Aug 3, 2024, 10:28 AM
SpaceX has unveiled the Raptor 3 engine, the latest iteration of its full-flow staged combustion engine designed to power the Starship. This new version boasts a record-breaking chamber pressure of 350 bar and generates a thrust of 269 tons, making it the most powerful methalox engine ever built. Raptor 3 incorporates significant design improvements, including regenerative cooling and secondary flow paths, which eliminate the need for a heat shield and fire suppression system. Elon Musk praised the Raptor 3 as 'truly a work of art,' emphasizing its lighter weight, increased thrust, and higher efficiency compared to Raptor 2. The development of Raptor 3 reflects SpaceX's commitment to innovation and optimization in rocket engine design, showcasing a significant evolution from its predecessors, Raptor 1 and Raptor 2, which produced 185 tons and 230 tons of thrust, respectively.
