Космический корабль "Орион" не выдержал испытания давлением

Конструкторы компании Lockheed Martin наконец-то сообщили, что тестирование капсулы "Орион", которое проходило в ноябре этого года, прошло не совсем успешно.
Космическая капсула "Орион", которая является многоцелевой и многоразовой пилотируемой капсулой, не выдержала испытания высоким давлением. Внутренняя часть корпуса треснула при давлении 149 килопаскалей в то время, как была рассчитана на 164 килопаскаля (приблизительно такое давление должна будет выдерживать капсула в космосе).

К сожалению, во время ноябрьских испытаний капсула "Орион" не выдержала и просто-напросто треснула. Инженеры, которые занимаются

постройкой и испытаниями капсулы "Орион" заявляют, что трещина будет быстро устранена, а корпус космического аппарата будет укреплен. Неудачные испытания не должны повлиять на запланированную дату первого испытательного полета этого космического аппарата.
    Напоминаем, что запуск многоцелевого космической капсулы "Орион" запланирован на 2014 год. Это должен быть первый испытательный полет американского частично многоразового аппарата.
    КА "Орион" заменит американские космические шаттлы, программа которых по доставке экипажей и грузов на МКС завершилась в 2011 году. Кроме этого, "Орион" будет использоваться для пилотируемых полетов к луне и Марсу.
    Несмотря на то, что ранее поступала информация о том, что в связи с недостатком финансирования, программа "Орион" временно приостановлена, космический корабль продолжает проходить тестирования и дорабатываться инженерами компании Lockheed Martin, которая строит эту капсулу по заказу американского космического агентства.

NASA Puts Orion Backup Parachutes to the Test
Space Travel, Huntsville AL (SPX) Dec 24, 2012

ЦитироватьNASA completed the latest in a series of parachute tests for its Orion spacecraft Thursday at the U.S. Army Yuma Proving Ground in southwestern Arizona, marking another step toward a first flight test in 2014.
The test verified Orion can land safely even if one of its two drogue parachutes does not open during descent.
Orion will take humans farther into space than ever before, but one of the most challenging things the multipurpose vehicle will do is bring its crew home safely. Because it will return from greater distances, Orion will reenter the Earth's atmosphere at speeds of more than 20,000 mph.
After re-entry, the parachutes are all that will lower the capsule carrying astronauts back to Earth.
"The mockup vehicle landed safely in the desert and everything went as planned," said Chris Johnson, a NASA project manager for Orion's parachute assembly system. "We designed the parachute system so nothing will go wrong, but plan and test as though something will so we can make sure Orion is the safest vehicle ever to take humans to space."
Orion uses five parachutes. Three are main parachutes measuring 116 feet wide and two are drogue parachutes measuring 23 feet wide.
The 21,000-pound capsule needs only two main parachutes and one drogue. The extra two provide a backup in case one of the primary parachutes fails.
To verify Orion could land safely with only one drogue parachute, engineers dropped a spacecraft mockup from a plane 25,000 feet above the Arizona desert and simulated a failure of one of the drogues.
About 30 seconds into the mockup's fall, the second drogue parachute opened and slowed the mockup down enough for the three main parachutes to take over the descent.
The next Orion parachute test is scheduled for February and will simulate a failure of one of the three main parachutes.
In 2014, an uncrewed Orion spacecraft will launch from Cape Canaveral Air Force Station in Florida on Exploration Flight Test-1. The spacecraft will travel 3,600 miles above Earth's surface.
This is 15 times farther than the International Space Station's orbit and farther than any spacecraft designed to carry humans has gone in more than 40 years. The main flight objective is to test Orion's heat shield performance at speeds generated during a return from deep space.

NASA, ESA Hold Jan. 16 NASA TV Briefing on New Orion Agreement

HOUSTON -- NASA and the European Space Agency (ESA) will hold a news briefing at 10:30 a.m. CST on Wednesday, Jan. 16, to discuss the details of a recent agreement for ESA to provide a service module for the Orion spacecraft's Exploration Mission-1 in 2017. NASA Television will carry the briefing live from the agency's Johnson Space Center in Houston.

The agreement, which expands on the successful partnership between the agencies on the International Space Station and other activities, ensures continued international collaboration as humans explore new frontiers in the solar system.

Orion will be the most advanced spacecraft ever designed and carry astronauts farther into space than ever before. The service module will be attached directly behind Orion and provide the capsule's power, thermal control and propulsion.

