The Ascent Trajectory Optimization of Two-Stage-To-Orbit Aerospace Plane Based on Pseudospectral Method

摘要：

　　Aerospace plane can fly in the Earths atmosphere with hypersonic and run in the low earth orbit.According to the tactical and technical index,by adjusting power,control,pneumatic components relating to trajectory optimization,we get the optimal ascent trajectory of minimal fuel consumption at a specific separation state(height 30km,Mach 6)with the Radau pseudospectral method.The terminal state can accurately meet the requirements of the ellipse orbit of height 300km.On the basis of optimal trajectory we need find the best separation condition.The relationship between the separation height,Mach number and fuel consumption is studied.The relationship between the flight path angle and the fuel consumption of the specific separation states is also researched.
