PROPOSAL #: A4.02-9234 (For NASA Use Only - Chron: 012765 )
PROPOSAL TITLE: Powerplant Which Transitions Automatically to Ramjet Operation

Cottrill Cyclodyne Corporation's 'Cyclodyne' powerplant design combines an efficient ramjet design with a simple static-running concept, and provides a gradual transition from static-running operational mode to a reasonably efficient subsonic ramjet mode as forward velocity is increased over a practically attainable range. High affordability is a primary claim; a reasonable goal is total cost of ownership reduced to half that of equivalent turbocompressor designs, over the life of the engine. Other claims of interest are:
(1) complete absence of internal moving parts for powerplant operation;
(2) complete absence of pumped lubricants;
(3) extremely low cost to manufacture, due to absence of any high speed balancing and high-precision machining requirements, overall mechanical simplicity, and no structural use of exotic materials;
(4) extremely low ongoing maintenance, due to overall mechanical simplicity;
(5) very low engine weight and high thrust-to-weight ratio (at normal flight speeds);
(6) practically instantaneous power output response to throttle changes;
(7) efficient operation with a wide variety of cheap liquid fuels and, eventually, the possibility of the use of pure gaseous hydrogen as a non-polluting alternative fuel.

Potential commercial applications of Cottrill Cyclodyne Corporation's 'Cyclodyne' powerplant design include, but are not limited to:
(1) Full-scale experimental aircraft builders (probably the best first choice for rapid penetration of an existing market);
(2) Private civil aviation (high potential impact on industry revitilization);
(3) Small commercial civil aviation - business jet craft, etc.;
(4) Airline transport civil aviation (with major upward re-scaling of the design);
(5) Military aviation, including combat aircraft (with major re-scaling);
(6) Unmanned flight programs - target drones, surveillance, weather research, etc.;
(7) Scale and speed model aircraft hobbyists (with downward re-scaling - reduction in thermal efficiency is to be expected);
(8) Non-aviation and non-vehicular uses - turbine drives, pelletized solid fuel combustors, etc. (with ramjet section omitted, static-running section should be at least as efficient as commonly used combustor types).
