Study on the non-Keplerian orbits of the near space hypersonic vehicles

This paper studied the bouncing trajectory of the near space hypersonic vehicles,and discussed the trajectory of the near space hypersonic vehicles that belongs to the category of non-Keplerian orbits.Firstly,its cruising phase dynamics equations,its reentry phase dynamics equations,and reentry-moment dynamics equations of non-Keplerian orbits were presented;next,and the question of the reentry-moment position vector of the near space hypersonic vehicles was researched;the concept of bouncing modulus was presented;lastly,the simulation was analyzed,the results was showed that the validity of dynamics equations of non-Keplerian orbits and the veracity of the bouncing modulus.Consequently demonstrates that the method of non-Keplerian orbits’ bouncing flight is a new valid approach of the near space hypersonic vehicles.
