Abstract: With the development of aeroassist technology, either for near-earth operations or for planetary aero-capture, it is of interest to have accurate analytic solutions for the speed, flight path angle and altitude during the atmospheric passage.For a future aerospace plane which uses the accumulated kinetic energy to glide for a long range, explicit relations among the main state variables are also useful for guidance purposes.In this paper we have used normalization to put the equations of motion for planar entry around a non-rotating planet into a form which is suitable for an analytic integration.Explicit and accurate solutions are then obtained for ballistic fly-through trajectories, lifting skip trajectories and equilibrium glide trajectories.With the development of aeroassist technology, either for near-earth orbital transfer or for planetary aero-capture, it is of interest to have accurate analytic solutions for reentry trajectories.In this paper, it is proposed to obtain the relationships between the altitude, speed, flight path angle and distance traveled during entry for the three typical entry modes.
