An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
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).
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 hybrid rocket engine uses a paraffin-based fuel and liquid oxygen. [10] On 4 September 2023 HyImpulse completed its ninth hot fire test campaign. With the successful completion of the testing, HyImpulse qualified its HyPLOX-75 hybrid rocket motor for flight. [11] The motor will be used aboard the SR75 and SL1 first and second stages.
The first [4] serious attempt to make a production air-augmented rocket was the Soviet Gnom rocket design, implemented by Decree 708-336 of the Soviet Ministers of 2 July 1958. More recently, about 2002, NASA has re-examined similar technology for the GTX program as part of an effort to develop SSTO spacecraft.

The main engine is a Polish construction which uses highly concentrated hydrogen peroxide as oxidiser. High test peroxide is produced in-house by the Institute of Aviation and has a concentration of 98%, offering increased specific impulse and density in comparison with the more commonly used 85-87.5% peroxide.
