Continuous Constant Thrust Maneuver in Polar Coordinate System
摘要
Abstract
Continuous constant thrust is very important in orbital maneuver and escape flight.Small thrust maneuvers are fit for spacecraft rendezvous,and the tangential(or circumferential)thrust and radial highthrust can be applied in escaping from the earth's gravitational field.By using the equations of motion in polar coordinate system for constant thrust,there iS no limit on the thrust level and no restraints on the relative distance.Orbital radius and velocity can be directly obtained as functions of time or polar angle,which is helpful for design of flight mission and motion trajectory.Especially,when the initial orbit is circular,for small thrust and short flight time,approximate analytic solutions can be derived from non-dimension form of the motion equations.Some interesting results and application cases are given,which are useful for engineering applications.关键词
