Тогда горловины выше обычного двигателя. "Выдвинутые", "с большим соплом" находятся рядом, ближе к краям.

Это самое существенное противоречие для данной теории.
Однако, есть еще один вариант: Размещение трубопроводов (и другого оборудования) системы перекачки топлива из боковых блоков FH.

Мысль дальше движется в сторону боковых блоков с зеркальной компоновкой)

Ну да.

а что не полетели? вроде 15-го собирались

[testest]

Во время прожига обнаружились какие-то "аномалии". Нужен еще один прожиг для проверки, а потом на Ванденберге начинаются военные пуски. Короче, теперь только 29-30-го.

Видно что Маск ничего не хотеть рисковать, при подготовке были маленкие несправности или аномалии. Делает всё чтобы полет был удачный. Он сам ранее сказал, что от многоразовых носители зависит его судьба.

[LRV_75]

Ну, тут спешить, делу грешить, ok, подождем

Скорей просто решили не совмещать с Антаресом

December ISS Mission Delayed By Dragon Upgrades

Space Exploration Technologies (SpaceX) is modifying its Dragon capsule to afford more payload capacity for NASA cargo runs to and from the International Space Station (ISS). But the improvements will push a planned December ISS mission into 2014, in which the company's crowded launch manifest is pending the delayed debut of the revamped SpaceX Falcon 9 rocket.

President Gwynne Shotwell says NASA needs SpaceX to make the Dragon enhancements in order to increase the reusable cargo vessel's cold-storage capacity for transporting research samples between Earth and the ISS.

"We're developing a major upgrade to Dragon to triple the amount of science that we carry up and back," Shotwell said Sept. 10 at the World Satellite Business Week conference here, adding that the capsule's December mission is now scheduled for February.

Under the terms of SpaceX's $1.6 billion Commercial Resupply Services (CRS) contract with NASA, the company is supposed to deliver 20,000 kg (44,000 lb.) of food, supplies and science materials to the ISS by Dec. 31, 2015. Dragon's advertised payload capacity is for more than 3,300 kg of pressurized and unpressurized cargo to the space station and up to 2,500 kg on the return trip.

Since the December 2008 CRS contract was signed, however, Dragon has conducted just three trips to the ISS, delivering a combined 1,595 kg of pressurized cargo and returning a total of 2,120 kg to Earth.

NASA spokesman Joshua Byerly says no new requirements have been added to the SpaceX CRS contract, suggesting the upgrades are expected to fulfill a long-standing requirement to meet ISS cargo needs. But he says the work is taking longer than initially planned.

"The December launch date was chosen in cooperation with SpaceX and assumed the enhancements being implemented by SpaceX," Byerly explains. "It is simply taking longer to get all the modifications completed, which is not unreasonable, given the nature of the enhancements."

In the meantime, SpaceX is still sorting out technical troubles with a new version of its Falcon 9 rocket.

More than a year behind schedule, the Falcon 9 v1.1 is a significant departure from the baseline Falcon 9 that has launched four times since its first flight in December 2010. The changes include a complete redesign of the vehicle's Merlin 1 engine, known as the Merlin 1D, and a new octagonal configuration for the rocket's nine first-stage motors. Other enhancements include considerably longer fuel tanks and a wider payload fairing. All the upgrades are aimed at lofting more mass—including crew—to the ISS, while affording entry to the commercial launch market. Falcon 9 has more than $1 billion in commercial-launch backlog to execute in the coming years.

Previously slated to debut Sept. 15 from SpaceX's new launch pad at Vandenberg AFB, Calif., the company shifted the Falcon 9 v1.1 mission to the end of September following a recent static-fire test. SpaceX founder, CEO and Chief Technology Officer Elon Musk stated on Twitter Sept. 13 that during the 2-sec. test, the rocket's nine engines achieved full thrust, but that "some anomalies" need to be investigated. Two days later, he tweeted plans to conduct a second static-fire test before launching Sept. 29-30.

