Constant Volume Combustion Engine

To satisfy NASA requirements for a Mars Ascent Vehicle (MAV), C3 Propulsion has designed, built, and tested a Constant Volume (CV) combustion engine. This rocket engine is novel in that it applies a thermodynamic cycle unusual in rocketry applications. This CV engine can play a critical role in current NASA In-Space Propulsion Program. It was specifically designed for use with non-toxic, low temperature propellants. Its versatile multi-use capabilities for integrated main propulsion and reaction control, make it applicable for a broad range of missions. Other NASA applications would include lunarplanetary ascentdescent, integrated main propulsion and reaction control for orbital insertionmaneuvering, and return to Earth.Non-NASA applications include the potential for use on military platforms such as Kinetic Kill Vehicles (KKVs), as well as adaptation for commercial satellites using hypergolic propellants for orbital maneuvering and station keeping. Furthermore, C3 Propulsion will continue to leverage existing experience and expertise from its pool of technology partners at Aerojet, AMPAC-ISP, Lockheed-Martin, and their respective R&D efforts. Moreover, to increase its technology transition potential, C3 Propulsion works with business specialized in SBIR technology transition, like Vital Strategies, LLC. This ensures the alignment of small business inventiveness with industry technology gaps, as corporations make cost-effective responses to key national needs, as well as consumer needs. What is the need for a CV engine? Extensive trade studies on Mars Ascent Propulsion have been conducted. The results of a 2001 study indicated that a conventional two-stage solid would be the most promising and lowest risk for a Mars Sample Return mission. A subsequent study examined the trade between pressure fed vs. pump fed engines and reached the same conclusions obtained in previous studies. As long as conventional Constant Pressure (CP) engines cycles continue to be at the core of propulsion system trade studies, the result of any new study will not stray far from results obtained in the past. For non-traditional propellant systems to be competitive, there needs to be a fundamental change in the engine cycle as well, otherwise the optimum has already been identified. The Innovation Not only the CV engine has nearly identical specific impulse as the CP engine with the same mass flow and throat area, but also the nozzle optimizes at the same area ratio. Advantages of the CV combustion cycle over conventional liquid bi-propellant CP combustion cycles include the elimination of pumps and improved Isp for a given system supply pressure. This engine is not a pulse detonation engine, but an Adiabatic Isochoric Complete Combustion (AICC) engine. The advantages are the simplification of the ignition system, buffer gas injection, and a reduction in the extremely high pressures associated with PDEs. Specific advantages of the CV propulsion device for the MAV mission include: Light weight, low pressure fuel tanks High chamber pressure Meets martian temperature requirements without any form of active heating or stirring.

Missile Defense Interceptor

The 'Next Generation Aegis Missile' (NGAM) is a key component of the Obama administration's Phased Adaptive Approach for missile defense in Europe. The new interceptor will be designed to provide early intercept capability against some short range ballistic missiles, all medium range ballistic missiles, all intermediate range ballistic missiles and non-advanced intercontinental ballistic missiles. C3 Propulsion's team of chemists has demonstrated the feasibility of developing hypergolic fuel and oxidizer gelling agents based on ionic liquid chemistry. Our novel propellant formulations are the product of an evolutionary rather than a revolutionary approach. This solution increases density specific impulse, reduces cost and maintenance requirements, improves reliability and meets DoD Insensitive Munitions (IM) and safety objectives.

safety systems

The use of liquid hypergolic propellants presents a significant challenge for sea-basing under current Navy regulations since they are both toxic and an explosion hazard. Small propellant leaks that result in low airborne concentrations require a response that protects personnel by maintaining concentrations below the levels recommended by the National Institute of Occupational Safety and Health, especially in manned spaces. For larger leaks, it may not be possible to maintain these low concentrations. Under these circumstances, the purpose of the mitigation system is to prevent the build-up of explosive concentrations.

mitigation system

C3 Propulsion has designed, developed, and fabricated a system to enable safe storage, handling, transportation, and shipboard use of Liquid Hypergolic Propulsion (LHP) systems. The deployment of Liquid Hypergolic Propellants (LHP) for missile defense applications aboard surface ships and submarines, has not yet been approved by the US Navy Weapons Systems Explosive Safety Review Board (WSESRB). Moreover, limitations are imposed on shipping LHP systems by the US Air Force. The object of this Missile Defense Agency (MDA) sponsored project was to develop and demonstrate the feasibility of a system to contain and neutralize any potential hypergolic leaks, providing personnel protection, and preventing the build-up of an explosive concentration of propellant vapors. To this end, C3 Propulsion has integrated, within the MDA Systems Engineering Management Plan (SEMP), the technologies it has developed in the area of hypergolic propellant leak sensing and mitigation.

Power Generating Coverings

Improving current energy harvesting technology will enable the efficient capture andor conversion of acoustic, kinetic, and thermal energy. C3 propulsion has partnered with Wake Forest University to utilize their Organic ThermoElectric (OTE) example for space applications. The OTE example utilizes dispersions of nanowires in a polymer matrix. A large area fabric-like, heat collector (with modest efficiency) spread across an extended body heat source is able to collect as much or more power than a small highly efficient ceramic device where only limited contact is available with the body. This innovative technology can work either under typical ambient environments or under high intensity energy environments, as might be found in propulsion testing and launch facilities. Moreover, innovations in miniaturization and suitability for manufacturing of energy capture and conversion systems make this technology usable towards eventual powering of assorted sensors and IT systems on vehicles and infrastructures. High efficiency and reliability also consent its use in environments that may be remote andor hazardous, and having low maintenance requirements. Space Applications The generation of electrical power from thermal sources has extremely wide space applications: delivery of water to the vertical test stand for thermal and noise suppression for diesel engines supplement batteries for instrument and life support in manned space vehicles supplement instrument batteries in non-manned space vehicles supplement instrument airplanes batteries supplementeliminate batteries in experimental apparatus in R&D Centers. Other government applications The generation of electrical power has innumerable applications for DoD: Army and Marine Corps soldier fatigues to minimize the weight of batteries artillery barrels to minimize the weight for electronic gun controls vehicles to minimize battery requirements for electronics missile launchers to minimize batteries for launchers and guidance and control systems nuclear, biological, and chemical defense systems to minimize batteries radar and communications to minimize Navy micro and full sized submarines to minimize battery requirements surface ships to minimize battery and power generation requirements aircraft to minimize batteries for electronics and life support navy depots to minimize battery requirements.