The news conference participants will include:
-- William Gerstenmaier, NASA associate administrator for Human Exploration and Operations
-- Thomas Reiter, ESA director of Human Spaceflight and Operations
-- Mark Geyer, Orion Program manager
-- Bernardo Patti, ESA manager of International Space Station operations

For those attending the briefing at Johnson, the deadline for U.S. reporters to request credentials is Monday, Jan. 14. The deadline for international residents is Tuesday, Jan. 8. Reporters wishing to attend at other NASA centers should contact those centers' newsrooms for specific deadlines.

To participate via the phone, reporters must contact the Johnson newsroom at 281-483-5111 no later than 10:15 a.m. the day of the briefing. Media will not be able to connect after the briefing has started.

Очень хотелось бы, чтобы получился в итоге аппарат-мутант с служебным модулем от ATV. Это последняя надежда использовать весьма богатое наследие короткой жизни последнего.

А Америка так и не сделала служебный модуль, все силы ушли на возвращаемый аппарат, так получается?

SFN · 07.01.2013 17:22:40

Для SM есть стапель и внутри несколько элементов каркаса (фото выше сообщ #2262)
В фейсбуке было помечено концом ноября, но судя по EXIFэтому фото уже больше года. (может дата в камере сбилась?)
(разобрался в чем прикол. загрузили на фейсбук их в конце ноября 2012))

И вообще это СМА - адаптер который все равно нужно делать для ЕвроSM

На НСФ woods170 говорит, что посылали запросы о работах по СМ. Результат: пшик
Other than that: the lack of information about work on the MPCV Service Module has been persistent for years now. Several members on this forum have requested about the state of affairs with regards to the SM multiple times over a period of years. Result: zilch.

ЦитироватьNASA To Review SLS Core Stage, Orion Weight Issues

An integrated systems definition review of NASA's three human exploration elements — launcher, capsule and ground systems — kicks off next week, with major items of discussion to include the schedule for developing the Space Launch System (SLS) core stage and the Orion crew capsule's weight.

The three-day review at Johnson Space Center will build on previous design work on the SLS, Orion and modifications at Kennedy Space Center, Fla., to make sure all of the requirements and interface control documents match up.

The SLS core stage is the "critical path" to the first flight test of an unmanned Orion multipurpose crew vehicle atop an early variant of the SLS in 2017, according to Dan Dumbacher, deputy associate administrator for exploration systems, and the Orion capsule weighs about 4,000 lb. more than its recovery parachutes can handle. Both issues are tractable, he says.

"Just before the holidays they completed the preliminary design review [PDR] on the core stage," he said Jan. 7. "Doing the review, we actually came through pretty clean, so we're gaining some confidence. Obviously, we have hardware in front of us [and] Mother Nature has a wonderful way of keeping us all humble."

'Acceptable risk'

The PDR determined the big rocket's main stage can meet requirements "within acceptable risk," and can be integrated with the surplus RS-25D space shuttle main engines that will power it for the first few flights. Combined with the solid-fuel, shuttle-derived boosters and other planned launch hardware, the initial SLS variant has enough extra capability to handle the overweight Orion capsule.

Specifications call for the Orion capsule and its service module to weigh 73,500 lb. at liftoff. Lately the capsule has been running "something like 4,000" lb. over its allotted weight, Dumbacher says. The service module is about 1,200 lb. too heavy.

While the baseline SLS probably can handle the extra weight, the parachutes that will bring the capsule back to a water landing after re-entry cannot, Dumbacher says. Going into the integrated review, design teams have been wringing out the extra weight on the capsule, he says, and an upcoming flight test atop a Delta IV heavy may allow engineers to cut their margins to save more weight.

Scheduled for September 2014, the flight test will take an Orion test article through a highly elliptical orbital trajectory designed to bring it back into the atmosphere at about 80% of the velocity it would see returning fr om the Moon or beyond.

"That is enough to start to tell us what we need to do fr om a heat-shield standpoint, and where we can reduce weight, or wh ere we might have to add weight, depending upon what we learn," Dumbacher says, adding that the flight test also will help designers decide whether they can take weight out of the capsule structure.

A press conference is scheduled during the Jan. 16 session of the integrated review to announce the formal agreement of the European Space Agency's (ESA) participation in developing the Orion service module, using propulsion-system hardware from ESA's Automated Transfer Vehicle.

"We're somewh ere between systems definition review level and PDR level on the maturity of that service module design from ESA," Dumbacher says. "There are still technical and programmatic issues and questions that have to be worked. We are not going to be able to lay out all the nuts and bolts and all the detailed designs, nor are we going to be able to lay out all the specific impacts to all the suppliers, down to the second, third and fourth tier. We still have work to do on it."
