A New Guidance Algorithm for a Powered Ram Air Parafoil System under Wind

摘要

In this paper a new guidance algorithm for a powered ram air parafoil under wind is considered. After analyzing 6 DOF and 9 DOF nonlinear dynamic models of the parafoil system, wind effect is added to them. In order to keep the vehicle on the desired flight path an effective guidance algorithm using estimated wind information is proposed. After a Hardware-In-the-Loop Simulation (HILS) study, flight tests are performed to evaluate the new guidance algorithm under real wind.
