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.
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.
English: Unofficial Combustion Scheme of the Raptor 1 rocket engine. Raptor 1 is a staged combustion, full-flow, methane-fueled rocket engine under development by Space Exploration Technologies Corp, and used for ground testing and in flight-test prototype rockets in 2018-2021.
The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [27] [28] 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.
