First SpaceX spacecraft engine suffers from "anticipated" damage during Raptor testing.



CEO SpaceX Elon Mask says that the first full-scale Star Ship engine that will be tested has already been pushed to the site less than three weeks after the start of the campaign, setting the scene for the second full-scale Raptor to take on

Musk's words, while most of the damaged Raptor path components still need to be easily reused, the second completed engine compilation is "virtually complete," and that Raptor will assume speed testing rather than waiting for the repair of the first engine. This is undoubtedly an extremely aggressive test program, especially for such a new and up-to-date missile system, but these latest developments are ultimately much more encouraging than they are.

Although the seven engines of the Raptor Integrated Subcale static fires the way back in September 2016, Spacex's propulsion team completed Raptor's basic project and completed the collection, shipment, and integrated static fire of the first full-size engine on February 3, significantly less than three weeks before Musk took to Twitter. In addition to confirming that the new Raptor was damaged during its last static fire a few days before, Musk showed that the failure (not surprisingly) primarily due to the fact that the engine still reaches the highest pressure in the camera. bit directly above the injector) was designed for nominal performance and reliably withstand extreme pressure of 250+ bar (3600+ psi), whose performance requires even higher pressures in the components that feed the hot methane gas and oxygen into the Raptor combustion chamber. One of the simple examples hinted at Muska in 2018 is the tweet is its oxygen preurner, used to convert liquid fuel into a high-speed gas that can then feed a dedicated turbine of oxygen. Except for the absurd corrosive environment created by extremely hot gaseous oxygen, the previous machine must also withstand pressure, which can reach a maximum of 800 + bar or 12,000 psi. Scope of the Raptor test with incredible speed. (SpaceX)

The lack of a technical detail means that it is difficult to know what pressure or the main camera pressure was in mind when referring to exotic alloys that would be needed to survive in these pressures, but the Raptor's work statistics with previous work at 800+ bar Maybe, perhaps, ahead of anything, as Mask still said, Of course, we can assume that the Raptor has probably not been advanced to these levels of performance, although this is still a remote possibility. It is more likely that an 800+ bar in an oxygen frontal chamber is an extraordinary goal that will achieve agreed research, development and optimization, as the Raptor has been damaged somewhere below these levels until it reaches performance.

For a complex engine like the Raptor, there are dozens of potential rejection modes that would come as a little surprise to the engine just days in a full-scale testing. First of all, the Raptor Test Schedule, conducted by the world-class SpaceX team, whether self-motivated or controlled by reckless controls using spreadsheets, quickly developed under extreme conditions, taking the first high-performance Raptor ever built from standing to over 90% of traction and The pressure in the chamber is almost 270 bar (3900 psi) in – literally – in less than a week. In the same period of time more than half a dozen static fire tests were performed (from 1-10 seconds).

Within a few days from the February 10th milestone, when the Raptor reached the pressure in the chamber, comparable to the most advanced Modern engines (namely, RD-180/190/191), the engine was probably sharply advanced even higher, reaching pressure in the chamber (and, therefore, traction), which damaged some of the more sensitive parts of the plumbing engine. Despite the fact that the second Raptor maker is probably "almost finished," Mus suggested that he already has changes (of unknown severity) to mitigate the bounce modes experienced by the Raptor SN01.

In a field where NASA and contractors such as Aerojet-Rocketdyne will spend months between static tests on space shuttle fire engines, each of which Literally flying some (if not) dozens of missions into orbit and demonstrating performance and reliability, which are measured in hundreds of thousands of seconds, speed and agility of the Raptor program and the SpaceX test program captures the spirit. It remains to see how end-to-end (ie Raptor) is relatively reliable and successful, but the position that actively accepts and even tests the destruction can ultimately serve only the end-product benefits from destroyed equipment and many lessons learned on the ground difficult by

Given the enormous success of the Merlin family of engines and the aggressive development and continuous improvement strategy that brought it from Merlin 1A to 1D and MVacD, SpaceX is clearly not bothered
