Paraffin-Based Hybrid Rocket at NASA Ames
“NASA/ARC Peregrine Project has a requirement for Paraffin-based fuel grains (14.5 inch nominal diameter) to be used in combustion tests at N249. Fuel additives are of great interest that can increase the specific impulse of the rocket motor to be useful in an actual hybrid rocket motor, many properties of the additive alone and in combination with the fuel must be investigated. A useful additive is one that is dense, chemically stable, improves the performance and/or structural characteristics of the fuel, and is nontoxic and relatively inexpensive when produced in large quantity.” More.
