Raptor is a family of rocket engines developed and manufactured by SpaceX. It is the third rocket engine in history designed with a full-flow staged combustion (FFSC) fuel cycle, and the first such engine to power a vehicle in flight. [15] The engine is powered by cryogenic liquid methane and liquid oxygen, a mixture known as methalox.
A new feature for the engine is the ability to throttle from 100% to 70%. [7] The engine's 150:1 thrust-to-weight ratio is the highest ever achieved for a rocket engine. [8] [9] The first flight of the Merlin 1D engine was also the maiden Falcon 9 v1.1 flight. [10]
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.
In 2017, he created a YouTube channel covering spaceflight education, and that became his primary occupation. [2] He also makes music, which has been used as background music for Rocket Lab launches. [9] After applying for the mission in 2022, Dodd was selected to participate in a lunar spaceflight as part of the dearMoon project crew. [10]
Worse, however, was the fact that the engine could not be throttled, and when the aircraft leveled off after its climb to altitude it quickly accelerated to speeds that caused serious compressibility issues. The RLM demanded that a version be developed with a throttle. HWK 109-509 A-1 Rocket Engine at Steven F. Udvar-Hazy Center Virginia, USA.
Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab [8] and manufactured in Long Beach, California. [9] The engine is used on the company's own rocket, Electron. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle.
The engine throttle range was 95–105%, the thrust vector control range was ±12° (project R-56) and ±8° for UR-700 rocket family. The oxidizer-to-fuel ratio was 2.67 and can be changed by up to 7%.
The rocket carries a scientific payload from NLR, which is a prototype IMU for the proposed future European SMILE launcher. [17] Additionally Stratos III has full 360 degree live stream downlink. At apogee the nosecone with payload separates from the oxidizer tank and propulsion system.