For its first flight, the new Falcon 9 is expected to deliver a small Canadian science satellite to an elliptical polar orbit. If successful, this will clear the way for SpaceX to conduct its first commercial mission to geostationary transfer orbit, launching the SES-8 satellite for SES, the world's second-largest satellite fleet operator by revenue. SES-8 was expected to launch from Cape Canaveral in the first quarter of this year. SES says it is waiting to deliver the Orbital Sciences Corp.-built spacecraft to Vandenberg until the first Falcon 9 v1.1 mission is successfully lofted.

In addition to SES-8, Shotwell says SpaceX is planning to put the Orbital-built Thaicom 6 communications satellite into orbit by year-end before launching at "a cadence of almost one a month in 2014." For now, the company is producing four Merlin 1D engines per week, but plans to increase the rate to five per week starting in January, she says. This pace is necessary to keep up with SpaceX's busy launch manifest, which indicates 12 Falcon 9 v1.1 missions next year, including the one to the ISS in February.

"Our production is now ahead of our launch," Shotwell adds. "We have to get these vehicles to the launch site and fly them, but production should not be an issue going forward."

SpaceX is ramping up production on Falcon 9 rockets and Dragon spacecraft.

Production at SpaceX
As the only operational vehicle capable of taking significant amounts of cargo both to and from the International Space Station, SpaceX's Dragon spacecraft is already a critical piece of the American space program. With at least 10 more station resupply missions over the next couple years, and with development of a human-rated Dragon and DragonLab underway, production of the Dragon spacecraft has increased significantly.

No other American company is mass producing spacecraft at the same rate. Pictured below are no less than six Dragons in production, as SpaceX ramps up to keep pace with its plans and a very full manifest:

Top row (left to right): Commercial Resupply Services (CRS) 6 Dragon, pad abort Dragon weldment for commercial crew, CRS-5 Dragon. Bottom row (left to right) CRS-4 Dragon, drop test Dragon for commercial crew, CRS-3 Dragon (inside our clean room).

In addition to being a hub of Dragon activity, SpaceX has also increased production on its upgraded Falcon 9 vehicle. More than 70% of each Falcon launch vehicle is manufactured or assembled at the SpaceX Hawthorne production facility, which allows SpaceX to avoid the pitfalls associated with single-source parts dependency and gives the company competitive advantages in quality, cost and schedule control.

Ease of manufacturing is inherent in the Falcon 9 design. Each Falcon 9 is identical, regardless of the type of mission it will fly—from low Earth orbit to geosynchronous transfer orbit to resupply of the International Space Station. Commonalities in the vehicle's subassemblies also facilitate rapid production. For instance, the second-stage tanks of the Falcon 9 are a shorter version of the first-stage tanks and use most of the same tooling, material and manufacturing techniques. The second-stage engine is a modified, vacuum version of the engine used to power the first stage. The fuel tanks feature a common bulkhead design for the liquid oxygen and rocket-grade kerosene. Falcon 9's propellant tank walls and domes are both made from an aluminum-lithium alloy.


To accommodate a high production rate, the facility's manufacturing footprint has more than doubled to almost 1 million sq ft. SpaceX produces more rocket engines than any other U.S. manufacturer and the SpaceX factory is one of the largest manufacturing facilities in California—large enough to fit two complete Falcon 9's end to end along the short length of the building. With a floor plan designed around mass production, the factory is already se t up to eventually achieve a pace of forty cores annually.

Ну и завал у них там, как на "Дугласе" в 70-е. А почему секции обечайки вертикально? Вроде не было раньше такого, варили лежа. Зачем, ведь теперь надо поворачивать после сварки, стало быть все равно нужны распорки? Смысл?

Ну вобщето Спейс Икс сейчас это примерно то же что Дуглас в 70-е, точнее в 60-е. Частная фирма только взявшаяся за изготовление космической техники. 

Тут гдето была фотография сборочной линии вторых ступеней Дельты-2. Блин, там такой сарай-подвал...

[Старый]

Что касается обечаек то они без привареного силового набора могут и прогнуться под собственным весом. Приходится держать стоя.

Варят горизонтально, а хранят без подкрепления вертикально. В крайнем правом ряду стоит сварочный домик. Там у спейсексов, похоже, сварочный участок.
