A NASA employee standing between two Raptor 2 Vacuum engines (background) and a Raptor 2 sea-level (foreground). The streamlined design is due to the reduced parts visible above the engine nozzles. Raptor 2 is a complete redesign of the Raptor 1 engine. [79] The turbomachinery, chamber, nozzle, and electronics were all redesigned.
Raptor is a family of methane/liquid oxygen rocket engines under development by SpaceX since the late 2000s, [2] although LH2/LOX propellant mix was originally under study when the Raptor concept development work began in 2009. [15] When first mentioned by SpaceX in 2009, the term "Raptor" was applied exclusively to an upper stage engine ...
The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [ 24 ] [ 25 ] Before 2014, only two full-flow staged-combustion rocket engine designs had advanced enough to undergo testing: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne Integrated Powerhead Demonstrator in the mid-2000s. [ 26 ]
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.
The non-cryogenic N 2 O 4 /UDMH engine RD-253 using staged combustion was developed by Valentin Glushko circa 1963 for the Proton rocket. After the abandonment of the N1, Kuznetsov was ordered to destroy the NK-33 technology, but instead he warehoused dozens of the engines. In the 1990s, Aerojet was contacted and eventually visited Kuznetsov's ...
[1] [2] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability. The F119 is also the basis for the Joint Strike Fighter (JSF) propulsion system, with variants powering both the Boeing X-32 and Lockheed Martin X-35 concept demonstrators.
Stiga distributes and sells its products in over 70 countries around the world. Stiga was originally a Swedish brand known for the production and distribution of lawnmowers, a wide range of motorized garden tools, snowmakers, and table tennis products and table hockey games. In the year 2000, Stiga was acquired by Castelgarden SpA via a merger ...
