SpaceX’s new Starship test stand to make life a little easier for Raptor engine engineers

SpaceX recently debuted a new rocket engine test stand at its Central Texas advancement facilities and one element of the tripod stand’ will make life a lot simpler for Starship’s Raptor engine engineers.

The triumph of SpaceX’s tough Starship spacecraft and also Super Heavy boosters hinges greatly on the previous achievement of a rocket engine itself is being developed by that the company. Known as Raptor, the engine is probable among the most complicated ever produced, due to its usage of a combustion cycle which ’s unforgiving and as challenging as it’s efficient. This efficiency is your draw.

The decision to base the Starship launching system round methane and oxygen propellant – comparatively dense, secure to handle, and easy to create on Mars – ensures that it can never be as efficient as a rocket according to oxygen and hydrogen, the pinnacle of chemical combustion-based propulsion. For a methalox rocket as nominally reusable as Starship, moving to eke a smidge of extra efficiency out of its Raptor motors is a sensible – if not decision. But many barriers are carried by that pursuit of efficiency with it, some of which may even be exacerbated with the gear used to check those motors.

Raptor is unique in this case but SpaceX’s engine testing and development has grown to the point that the stands it’s relied on for fires have become a detriment to the engine’s advancement. Especially, besides Starhopper, all preceding Raptor static fires have been performed with motors installed horizontally in test bays situated at SpaceX’s McGregor, Texas growth facilities. While in flight, Raptor motors will never experience wear and tear similar to the distinctive requirements enforced by horizontal analyzing – engine burns will almost always exert forces along a vertical (up and down) axis.

To anyone else, even other engine growth companies, this may seem to be an insignificant difference. Constructed around the full-flow staged combustion (FFSC) cycle and meant to be unprecedentedly nontoxic and reliable, the Raptor engine isn’t quite as forgiving. Since the engine’s static flame test just 1 year ago, SpaceX CEO Elon Musk has noted several occasions that Raptor could gain from fresh vertical test racks.

Talking in October 2019, Musk stated that a new vertical test stand would “ideally enable simplification of Raptor design, as pump shaft wear & drainage is better in vertical config. ” More commonly, analyzing Raptor engines would likewise be agent of flight [states ]permitting SpaceX to live up to its proven “test as you fly” doctrine.

Aside from Starhopper’s test flights and a couple of fires that were static, Raptor has conducted any testing despite more than 3200 seconds of inactive fires performed with 18 full-scale engine prototypes in the last 12 months. Adding subscale engines analyzed in 2016 through 2018, SpaceX’s Raptor engine has probably completed some 5000 moments (>80 moments ) of test fires over the span of three and a half years of growth.

Besides enabling SpaceX engineers to possibly simplify the Raptor engine design and test the Starship motors in terms much closer to that which they will experience in flight, the addition of a new dedicated test stand – on top of 2 existing flat bays – should allow even more testing to be completed in a given time-frame. The more motors SpaceX can certainly qualify for flight, and also provided that every Starship/Super Heavy pair may require around 43 new Raptor motors, SpaceX will require the testing capacity it can get.
