Device for simulating the aerodynamic forces applied on two orientable aerodynamic surfaces of a vehicle such as a missile

摘要

The appts. is intended to simulate the aerodynamic forces applied to an aerodyne component due to the lift and turning effects during motion. Two steering surfaces (12) which are fastened to the body of the aerodyne (10) are each attached to anchorage devices (16) arranged to apply tension to the surfaces. The anchorage devices are able to vary the applied tension, applying an adjustable force to simulate the varying lift experienced by the surface. Two further systems (28) are able to provide a variable resistance to the forces, simulating the effect of the aerodyne in flight.
