Peer Reviewed

Abstract: THE FLIGHT PROFILE of a mission in case of thrust failure prior to attainment of orbital speed is considered. Specifically the impact point corresponding to a given set of thrust cutoff conditions is analyzed. Analytical solutions are obtained for various impact parameters. Several graphical solutions are formulated for the purpose of generating such information, often referred to as the instantaneous impact point (HP) trace, for mission planning purposes. A new form of graph paper with trigonometric scales is introduced.
