in the field of remotely piloted vehicles (rpv's) greater emphasis has been placed on achieving combinations of higher altitude, longer endurance, greater payload capacity, and are more cost effective. To this end a light-weight, powerfull, compact, fuel efficient and inexpensive rotary propulsion engine development program is planned which would address itself to achieving the above emphasize combinations. Phase I would be the preliminary development work on the seals that provide sealing for the combustion chamber of the innovative rotary engine. The testing and carding of compression pressures and measurements of positional leak rates are planned. Stated otherwise, phase I would be the demonstration of the technical feasibility of the combustion chamber seals.
