Microactuators for flight control

New concepts for micro-activated flight control are investigated for operation in both subsonic and supersonic flight regimes. A successful concept can provide an inexpensive flight control device with high frequency response and many control redundancies, and it can reduce size, weight, drag forces and energy consumption of the control system. Extensive preliminary work has indicated a delta wing of 3 mm base by 4 mm height, which can be deployed and activated at a location on the ogive of the projectile or at the beginning of its cylindrical afterbody can generate side forces of magnitude about 4 percent of the drag. During transient deployment of these micro activated delta wings the forces generated are expected to be higher than in a static operation and therefore they are more suitable for terminal flight path correction.
