《星艦飛行 3》地平線上的濕裝排練

SpaceX is deep into preparations for the next Starship flight, focusing on the Orbital Launch Pad (OLP). Booster 10 and Ship 28 are set to return to the launch site in the coming week or two, ahead of a Wet Dress Rehearsal (WDR) that will set the stage for the third launch of the world’s largest and most powerful rocket.

SpaceX 正在深入準備下一次星際飛船飛行,重點是軌道發射台(OLP)。助推器 10 號和船 28 號將在未來一兩週內返回發射場,隨後進行濕裝彩排 (WDR),這將為世界上最大、最強大的火箭的第三次發射奠定基礎。

Upcoming Wet Dress Rehearsal

即將舉行的濕衣彩排

With both Ship 28 and Booster 10 expected to return to the pad next week at the earliest, SpaceX would be able to hold to their timeline of having vehicle readiness by the end of January.

由於 Ship 28 和 Booster 10 預計最快將於下週返回發射台,SpaceX 將能夠堅持在 1 月底之前完成車輛準備就緒的時間表。

Recently, Ship 28 was taken off the turntable and placed on a transport stand. Once both vehicles return to the pad, the expectation is SpaceX will complete a WDR just like the last two flights.

最近,28號船被從轉盤上取下並放置在運輸台上。一旦兩輛車返回發射台,SpaceX 將像前兩次飛行一樣完成 WDR。

This WDR could be even more vital than the last two completed because of the upgrades and changes to the Orbital Tarm Farm (OTF). Since Flight 2, SpaceX has installed extra pumps and subcoolers as well as changed up the plumping so that the ship subcoolers are separate from the booster ones. This would help improve efficiency in getting the stack fueled much quicker.

由於軌道塔姆農場 (OTF) 的升級和更改,此 WDR 可能比前兩次完成的更為重要。自第二次飛行以來,SpaceX 安裝了額外的泵浦和過冷器,並改變了管道系統,以便船舶過冷器與助推器過冷器分開。這將有助於提高效率,並更快地為電池組提供燃料。

Changes to the Orbital Tank Farm and Launch Site

軌道罐區和發射場的變化

After the rollback of Booster 10 and Ship 28, SpaceX began to remove and scrap the old water tank and one of the repurposed Methane tanks. The old water tank hadn’t been in use for some time because leaks started appearing early on, and SpaceX had to abandon it.

在 Booster 10 和 Ship 28 回滾後,SpaceX 開始拆除並報廢舊水箱和一個重新利用的甲烷罐。舊水箱已經有一段時間沒有使用了,因為很早就開始出現洩漏,SpaceX 不得不放棄它。

That water tank was just a cryo shell like the others used on the other cryo tanks. However, no additional reinforcement was added to it, which is why the tank was abandoned. The repurposed methane tanks filled the role of this water tank, which is used for heat exchangers located in the cryo bunker. These heat exchangers are likely used to help heat up Liquid Nitrogen, which is then used to help purge and add pressure to the cryo lines.

那個水箱只是一個低溫外殼,就像其他低溫箱上使用的其他外殼一樣。然而,由於沒有對其進行額外的加固,這就是該坦克被廢棄的原因。改造後的甲烷罐填補了該水箱的角色,該水箱用於位於低溫掩體中的熱交換器。這些熱交換器可能用於幫助加熱液態氮,然後用於幫助淨化和增加低溫管線的壓力。

SpaceX is also adding large vertical I beams and cross supports to the Liquid Nitrogen Tank and the still remaining Water tank that is exposed to the exhaust plume. These are to reinforce the cryo shell during static fires and launches because the cryo shells that have now been removed were damaged due to sound waves from engine firings.

SpaceX 還為液態氮罐和暴露在廢氣羽流中的剩餘水箱添加了大型垂直工字樑和十字支撐。這些是為了在靜態發射和發射期間加固低溫外殼,因為現在已被拆除的低溫外殼由於引擎點火的聲波而損壞。

Over the past several weeks, SpaceX has been completing small upgrades all over the OLP. The HESCO barriers that were next to the main blast wall protecting the tank farm were removed and are being replaced by a concrete wall. Plates are being added on top of the concrete at the base of the tower because of erosion from all the engine firings.

