The performance of solid fuel ramjet engines depends on both the heat of reaction and density of the fuel, which are essential factors for optimizing specific impulse and density-specific impulse. Density-specific impulse is calculated as the product of fuel composition density and specific impulse, reflecting not only fuel efficiency but also volumetric considerations that influence vehicle design and aerodynamics. This effect on design is particularly relevant for the lift-to-drag ratio (L/D), which plays a crucial role in overall vehicle efficiency. Specific impulse increases with the square root of flame temperature, while density-specific impulse improves linearly with fuel density. Enhancing fuel density through the addition of energetic particles and metal additives can optimize volumetric performance, while specific impulse benefits from additives like CuO and PTFE, which increase combustion temperature. This study aims to enhance density-specific impulse in ramjet fuels by introducing high-energy metals, including aluminum (Al), boron (B), and magnesium (Mg), into an HTPB-based fuel matrix, with CuO and PTFE added to increase specific impulse. The performance characteristics of these solid fuel compositions were evaluated using NASA’s CEA code, providing a detailed comparison of the compositions and their impact on ramjet performance. The findings offer valuable insights into fuel formulation strategies that enhance both density-specific impulse and overall combustion efficiency, supporting the development of optimized solid fuels for ramjet applications.
