SpaceX starts with a static test of Starhopper, because the Raptor engine arrives in a schedule



SpaceX officially launched a static test of the Starhopper earth, a prototype prototype prototype that was supposed to support Raptor's early series of hop tests, at the launch of SpaceX in South Texas. At the same time, the second complete Raptor engine arrived on Monday, March 11th, confirming Ermon Musk's tweeters on March 8th for delivery.

While reasonably routine for any missile testing program, Starhopper's first launch test effectively marks the first time SpaceX has launched tests with more or less fully integrated Starship (previously BFS). Probably carried out with liquid nitrogen instead of liquid oxygen / methane, the first few testers will be used to determine the quality of stainless steel tanks – en Plain air in a rather unusual way – and to check if functional pressure vessels are without risking immediate and total destruction. If successful, SpaceX will continue to integrate with Raptor and integrate a static fire test before preparing for testers on floating tests, perhaps later this month.

In November 2016, SpaceX began testing fuel injection on its first complete hardware of Starship (then Big Falcon Spaceship), a mass liquid oxygen tank with a carbon made of 12 m (~ 40 ft) in diameter. In the course of 2017, SpaceX moved from liquid nitrogen to liquid oxygen and finally carried out one last burst test, in which the composite tank was pressurized until it exploded, finishing with complete BFR full-impact testing. Within 6-12 months, Musk came to the conclusion that BFR stainless steel would ultimately be a superior track for the rocket and space ship and tried (apparently successfully) to get its research and development engineers with such a radical change , and so late in the development phase.

Despite the fact that this radical departure of the design can take place only 6-8 months ago, SpaceX engineers and technicians have achieved an extremely fast development program that – in part – will culminate in the hope that the successful hop testing of Starhopper, the first star prototype . While more than a rough test of the real representation of hardware and structures that would be needed for the reuse of the starry orbital star class, Starhopper at least acted as a crash course (technical or organizational) in the construction and installation of aerospace structures in stainless steel, material which is largely a foreigner of the SpaceX flying space before the end of 2018.

Although the early vehicle was less than encouraging, as was the death of her nose as a result of improper planning and / or poor performance, Starhopper, as it stands now, can actually be easier in the context of subbibbing, pain-free hop tests. Powered by the same or similar raptures that will supply orbital prototypes, Starhopper's hop test will optimally provide a wealth of experience and engineering data for the construction of 9 m / 30 m diameter stainless steel rocket propellers and for engine / in actual flight configuration. Extensive testing with Raptor will help ensure that the equipment and finish of the new aircraft and hardware of the new engine are challenging for safe, reliable and gentle operations for a nominal vehicle for a launch and space launch.

60 hours later, the muscle was obviously not wrong.

About two days after Starchper was quickly flown from the construction site to a brand new SpaceX launch facility, the @spadre Twitter account (short for the island of South Padre) released a video of testing tanks that took place on March 11th, capturing the sound the ventilation as the liquid buffer turns into gas in the tank (s) of fuel. The fact that the person behind the camera was allowed to be where they were during the test, but guarantees that this first test was carried out with an inert liquid, probably liquefied nitrogen, given the massive delivery that occurred the previous day (March 10th) . In no impassioned world, SpaceX or local law enforcement will voluntarily allow Starhopper to be loaded – for the first time – with even a partial load of liquid methane or liquid oxygen with random passers who are a few hundred meters away.

SpaceX has accepted the delivery of several trucks of liquid nitrogen on March 10th, likely to support early tank penetration tests to confirm structural integrity and to check if it leaks. (NASASpaceflight – bocachicagal)

When SpaceX reaches the point that it is sufficiently confident in the structural integrity of Starhopper to begin practicing and testing wet dresses with real fuels, it is a sure bet that the company will cooperate with local law enforcement to block lonely access road to distance at least 1-2 miles, if not more. It is not clear whether local homeowners and residents will be forced to leave the Boca Chica village during the test, but chances are good that no one will be within a few thousand feet of Starhopper when fuel fill tests begin , s) are installed.

According to SpaceX's official progress report, fuel fatigue tests and static fires could begin "on the following days", although the spokesman was under the impression that these tests – like the initial hop tests -[would] not to be visible from the offsite. "Unless SpaceX plans to draw a retention zone with a radius of several miles, interested observers will almost certainly be able to get closer to at least take a look at Starhopper, but the statement still offers an idea of ​​how much it is focused company will be safe during these first tests.
