Study of an Advanced Variable Cycle Diesel as Applied to an RPV (Remotely Piloted Vehicles)

摘要

A variable cycle diesel is examined for use in an unmanned long endurance RPV. Engine configuration studies are made and a possible installation arrangement developed. Installed performance projections are made and a long endurance RPV mission fuel, installed engine weight and propeller performance estimates made along with several aircraft installation drawings. It was found that the final engine configuration performed the specified mission with a total fuel and installed engine weight fraction of only 24 percent of the vehicle Take Off Gross Weight. The mission was evaluated at a cruise altitude of 65000 feet and an engine configuration suitable for use at 85000 feet was also investigated.
