Rapid Assessment Tool for Space Access Vehicle Configurations in Guidance and Control Performance (Preprint)

摘要

A guidance and control (G/&C) design tool to rapidly assess the necessary control effort of a conceptual space access vehicle to track its flight trajectory is described. This tool can be used as part of the preliminary design cycle in configuration, trajectory planning, structural analysis, aerodynamic modeling, and control surface sizing. Given a conceptual configuration for a space access vehicle and a desired trajectory for a reentry flight, this G/&C tool provides an inner-loop feedback control law and outer loop feedback guidance law to track the given trajectory. Assessment of the vehicle's tracking performance and associated aero-control usage can be made. This assessment can then be used to determine the appropriate control.