在過去的幾周里,SpaceX 一直在整個 OLP 上完成小型升級。保護罐區的主防爆牆旁的 HESCO 屏障已被拆除,並被混凝土牆取代。由於所有引擎點火的侵蝕,在塔底部的混凝土頂部添加了板材。

The Ship Quick disconnect arm was repainted, and SpaceX could be doing upgrades to the arm as well. Several burn plates on the Orbital Launch Mount (OLM) ring have been replaced, especially the ones near the Booster Quick Disconnect. Those get more cooked than others because of the pad avoidance maneuver that Starship performs at liftoff. 

Ship Quick 斷開臂重新噴漆,SpaceX 也可能對該臂進行升級。軌道發射架(OLM)環上的幾個燃燒板已被更換,尤其是助推器快速斷開附近的燃燒板。由於星際飛船在升空時執行的避免墊動作,這些飛機比其他飛機更容易煮熟。

These plates act as an ablative armor for the OLM deck and inner ring. Along with all the small upgrades, SpaceX is taking this time to repair damage still left over from Flight 1, such as repairing welds inside the OLM. SpaceX still has a lot of work to do to make this pad easily refurbished.

這些板充當 OLM 甲板和內環的燒蝕裝甲。除了所有的小升級之外,SpaceX 還利用這段時間修復 1 號航班遺留的損壞,例如修復 OLM 內部的焊接。為了讓這個發射台能夠輕鬆翻新,SpaceX 還有很多工作要做。

Along with all the changes to the OTF, the SpaceX LR11000 crane was laid down, and SpaceX and Buckner have been taking the crane apart piece by piece. It is unclear if this is heavy maintenance considering this was first raised over two years ago, or if it is being taken apart to be shipped to another location.

隨著 OTF 的所有變化,SpaceX LR11000 起重機也已安放,SpaceX 和巴克納一直在將起重機一塊一塊拆開。考慮到這是兩年多前首次提出的,目前還不清楚這是否是一項繁重的維護工作,或者是否正在被拆開運送到另一個地點。

Tower Two and Sanchez

二號塔和桑切斯

SpaceX has started putting together some of the pieces for tower two at Sanchez, and one of the pieces for the top section that holds the pulleys for the draw works arrived this week. SpaceX has built up an entire area at Sanchez dedicated to building the second tower and pad and is expected to ship most of the materials from the Cape.

SpaceX 已開始組裝桑切斯二號塔的一些部件,用於固定牽引裝置滑輪的頂部部件之一已於本週抵達。 SpaceX 在桑切斯建立了整個區域,專門用於建造第二座塔和發射場,預計將從開普敦運送大部分材料。

It is still unclear where this second tower will be located. However, in a recent all-hands meeting, SpaceX CEO Elon Musk showed an older animation where the second tower was to the south. But, there has yet to be a confirmation if that was still the case. Starbase General Manager Kathryn Lueders mentioned that this would be a launch tower several weeks back.

目前尚不清楚第二座塔將位於何處。然而,在最近的一次全體會議上,SpaceX 執行長馬斯克展示了一個較舊的動畫,其中第二座塔位於南邊。但是,情況是否仍然如此還有待確認。 Starbase 總經理 Kathryn Lueders 幾週前提到,這將是一座發射塔。

SpaceX is still working on the second Booster transport stand as well as the second Ship work stand for the Ship Bay. Once those are complete, work should start on the third transport stand and work stand. 

SpaceX 仍在建造第二個 Booster 運輸站以及船艙的第二個船舶工作台。一旦這些完成,就應該開始第三個運輸站和工作站的工作。

Ship 26 has been on the engine install stand since Jan 10, and SpaceX is still adding more stringers to the payload section. What Ship 26 will be used for in the future is still a mystery, but the most likely outcome is a structural test article.

