N2 - According to the strict aerodynamic heating environment in the reentry process, a new reentry trajectory planning method is presented. A reasonable Heat Flux Rate (HFR) curve is designed with the energy of the aircraft, and the real-time instruction of the Angle of Attack (AOA) is decoded. Then, the flight corridor is planned by the multi-constraint conditions. After that, the flight trajectory could be optimized through applying the pseudo-spectral method. At last, the simulation experiment under Matlab is carried out with an example lifting flight. The results show that the aircraft's total heat absorption (THA), which got through the new planning method, is smaller than that by the traditional method.
