The first work on hybrid rockets was performed in the early 1930s at the Soviet Group for the Study of Reactive Motion. Mikhail Klavdievich Tikhonravov, who would later supervise the design of Sputnik I and the Luna programme, was responsible for the first hybrid propelled rocket launch, the GIRD-9, on 17 August 1933, which reached an altitude of 400 metres (1,300 ft).
Hybrid rocket fuel regression refers to the process by which the fuel grain of a hybrid-propellant rocket is converted from a solid to a gas that is combusted. It encompasses the regression rate, the distance that the fuel surface recedes over a given time, as well as the burn area, the surface area that is being eroded at a given moment.
RocketMotorTwo is a hybrid rocket engine utilizing solid hydroxyl-terminated polybutadiene (HTPB) fuel and liquid nitrous oxide oxidizer – sometimes referred to as an N 2 O/HTPB motor [8] [9] – providing 70,000 pounds-force (310 kN) of thrust. [10] The design makes use of lessons learned during the development of the SpaceShipOne hybrid ...
The number of members has increased to over 190 in 2020. Over the years DARE has developed expertise in all three major rocket propulsion technologies (solid, liquid, and hybrid), with multiple conference papers published each year. 2009 marked DARE's Stratos I launch, which set the European altitude record of 12.5 km for student rockets.
SABRE (Synergetic Air Breathing Rocket Engine [4]) was a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air-breathing rocket engine. [ 5 ] [ 6 ] The engine is designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon spaceplane to low Earth orbit.

The propellant used in a rocket engine plays an important role in both engine design and in design of the launch vehicle and related ground equipment to service the vehicle. Weight, energy density, cost, toxicity, risk of explosions, and other problems make it important for engineers to design rockets with appropriate propellants. The major ...
HyImpulse is a German private space launch enterprise headquartered in Neuenstadt am Kocher and developing a small launch vehicle designed around hybrid-propellant rockets. The company is a DLR spinoff founded in 2018 out of the chemical propulsion center of the German space agency's Lampoldshausen facility. [1]
