SpaceX engineers perform first ignition test Booster 7’s steady fire, a prototype of the first stage too heavy. The test, in which only one of the booster’s 33 Raptor engines fired, brings the company closer to its first orbital test of the revolutionary Starship system.
The test was conducted on August 8 at SpaceX’s Starbase facility in Boca Chica, Texas. a tweet of the company Ground crew completed a single steady fire test of the Raptor engine, while the booster 69 meters high was standing on the launch tower”mekazillaBooster 7 is equipped with 33 Raptor engines, but SpaceX chose to fire just one in a rare moment of caution.
YouThe few spin-prime tests earlier in the day didn’t result in an explosion, thankfully. SpaceX prevented a repeat of the July 11 event in which a gaseous mixture of methane and oxygen accidentally ignited, causingThere was a loud bang just below the booster.
test of spin-primein which propellant is pumped through engines without igniting, usually done in preparation for static fire tests (static fire tests include igniting of the engine without the actual launch of the rocket). they are performed To test the pipeline, but the gases produced during testing from July 11 He was ignited by an unknown source. burst The resulting prototype booster was damaged and was sent back to the Starbase factory for repair.
After re-installing 20 of the rocket’s 33 Raptor engines, the booster returned to the launch pad on 7 Aug. Teslarati, On August 8, “apparently as a . SpaceX probe hints at more cautious second attempt at engine testingFrom Only one of those 20 Raptors, which is driving high-pressure gas through the engine, spins its turbopump without igniting its preburner (used to generate gas to power the turbopump). ) either main combustion chamber”, according to Teslarati.
same later day, SpaceX lit it Single Raptor engine. company have done before A static fire test of a prototype Starship booster, but it marks the first static fire test of Booster 7, even though it was in limited scale. The test was running smoothly, with the motor turning on and off after a four-second burn. And if that wasn’t enoughSpaceX too created Static fire test of two Raptors at a high level, viz.Prototype Starship 24.
It’s a small step for Starship, but potentially a huge leap forward for SpaceX as it works to develop its revolutionary heavy launch system. The booster is the first stage of a fully reusable two-stage rocket, with the Starship spacecraft as the upper stage. SpaceX envisions Starship as a platform for carrying passengers and cargo into deep space, including Future missions to Mars. It is also the current first choice from nasa Artemis 3, to serve as the manned landing system for the missionFromnot scheduled Not before 2025.
Both Starship stages are powered by Raptor engines, which are more powerful than the Merlin engines used in rockets. falcon 9 of the company Starship’s upper stage has already completed a series of sub-orbital tests, Involved a landingSuccessful vertical lift on May 5, 2021. A fully stacked system has yet to be launched, but SpaceX hopes to conduct an orbital test sometime this year., chief executive officer, Elon Musk, Hope this test will fail, and say So that a successful orbital test could happen sometime within the next 12 months.
The sight of a single Raptor engine running is impressive, so it’s hard to imagine what it will look like when all 33 Raptor engines are set to start mode. The successful test on August 8 shows that a full static test fire of Booster 7 is coming up.
