Super Heavy Booster, SpaceX rolls upgraded Super Heavy booster to the launch pad

Super Heavy Booster, SpaceX rolls upgraded Super Heavy booster to the launch pad,SpaceX Rolls Upgraded Super Heavy Booster to Launch Pad SpaceX has begun transporting an upgraded Super Heavy booster to its South Texas launch facilities, where rockets will be tested with a rarely used stand , known as Crusher on Wednesday 30 March.

SpaceX signs a temporary road closure of transportation operations on March 31 The Super Heavy Booster 7B7 High Bay was assembled several times before Friday only to be rolled back inside at the end of the day SpaceX continued to work Decided to keep the booster inside High Bay’s shelter, while a separate team focused on preparing the Starbase Orbital Launch Site hole.

The 4b7s arrival together with the Moving Booster 7 made room for SpaceX to begin stacking Booster 8, which is centered around work on the pad on the same day. One thing in particular is a giant mechanical device affectionately known as a can crusher, made up of two large steel structures that were somewhat primary for attempting to crush the Str Starship test tank and the super heavy prototype SpaceX Purpose is.

The lower half of the Structural Test Stand is taken to the orbital launch site a few days before Booster 7’s first brief visit. A later tweet above unofficial aerial photography of Starbase showed SpaceX having modified the stand with 13 hydraulic rams, but guaranteed it would be used to test SpaceX’s next Super Heavy B7.

It is the first booster designed to use the upgraded Raptor V2 engine and 33. No less of them, Boosters 3 and 4, had room for 29 older Raptors that required a redesigned thrust section to increase the number of engines to 14, increasing the number of central gimbaling Raptors from 9 to 13. Does.

 

The Raptor v2’s upgrades are far more consequential, although simplifications on top of the major design that should reduce the cost of manufacturing the Raptor v2’s maximum thrust were increased from about 185 tons to 230 tons by 410 000. Combined with 10 000 lbf more engines the Super Heavy Booster 7 could theoretically produce approximately 7 600 tonnes (16.7 mlbf) of thrust at liftoff.

While Booster 4 which never fired one of its 29 Raptor V1.5 engines, it could produce approximately 5 400 tons (11.9 mlbf) due to an increase in 40 max thrust requiring an equally strong thrust section. which involves a large number of invisible design changes, those changes now need to be qualified.

And it appears SpaceX may be using an entire Super Heavy Booster b7 that could one day fly to verify their performance. The first part of testing a cheaper more disposable test tank would involve simulating a thrust of at least 13 of the Booster 7’s engine, the test stand cap can also be installed on top of the Booster 7.

 

When it arrives on the pad to potentially allow SpaceX to simulate both the thrust of all 33 engines and the stresses caused by acceleration during launch reentry and landing, SpaceX has begun installing a custom fixture and plumbing that will support its Will allow all structural testing to happen while the super heavy liquid nitrogen is filled with LN2 or oxygen lock.

Adds another layer of stress assuming that the structural test stand is strong enough to support SpaceX’s several thousand-ton boosters. With gentle ln2 or full cryogenic proof testing with locks and even wet dress rehearsals with flammable locks and the same setup the methane propellant fully proof Booster 7 can be fitted with the Raptor 2 engine.

Can be installed on the Starbase Orbital Launch Mount for road-based stationary fire testing. Closer SpaceX wants at least the option to begin testing Booster 7 on Friday, April 1, a day after its arrival at the launch site, if test preparation slips to the right that would lead to additional opportunities on April 4 and 5.
