Abstract:

An investigation was conducted to validate the potential of a pneumatic thrust deflector based on circulation control technology. This thrust deflector concists of a small blown curved surface mounted adjacent to a two-dimensional nozzle. In the configuration evaluated, a 3.5-in. 8.9-cu -diameter blown surface was used to deflect the exhaust of a 660-lb 2.94-kN thrust turbojet. Thrust deflection through 65 deg was achieved at reduced thrust levels. This performance was achieved pneumatically without the use of complex moving mechanical parts.
