High performance solid fuels are important in hybrid rocket engines. Hybrids have been selected for low cost manned sub-orbital missions due to their relative safety. A high performance hybrid engine would be of great use to manned missions as well as low-cost launch solutions. Reducing the parts count and complexity will provide significant advantages for low cost launch solutions of nanosat payloads.
The technology of enhanced fuel grains was developed in response to a Navy need for high performance air-breathing ramjets. This proposal seeks to apply the same technology to hybrid rocket engines which are similar in nature. This technology will impact the development of low cost launch vehicles by providing a high performance and simple alternative to more complex and costly systems such as liquid rocket engines.
