Multi-effectors distribution of flying wing with stealthy optimization

With regard to the objective of stealthy optimization in control surface deflection, the stealth-based multi-effectors distribution scheme is presented for flying wing in this paper. The radar cross section (RCS) of each control surface is calculated and analyzed. The stealthy efficiency data curves are obtained through comparing the deflection values with the normal state. Taking the objective of optimal stealthy performance into account, the weighted pseudo-inverse is achieved by equivalence transformation. Furthermore, the sequential quadratic programming (SQP) based control allocation is applied to get rid of actuator constraints. To validate the effectiveness of the proposed approach, the simulation on the flying wing indicates that the stealthy generated by control surfaces can be minimized by reasonable deflections.
