On 3 August 2019, Cape Rocketry launched JR101 in the Karoo, South Africa. An altitude of 10.3 km was reached, making it the highest verified altitude achieved in Africa by an amateur group. This was an especially notable achievement as the propellant was based on Ammonium Nitrate, as opposed to the more common ammonium perchlorate. All major ...
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 ...
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.
RS-68 being tested at NASA's Stennis Space Center Viking 5C rocket engine used on Ariane 1 through Ariane 4. A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket.
As the rocket moves through the atmosphere the air enters the front of the tube, where it is compressed via the ram effect. As it travels down the tube it is further compressed and mixed with the fuel-rich exhaust from the rocket engine, which heats the air much as a combustor would in a ramjet. In this way a fairly small rocket can be used to ...
The Stratos III rocket is 8.2 m tall and is powered by the DHX-400 Nimbus, a 360 kNs impulse hybrid rocket engine. [15] The DHX-400 Nimbus utilizes nitrous oxide as its oxidizer and a mixture of paraffin, sorbitol and aluminum powder for the fuel.
Pages in this category describe sounding rockets, carrier rockets or rocket stages rocket engines which use hybrid-propellant exclusively. This category does not include solid-fuel rockets used as missiles.
