Pursuant to the work order, Cyclone will be developing preliminary designs, specifications and test parameters on a compact 10 hp (7.5 kW) external combustion engine for use in various power applications.
The proposed Cyclone engine would be designed to run on both traditional fuels and a monopropellant called Moden Fuel, which can combust in the absence of oxygen. (Moden Fuel was originally developed by James R. Moden, Inc. to power US Navy torpedoes.)
In October 2009, Cyclone completed its first-phase Independent Research and Development contract for Raytheon IDS, which involved performing certain load-based dynamometer tests on the Mark II Engine, and also running the engine on Moden Fuel. The results from these tests were reviewed and validated at the time by Raytheon IDS, a business of Raytheon Company.
