This is, in fact, an example of rocket propulsion: the idea of propelling a vessel forwards by ejecting part of its mass in the opposite direction that we want to travel. The test culminated the Hypersonic Upgrade Program (HUP) which began in 1998. Rockets designed for interplanetary flight need to supply both a fuel and an oxidant for their propulsion, and the ratio of the two has to be exactly right for maximum propulsion and minimum mass. Acceleration depends on the exhaust velocity, burning of the fuel, and mass of the rocket. “Rotorcraft Propulsion Performance and Qualification Requirements and Guidelines for Rotorcraft Drive Systems.
