Endoatmospheric Energy Management Method for Launch Vehicle with Solid Rocket Boosters based on Changeable Launch Plane Strategy

Since the solid rocket boosters (SRB) can only be extinguished after fuel consumption, the energy management problem for the launch aircraft has received more and more attention nowadays. This paper comes up with a novel endoatmospheric energy management method based on the changeable launch plane (CLP) strategy for the SRB energy management problem. The transverse maneuvering energy management model is established. Based on the CLP theory, the height in the longitudinal plane and the displacement in the lateral plane are approximated by polynomial spline curves. The angle of attack (AOA) and the sideslip angle is calculated with the inverse of the dynamics subsequently. Finally, a simulation result for a three-stage solid rocket, called Vega, is given to demonstrate the effectiveness and efficiency of our proposed method. Compared with the traditional energy management method, our proposed method has a 75.86% improvement in the capacity of energy consumption.
