HELICON CHEMICAL COMPANY LLC — Department of Defense SBIR Phase I: MDA18-004

Description

Future MDA interceptors require advanced propulsion capabilities, with higher performance in smaller, volume-constrained systems. Innovative propellant chemistry is needed to enable substantially greater performance in smaller packages. One factor limiting the maximum performance achievable in modern propellants is the slow ignition and combustion of the propellant’s metal fuel particles, typically aluminum. Problems due to the slow reaction of aluminum are exacerbated in small rocket motors. Incomplete aluminum combustion due to short residence time in small combustors causes significant performance loss. Therefore, the theoretical maximum performance of metal-loaded fuels is unattainable with existing technology. Helicon has developed a new class of polymer-bonded aluminum fuels to dramatically increase the specific impulse and burning rate capabilities of future propellants. Helicon’s technology fundamentally transforms the aluminum combustion mechanism. Using a novel, scalable in situ nanocomposite synthesis process, Helicon produces high-energy composites with near-molecular-level intermixing of the aluminum fuel and polymer binders, such as HTPB. For the Phase I project, Helicon will formulate propellants, measure burning rates, and perform rocket motor static fire tests to demonstrate improvements in specific impulse and burning rate compared to relevant baselines.
