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 ...
English: An analysis of the Raptor 2 full flow stage combustion cycle. Data from Elon Musk and SpaceX were combined with engineering analysis and reasonable assumptions to estimate engine parameters shown on this diagram.
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.
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine-engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
