Use Of Variable Incidence Angle For Glide Slope Control Of Autonomous Parafoils, Nathan Slegers, Eric Beyer, Mark Costello
Faculty Publications - Biomedical, Mechanical, and Civil Engineering
Strictly speaking, most autonomous parafoil and payload systems possess only lateral control, achieved by right and left parafoil brake deflection. An innovative technique to achieve direct longitudinal control through incidence angle changes is reported. Addition of this extra control channel requires simple rigging changes and an additional servoactuator. The ability of incidence angle to alter the glide slope of a parafoil and payload aircraft is demonstrated through a flight-test program with a microparafoil system. Results from the flight-test program are synthesized and integrated into a six degree-of-freedom simulation. The simulation model is subsequently used to assess the utility of glide …

Despite more than sixty years of engineering excellence, Rolls-Royce failed in its attempt to design and manufacture a radically new jet engine to meet contractual obligations with the Lockheed Corp. Consequently, both British and U.S. governments had to step in to avoid an unprecedented economic catastrophe.
