Значит, auxiliary парашюты появились позже 2007 года? (На картинке их нет)

Как планировалось раньше не смотрел, пока както так:
1)2 мортирки стреляет парой FBC-парашютов, они уводят Forward Bay Cover (крышку переднего отсека)
2)2 мортиры стреляют парой Drogue Chutes тормозных парашютов.
3)3 Pilot Chutes + attached D-Bags вытяжные п. срывают с основных п. клапан и вытягивают их.
4)3 Main Chutes основные п. выводятся зарифленые и после наполнения раскрываются полностью.

[V.B.]

Что-то в этом списке нет auxiliary (может это запасные?)

Площади получились такие:
- тормозной (drogue) 38,6 кв.м
- вытяжной (pilot) 7,0 кв.м
- основной (main) 1097 кв.м

Основной примерно союзовского размера, но их три. Наверное командный отсек втрое тяжелее СА "Союза", да?

RELEASE : 12-065
NASA Continues Orion Parachute Testing for Orbital Test Flight[/size]
 
HOUSTON -- On Feb. 29, NASA successfully conducted another drop test of the Orion crew vehicle's entry, descent and landing parachutes high above the Arizona desert in preparation for the vehicle's orbital flight test in 2014. Orion will carry astronauts deeper into space than ever before, provide emergency abort capability, sustain the crew during space travel and ensure a safe re-entry and landing.

An Air Force C-17 plane dropped a test version of Orion from an altitude of 25,000 feet above the U.S. Army's Yuma Proving Grounds in Arizona. Orion's drogue chutes were deployed between 15,000 and 20,000 feet, followed by the pilot parachutes, which deployed the main landing parachutes. Orion landed on the desert floor at a speed of almost 17 mph, well below the maximum designed touchdown speed of the spacecraft.

The test examined how Orion's wake, the disturbance of the air flow behind the vehicle, would affect the performance of the parachute system. Parachutes perform optimally in smooth air that allows proper lift. A wake of choppy air can reduce parachute inflation. The test was the first to create a wake mimicking the full-size Orion vehicle and complete system.

Since 2007, the Orion program has conducted a vigorous parachute air and ground test program and provided the chutes for NASA's successful pad abort test in 2010. All of the tests build an understanding of the chutes' technical performance for eventual human-rated certification.

В НАСА протестировали парашютную систему космического корабля "Орион"[/size]
02.03.2012   07:29 http://www.vesti.ru/doc.html?id=731099

В НАСА успешно провели испытания космического корабля "Орион". Тестировали парашютную систему. Посадочную капсулу спускали с военного самолета на высоте семь с половиной километров. Парашюты раскрылись, и модуль успешно приземлился на военном полигоне в штате Аризона.

Первый полет "Ориона" запланирован на 2014 год. В 2010 возникли проблемы с финансированием проекта. Его даже предлагали закрыть. Президент США Барак Обама эту идею не приветствовал и распорядился сократить расходы на аппарат.

Вельми интересно и вызыввет вопрос: сколько создавали Аполлон и сколько уже ваяют Орин?
Учитывая что средства проектирования с тех пор как бэ сильно продвинулись

Опять же есть ощущение, что шестерым в Орионе будет гораздо теснее, чем тем троим в Аполлоне....

Шестиместный Орион - спасательная капсула для МКС, обычный полётный - четырёхместный.
Для любителей консервов существует 10-местный в том же объёме.
Спасибо Petrovich-у за наглядную агитацию.

Ну и как четырем в Орионе к Луне будет по сравнению с троими в Аполлоне к Луне?

Tile Makers Creating Orion Shield

Workers recently began cutting and coating the first thermal protection system tiles – part of the heat shield that will protect an Orion spacecraft during an upcoming flight test which will simulate the re-entry speed and heating of returning from deep space.

The tiles are made of the same material and coating as those used on the space shuttle's belly. On Orion, however, the tiles will be placed along the sides and top of the conical spacecraft. A separate heat shield akin to the ablative design used during Apollo is being developed to protect the bottom of the spacecraft, which will encounter the highest temperatures.



The manufacturing work at NASA's Kennedy Space Center, Fla., marks an important time in the progression of the spacecraft following the shuttle's retirement in 2011, said Thermal Protection System, or TPS, engineers Joy Huff and Sarah Cox.

"We're making something that's going to fly again, which is what we were doing for years," Huff said.

There are about 40 people involved in the tile work: 20 to make the tiles and 20 to install them.

"We're at the starting line," Cox said. "It's going to take some time to get all the parts fabricated."

The same shop that manufactured space shuttle tiles will make the 1,300 tiles needed for the Orion flight.

It is not fast work. In fact, workers will spend about 11 months shaping the insulating blocks and laying on a heat-resistant, ceramic coating. They use a 5-axis mill loaded with precise dimensions to cut blank tiles to their shapes. So far, the shop has finished 33 tiles.

Many of the tiles will have special cutouts for instruments to collect data during the flight test. Many fewer cutouts will be needed for future missions.

In an advancement from the shuttle days, each tile's dimensions are sent over digitally from Orion builder Lockheed Martin and the final tile is photographed with a 3-D camera so computers can fit the pieces together virtually before they are placed together physically, Huff said. The details are far more exact than in the past.

