Small, Heavy Fuel, Compression Ignition Small UAV Engines

"Air Vehicles that are able to fly autonomously into confined spaces, land, shutdown, collect information, restart, and return to base, present an interesting propulsion challenge. Critical requirements of the propulsion system include:¿ Extremely high power per unit weight and per unit volume,¿ Extremely reliable, compact, and lightweight starting system¿ High fuel efficiency¿ Multi-Heavy Fuel CapableGSE has a scalable propulsion system that uniquely meets these challenges.Specifically, the GSE OAV propulsion system uniquely offers a system that: ¿ Will demonstrate scalability to all DARPA OAV program requirements¿ Is an Innovative, self-injected, high speed, compression ignition, 2-cycle engine design capable of operation on logistically available multi-fuels (i.e.: JP-5, JP-8, DF-2)¿ Utilizes counter-rotating propellers, eliminating torque and maximizing thrust efficiency, without the complexity of a gearbox.¿ Employs an innovative variable compression mechanism.¿ Incorporates high enrgy cartridge starting for extreme cold conditions.¿ Specific weight ratio approaching 1.5lbs/hp and 75hp/cu. ft of engine volume. Scalable to FCS program requirements. Applicable to the following government and commercial tasks:- Bridge inspection- Border/security patrols- Hazardous spill inspection- Fire surveillance- Crowd security- Pipeline/Power line Inspection- Film"
