Since winged space vehicles perform unpowered hypersonic reentry flights at very high angle of attack avoiding excessive heat loads, the lateral directional stability and controllability are the critical aerodynamic design subjects to accomplish desired trajectory and to meet cross range requirements. The lateral stability and controllability criteria is reviewed, and analytical considerations are presented on the lateral control divergence mechanism using linear transfer function method. It is shown that the zero loci of the multiloop control transfer function indicate the stability of the bank angle control with rudder coordination and has equivalent meaning to the lateral control divergence parameter. A synthesis of simple lateral multiloop controller is proposed for practical application of the reentry vehicles flying at very high angle of attack.
