Granville has designed a new satellite/spacecraft propulsion engine, GREP, delivering over 100.mN/1.0 kW of force from strong electromagnetic energy… more force magnitude and efficiency than existing propellant limited ion thrusters. And, because it uses renewable power from on-board solar/electric panels, GREP offers extended propulsion maneuver life, up to 15 years or more, substantially longer than existing mass and volume limited chemical reaction propulsion engines. GREP, although electromagnetic, is subject to Newton’s 3rd Law: for every action there is an equal and opposite reaction. However, there is a new Granville insight into Newton 3 enabling GREP. That is, electromagnetic energy, processed by modern electronic circuits, can generate interactions within the engine chamber to yield the normal action energy, and … with the reaction energy dependent on certain chamber setup electrical/mechanical values, the reaction energy becomes equal and parallel to the action energy, and thus propulsive, and not the usual equal and opposite non-propulsive reaction. GREP was peer reviewed by a west coast physics professor, by two east coast EE professors, and by two government propulsion PhD’s. No flaws were found. Thus, we propose in Phase 1 to finalize/assemble the hardware, and in Phase 2 to test, Demo, and improve the system.
