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 ...
Hybrid rocket propulsion system conceptual overview. In its simplest form, a hybrid rocket consists of a pressure vessel (tank) containing the liquid oxidizer, the combustion chamber containing the solid propellant, and a mechanical device separating the two. When thrust is desired, a suitable ignition source is introduced in the combustion ...
The Scaled Composites Model 316, [2] known as SpaceShipOne, was a spaceplane designed to: Carry three humans (one of them a pilot) in a sea-level pressurized cabin. Be propelled by rocket from an altitude of 15 km (9.3 mi) to in excess of 100 km (62 mi). Reenter atmosphere and shed kinetic energy in an aerodynamically stable configuration.
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 ...
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.
All of these characteristics lead to kerosene / hydrogen peroxide engines being simpler and more reliable to construct than other liquid propellant chemistries. Gamma had a remarkably reliable service record for a rocket engine. Of the 22 Black Knight and 4 Black Arrow launchers, involving 128 Gamma engines, there were no engine failures. [14]
The development and testing of TM65 was restarted in 2012 to explore if it was a viable replacement for the hybrid engine that Copenhagen Suborbitals previously had favored. Construction of the first prototype TM65 engine was completed in the spring of 2012 and successfully test fired in May 2012. [ 6 ]
The RD-250 (Russian: Ракетный Двигатель-250, romanized: Raketnyy Dvigatel-250, lit. 'Rocket Engine 250', GRAU index: 8D518) is the base version of a dual-nozzle family of liquid-fuel rocket engines, burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide (N 2 O 4) oxidizer in a gas-generator open cycle.
