitude of the angular velocity oscillations of the satellite were obtained.
