Abstract: Physical Sciences Inc. proposes to develop and demonstrate a novel composite solid fuel for high performance ramjet and hybrid rocket applications. This new class of solid fuel will provide all the benefits of traditionally used solid ramjet fuels, while providing game changing advances in combustion efficiency, burning rates, and motor operating windows. Unlike other technologies, the proposed development does not rely on new chemical synthesis procedures or large concentrations of inorganic additives to provide high energy densities. Currently available, low cost materials are used, allowing for a low cost, low risk solution. In Phase I, the proposed investigation will focus on the development of critical components of the composite fuel system, and demonstrate propellant burning rates equivalent to liquefying solid fuels. Phase II will refine fuel formulations and validate their performance in sub-scale ramjet conditions. We envision this technology to enable new long-range solid ramjet missile and hybrid motor launch systems to be developed.
Benefits: The proposed composite solid fuel will enhance the properties of current composite solid fuel systems, improving ignition, combustion efficiency, and energy density characteristics. These benefits will lower required ramjet combustor size and inlet temperature, improving system performance. Applications include solid fuel ramjets and high performance hybrid rocket motors. This technology will therefore be of interest to multiple DoD agencies, as well as NASA and the commercial space launch industry. Patented technologies developed will also be of potential benefit for multifunction energetic material applications.