"They've had such good success that (technicians) are going to eliminate one pre-fit step," Huff said.



The comparisons with the tile work for the space shuttles are plentiful. For example, the smaller Orion uses tiles that average 8-inches by 8-inches compared to the shuttle's 6-inches by 6-inches. Also, Orion's design allows for many of the tiles to be the same dimensions with the same part number, but each shuttle tile was a unique configuration unto itself, with individual part numbers.

"That's a huge improvement over shuttle," Huff said. "Even having nine or 10 of the same part is a big improvement."

Perhaps the biggest comparison, though, is the sheer number of tiles involved. A space shuttle heat shield required more than 23,000 tiles to the Orion's 1,300.

"It's smaller, so there's less parts," Cox said.

However, Orion's tiles will be used only once because the spacecraft will splashdown in the ocean, drenching the absorbent tiles. That means that technicians will make and install all 1,300 tiles between Orion missions. Shuttles required 100 to 150 new tiles between flights, Cox said.

Technicians who applied the tiles for the shuttle will bond Orion's tiles, too. That work will start sometime in the summer. The tiles will be connected to nine panels that will be connected to the spacecraft to make the outer skin of the spacecraft.

Although it's a new spacecraft with a new mission, it still calls for many of the same skills the work force at Kennedy used for 30 years of shuttle preparation.

Orion is expected to see significantly hotter re-entry temperatures because it will be slowing down from about 25,000 mph when returning from the moon or some other deep space destination. Space shuttles used their heat shields to slow down from about 17,000 mph, the speed required to stay in orbit around Earth.

"The heat shield has been a very technological challenge and it will continue to be," said Huff, who has been working Orion's TPS development since 2005.

To get to this point, when tiles are being cut that will be used on a mission in space, has given the project more of a sense of being real, the engineers said. They know there is plenty of hard work ahead, but they are happy to see it start.

Huff said, "It's almost a sprint feeling, but it's a marathon length."

Почему капсула для парашютных тестов выглядит не так, как на графических моделях и макетах? Она стала сплюснутая и обзавелась объёмным ободом в нижней части. Это изменение в дизайне или в парашютных тестах не важно соблюдение пропорций капсулы?

First Orion Flight Hardware Headed to Florida for Final Assembly [/size]

WASHINGTON — Components of the Orion crew capsule that will orbit the Earth in a 2014 test flight are to be shipped to Cape Canaveral Air Force Station, Fla., for final assembly by the end of April, prime contractor Lockheed Martin's top human spaceflight executive said.

Lockheed recently "completed a major weld of the cylindrical section of the [Orion] body where we're welding the forward hatch sections and heat shield sections," John Karas, Lockheed Martin Space Systems vice president and general manager of human spaceflight, said March 28. "By the end of next month, we'll ship those to the Cape for final assembly of the entire first flight article Orion."

Lockheed expects to complete the Orion capsule that will fly the 2014 test flight by October 2013, Karas added.

Karas spoke as part of a panel on NASA's human spaceflight program at the 2012 Robert H. Goddard Memorial Symposium in Greenbelt, Md.

The first Orion flight, dubbed Exploration Flight Test 1, is scheduled for December 2014. An unmanned Orion will launch to space aboard a United Launch Alliance Delta 4 rocket, orbit the Earth twice, then re-enter the atmosphere and splash down somewhere in a 13-square-kilometer area off the coast of San Diego, Karas said.

During its descent, Orion will attain about 80 percent of the speed it would reach during a return from lunar space. This will give NASA an idea of how well Orion's heat shield holds up during re-entry, Karas said.

"Essentially, 11 of the 16 top risks will be retired here," Karas said of the 2014 flight, which will launch from Pad 37 at the Cape.

The Orion capsule used for Exploration Flight Test 1 will fly once more after that, Karas said, in a high-altitude launch-abort system test slated for 2015.

"This is flying a test with an Air Force-provided booster to get us up to the test point, which is matching altitude and velocity of where we would be on [the Space Launch System] during a worst-case condition to demonstrate abort capability," Larry Price, Lockheed Martin's deputy program manager for Orion, said in a March 30 phone interview. "They call it an ATB, abort-test booster, which is provided by the Air Force through NASA."

NASA is paying Lockheed about $6.8 billion to build Orion. That figure includes $375 million added to Lockheed's contract in December to cover the cost of the Delta 4 rocket that will power the 2014 test flight.

Orion's first launch atop the Space Launch System — the heavy-lift rocket NASA is developing for deep-space missions — is slated for 2017. Orion's first crewed flight is targeted for 2021.

In its 2013 budget request, NASA proposed trimming funds for Orion vehicle development to $968.5 million from the $1.14 billion approved for 2012. The move has drawn criticism from some U.S. lawmakers that NASA is deliberately slow-rolling the work.

NASA officials say the changes are necessary to keep Orion's development in sync with that of the Space Launch System, which got off to a later start.

"You will see us metering content, phasing content appropriately in order to do everything we can to hit the 2014 and 2017 timeframe," Dan Dumbacher, NASA's deputy associate administrator for exploration systems, said at the Goddard symposium.
