A Fast-Reconstruction Algorithm for Aircraft Ascending Trajectory

During the aircraft ascending process,the actual orbit deviates from the orbit initially designed in the effect of uncertain disturbance.To settle the problem,the concept of fast-reconstruction of ascent trajectory is proposed,a new ascent trajectory can be gained by the fast-reconstruction without the newly trajectory optimization or design.And a fast-reconstruction algorithm for aircraft ascending trajectory based on the advance correction of the state value is detailed.Then,with the existence of the atmospheric disturbance,a fast-reconstruction simulation of the ascending trajectory is given by this algorithm.The simulation results indicate that the algorithm can take into account the state value restriction,terminal restriction,orbited accuracy,reconstructed time of the ascending flight,and the fast-reconstruction is realized,and moreover,the time of the fast-reconstruction is satisfied.