自 1 月 10 日以來,26 號船一直在引擎安裝台上,SpaceX 仍在為有效載荷部分添加更多縱梁。 26號船未來的用途仍然是個謎,但最有可能的結果是結構測試品。

Production Site

生產現場

SpaceX has been making great progress on Starfactory and getting the New High Bay (Ship Bay) fully kitted out and built. The roof on the new Ship Bay’s roof is nearly complete, and SpaceX has been installing all of the lights and elevator equipment inside. Starfactory has been constantly growing, and footings are already starting to be dug out where Tent 3 was, which will be the final section of the factory.

SpaceX 在 Starfactory 上取得了巨大進展,並完成了新高灣(船灣)的全面裝備和建造。新船艙的屋頂已接近完工,SpaceX 已經在裡面安裝了所有的燈光和電梯設備。 Starfactory一直在不斷發展,3號帳篷所在的地方已經開始挖地基,這將是工廠的最後一個部分。

The Ringyard is completely cleaned out as SpaceX is starting the final section of Starfactory. A Booster common section, a Nosecone section, and a booster forward section were moved behind the High Bay, and everything else was pushed to the new scrap yard in Sanchez. 

隨著 SpaceX 開始啟動 Starfactory 的最後部分,Ringyard 已完全清理乾淨。助推器公共部分、鼻錐部分和助推器前部部分被移至高灣後面,其他所有東西都被推到桑切斯的新廢料場。

Masseys

梅西大學

After the cryo testing of Ship 30 and Booster 12, SpaceX continued the construction of a possible flame trench and static fire stand for ships. Currently, SpaceX is still using Suborbital Pad B for static fire testing, and it is unknown if SpaceX has the approval for static fire vehicles at Masseys, like at the launch site. But paperwork could be in the works for such testing.

在對 Ship 30 和 Booster 12 進行低溫測試後,SpaceX 繼續為船舶建造可能的火焰溝和靜態消防站。目前,SpaceX 仍在使用 Suborbital Pad B 進行靜態消防測試,目前尚不清楚 SpaceX 是否獲得了梅西大學靜態消防車的批准,就像在發射場一樣。但此類測試的文書工作可能正在進行中。

Along with the construction of the possible flame trench, SpaceX has installed cryogenic pumps, subcoolers, and extra tanks to support a static fire stand.

在建造可能的火焰溝的同時,SpaceX 還安裝了低溫泵、過冷器和額外的水箱來支援靜態消防站。

Vehicle Updates

車輛更新

Flight 4’s vehicles, Ship 29 and Booster 11, are still on their respective work stands getting kitted out for static fires and flights. Flight 5’s vehicles, Ship 30 and Booster 12, have both completed cryo, and Booster 12 is not on a work stand after having rolled back recently.

Flight 4 的車輛、Ship 29 和 Booster 11 仍在各自的工作台上,準備靜態火力和飛行裝備。 Flight 5 的載具 Ship 30 和 Booster 12 都已完成低溫處理,而 Booster 12 近期回溯後並未出現在工作台上。

Ship 30 is still waiting for the next stand to be installed in the Ship Bay. With Booster 12 being placed on the center work stand there is now three full boosters inside Mega Bay getting engines or being worked on.

30 號船仍在等待在船灣安裝下一個支架。隨著 Booster 12 被放置在中央工作台上,Mega Bay 內現在有 3 個完整的助推器正在安裝引擎或正在維修。

Along with three full boosters in the Mega Bay a big milestone was hit for Flight 6 as Booster 13’s Methane tank is finished stacking. This makes nearly four flight capable boosters complete at once.

隨著 13 號助推器的甲烷罐完成堆疊,與 Mega Bay 中的三個完整助推器一起,6 號航班也達到了一個重要的里程碑。這使得近四個具有飛行能力的助推器同時完成。

Currently, other than catching glimpses of possible Version 2 parts inside Starfactory, there is little evidence that anything will appear outside of the factory anytime soon. The first pieces of Version 2 could just be pathfinder test tanks.

目前,除了在 Starfactory 內瞥見可能的第 2 版零件外,幾乎沒有證據表明任何東西很快就會出現在工廠外。第 2 版的第一批產品可能只是探路者測試坦克車。

Hopefully, there is evidence of the second tower being started soon, along with pieces of Version 2 of Starship showing up.

希望有證據顯示第二座塔即將啟動,同時出現第二版星際飛船的碎片。
