Hello friends, welcome to Engineering Today, we are back with the latest updates for you and three updates on SpaceX for today. All fans of SpaceX, disappointed at the back-to-back delay of the Starship SN9, may be happy to learn that SpaceX has passed the first test of the new Starship ‘test tank’. Recently, high altitude flight testing of the SN9 starship was delayed due to lack of FAA approval for unknown reasons.
The launch has been delayed since early this week. Meanwhile, SpaceX found a way to conduct the first starship “test tank” stress test months later. SpaceX’s latest starship test tank, known as SN7.2, is the successor to its previous series (SN7.0 and SN7.1). Accordingly, Sn 7.2 is made of the same alloy used in previous test tanks. On Tuesday, a local photographer, Michael Beartovit, said, “SpaceX is testing today in Boca Chica with an SN7.2 3mm test tank. Teams will likely follow the same routine as previous SN7 test tanks, followed by testing K will be after several rounds of unsuccessful testing. ”The initial pressure test lasted approximately three hours, and SN 7.2 was defended. More likely, this test was inside the tank. According to Musk, 6 bar is the minimum value for orbital flight, but the value required to achieve an industry-level safety margin (25–40)% is about 7.5–8.5 bar.
The next day, Michael said, “The first cryogenic proof test appears to be successful, but there is no way to know for sure about the official wording.” Musk confirmed “passed the first pressure test” about two hours later on Twitter. Check the performance of the SN7.2’s thin skin, the tank can apply pressure to its limits until it bursts.
Stay tuned for special updates. Now, SpaceX’s super heavy booster. Based on the execution, we will proceed to the next part of our news. With the ongoing preparations and trials of the starship, SpaceX also focuses on building the Super Heavy Booster, which is the first phase of the starship. It has been reported so far that two prototypes of the Super Heavy Booster have gone through the stacking process.
SpaceX draws heavily on the experience gained in the construction, assembling, testing, and flight of previous starship prototypes and uses these experiences to build upgraded starships and super heavyweight prototypes. On January 25, 2021, a significant portion of SpaceX’s Super Heavy Booster prototype first appeared at the company’s South Texas starship factory, Boca Chica. SpaceX has the ability to use practically indistinguishable rigs, jigs, gears, and modes of operation to build and assemble fuel tank barrels and domes for both the Starship and Super Heavy.
SpaceX’s teams will create a broad base for the two-stage starship, which includes avionics, propulsion, ground systems, and plumbing. With its twenty-eight Raptor engines and improved thrust, Super Heavy will be the world’s largest, highly developed, and most powerful liquid-fuel rocket booster when completed. SpaceX summon would start using the explosive methods they used to prototype the starship.
The SpaceX teams at the Boca Chica facility ran a series of hydraulic piston-spooling units to build a larger and more powerful test stand to carry the Super Heavy Booster Thrustof 28 Raptor engine. More recently, a steel structure recently spotted an airship on a flight to SpaceX’s Starship factory. RGVAerialPhotography tweeted on January 25, “Could this new stand be for SH?” .It is expected that the first booster will be fully assembled and ready for testing in a short period of time.
The Starship’s second stage uses a small central “thrust disc” for three Raptor engines adapted to sea level and has future intentions for three large vacuum-optimized engines to be fixed at the edge of its hull. SpaceX CEO Elon Musk previously stated that Super Heavy will have a central cluster of eight engines, but specific models have not yet been revealed. There are eight gimbolating raptor engines with eight oversized steel rings in the photographs taken by Jack Baird, Mary of BocaChaigal, and more recently NASASpaceFacelight.
The remaining twenty Raptors are a chance to place the engine on a skirt or thrust dome; They can also be installed in the gap between the pressure wheel and the super heavy skirt. Jack Baer from NASASpaceflight, b on January 25.Photo of BN1’s tank dome, “Oh hey, the backward dome of Super Heavy Booster No. 1. Looks like a spot for four raptors? Great.” Compared to starships is less complicated because they do not configure motors will only have grille wings to re-enter the atmosphere.
The super-heavy booster will produce at least 6600 metric tons of thrust in the lift, which is about three times the thrust force of the Falcon Heavy. Therefore, the annular steel structure and the hole behind the two rings of the raptor motors should be able to sense such thrust. The steel structure would have to exert 1600 tons of thrust with one hand, while gravity, acceleration, and thrust of about 2500 tons of suboptimal liquid oxygen in the opposite direction. Creating super heavy was an exceptionally difficult task for SpaceX. SpaceX has already started building the first real prototype with the aim of rebuilding more models in the future. SpaceX hopes to focus on Super Heavy’s first test campaign in addition to emphasizing the rocket’s thrust structure design when the number one prototype booster (BN1) successfully passes basic pressure and cryogenic evidence. Let’s go to the last part for today.
SpaceX took the next step of its Star Link broadband program by launching Ten Star Link in polar orbit equipped with Laser Star Link. Recently, SpaceX launched its record-breaking Transporter-1, where SpaceX launched a total of 143 satellites, including its own Starlink satellite.
It was under the star-linked constellation program. Now, SpaceX launches several Starlink satellites once a month, but the launch on the Transporter-1 mission was different from other Starlink launches. In this mission, SpaceX launched its first stellar link satellites in polar orbit equipped with laser crossovers. Following the launch of the Transporter-1 mission, Elon Musk, CEO of SpaceX, stated in a tweet that these Starlink satellites were equipped with inter-laser satellite links. “These satellites also have laser connections between their satellites, so there is no need for ground stations at the poles,” Musai said.
Now, intersatriary laser crosslinks) is a technology that provides better communication routes with increased data throughput. This type of technology takes advantage of shorter wavelengths and lower beam deflection and sends highly directed signals over relatively long distances. SpaceX plans to use the technology on other Starlink satellites next year. Musk personally shared the news that a StarLink satellite equipped with laser cross-link technology will be on the market next year. “All the satellites launched next year will have laser connections.
Only our polar satellites have lasers and we have v0.9,” Musk said in a tweet. To maximize internet connectivity in Alaska and minimize the need for ground stations, the StarLink laser link allows ground stations in remote areas to share communications without assistance, according to SpaceX, by launching a laser crosslinked Starlink satellite on the Polar Orbit SpaceX targets Please allow. As a result, it will significantly extend the usability range of Starlink Internet connections in many narrow areas.
Furthermore, it will provide links with minimal delay as the number of hops between satellites and ground stations decreases. According to the information received, SpaceX has been testing inter-satellite connections on other Starlink satellites for some time. As Musk said in a previous tweet, these satellites will be launched next year. SpaceX also said that they were testing “spacers” between the two satellites by transferring hundreds of gigabytes of data. “Once these space lasers are fully deployed, Starlink will be one of the fastest options available for data transfer worldwide,” SpaceX said in a webcast.
