Abstract

Abstract: Relationship between dynamic surface forces distribution of pilot body and flight load in maneuver flight was studied. Dynamic surface pressure and shear distribution of pilot body seated posture were expressed by setting up dynamic pressure factor and dynamic shear factor. Flight kinetic equations of pilot body seated posture were established. In the equations, relationship between pilot body inertia forces and dynamic surface forces were given, and the equations are square nonlinear for dynamic pressure factor and shear factor. Finally an example for climbing turn maneuver flight of some aircraft was done, dynamic surface forces distribution of pilot body were analyzed by numerical simulation, and the results meet the practical experience of pilot. The theory can be used to design and control the g-seat for flight dynamic simulation.
