Reverse hybrid rocket motor - posted in Newbie Questions: I've become interested in hybrid rocket motors lately (these use a liquid (or gas) and a solid as propulsive means- for example nitrous oxide and polypropylene). All of the hobbyist rockets I've found use a liquid or gaseous oxidizer with a solid fuel grain. While this is all well and good I'd like to try a reverse hybrid - with a solid ...

    Solid motors are simpler than hybrids, but do not offer for the controllability of a hybrid. For these reasons, hybrid rocket engines are an ideal platform for investigating rocket thrust. This research project encompassed the design, simulation, and testing of such a rocket engine. This topic involves experimental, theoretical, and numerical work in all areas related to design, novel fuel chemistry, enhancement of fuel and oxidizer performance and internal geometry requirements for liquid, solid, and gaseous fueled Hybrid and Bi-Propellant Rocket Systems for stable operation. A mix of commercial and bespoke software is used in the FDD. Hybrid rocket motor. Tier One uses a hybrid rocket motor supplied by SpaceDev, with solid hydroxyl-terminated polybutadiene (HTPB, or rubber) fuel and liquid nitrous oxide oxidizer. It generates 88 kN (20,000 lb f) of thrust, and can burn for about 87 s (1.45 min). The ability to understand and predict the expected internal behaviour of a given solid-propellant rocket motor under transient conditions is important. Research towards predicting and quantifying undesirable transient axial combustion instability symptoms necessitates a comprehensive numerical model for internal ballistic simulation under ... Simply by varying the speed at which the rod is driven into the engine, the researchers have shown that the engine can be throttled – a rare capability in a solid motor.
