Taschenbuch. Zustand: Neu. Neuware - The purpose of this research was to parametrically investigate the viability of skip entry maneuvers as an alternative to vacuum-only maneuvers, and to identify whether skip entry maneuvers can extend spacecraft mission lifetime by limiting propellant expenditure through the exploitation of t…he aerodynamic interaction between the upper atmosphere and an example entry vehicle and remote-sensing orbital platform. Employing the X-37B Orbital Test Vehicle (OTV) and a notional satellite design as the example entry vehicles, the entry profile dynamics of a skip entry maneuver were characterized with varying trajectory initial conditions such as entry altitude, entry flight-path angle, and vehicle aerodynamics. In addition, the requirements of skip entry maneuvers were characterized, specifically the required to complete one or more successive skip entry trajectories as well as to execute a desired change in orbit inclination angle.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
