Boeing, SpaceX readying for crew capsule abort tests
October 31, 2019 | Stephen Clark

Boeing and SpaceX are readying for launch abort tests in the coming weeks to validate the crew escape systems for the new human-rated Starliner and Crew Dragon spaceships, now scheduled to begin ferrying astronauts to the International Space Station in the first half of next year.

The abort tests are scheduled to begin as soon as next week, when Boeing plans a pad abort test of a test version of its Starliner crew capsule Monday, Nov. 4, in New Mexico. SpaceX is gearing up for a ground test-firing of the Crew Dragon's abort engines at Cape Canaveral as soon as Wednesday, Nov. 6.

"It's a very complicated dance as we're getting ready to go fly," said Kathy Lueders, who manages the commercial crew program at NASA. "We're heading into a period of final, big integrated tests ... along with tons of certification work. We tend to not say it's just paper, because it's not just paper, it's all the key things that are showing that the design is qualified and we have the vehicles at the right risk level for us to be able to fly on them."

NASA tasked Boeing and SpaceX to develop new human-rated spaceships to end U.S. reliance on Russian Soyuz spacecraft to carry astronauts to and from the International Space Station. Once they complete crewed test flights, the Starliner and Crew Dragon spacecraft will begin regular crew rotation missions to the orbiting research laboratory.

The space agency awarded commercial crew contracts to Boeing and SpaceX in 2014 valued at $4.2 billion and $2.6 billion, respectively.

After years of delays attributed to a lack of funding and technical problems, Boeing and SpaceX officials say their spaceships should be ready to carry astronauts into orbit next year. Bob Cabana, director of NASA's Kennedy Space Center, said this week he expects the capsules to be ready for crewed flights in six to eight months.

The three-hour window for Boeing's pad abort test opens at 7 a.m. MST (9 a.m. EST; 1400 GMT). A full-scale test model of Boeing's Starliner spacecraft — with a crew module and service module — will take off from a launch pad at the U.S. Army's White Sands Missile Range in New Mexico on fast-paced test of the capsule's emergency escape system.

NASA TV will broadcast the pad abort test live.

"I call this an ejection seat for a spacecraft," said Chris Ferguson, a Boeing test pilot, astronaut and director of Starliner crew and mission systems.

The pad abort test will demonstrate the Starliner can "rapidly separate itself and gain distance from the launch vehicle should something go wrong," Ferguson said Oct. 22 in a panel discussion at the International Astronautical Congress in Washington.

Ferguson will fly on the Starliner's first crewed mission, a test flight that is expected to launch next year.

During a crewed launch, emergency escape engines on the base of the Starliner's service module would propel the spacecraft off the top of its United Launch Alliance Atlas 5 rocket in the event of a failure on the launch pad at Cape Canaveral. The pad abort test set for Monday morning will prove the Starliner's escape system is up to the challenge.

"We'll go from zero speed, zero altitude, and safely demonstrate about a 1-mile-high, about a 1-mile downrange capability to remove the vehicle and safely bring it down in what will be a desert environment for the White Sands test, but what would be just off the coast of Florida if we, in fact, did have a launch pad abort.

"A lot of everything that we've been working on for the last eight years or so (is) all wrapped up in about a 90-second test, so it'll be pretty exciting," Ferguson said.

No astronauts will fly on the capsule during the pad abort test.

On a space mission, Boeing's Starliner will have 64 engines for use during launch aborts, in-orbit maneuvers and re-entry. All of the thrusters are built by Aerojet Rocketdyne.

The four biggest thrusters are the launch abort engines on the base of the Starliner's service module. In the event of an abort, each engine would immediately ignite and power up to produce some 40,000 pounds of thrust to push the spacecraft away from rocket failure on the ground or in fight.

The liquid-fueled abort engines, burning a noxious mixture of hydrazine and nitrogen tetroxide, would only fire in flight in the event of a launch emergency.

Another set of 20 service module orbital maneuvering and attitude control engines, each generating 1,500 pounds of thrust, will be used to control the capsule's orientation during a launch abort, orbital insertion after separation from the Atlas 5 rocket's second stage, and other major trajectory changes in space.

There are 28 reaction control system thrusters on the Starliner service module for smaller orbital maneuvers, and for reboosts of the space station's orbit. Twelve reusable thrusters on the Starliner crew module, each with 100 pounds of thrust, will control the ship's attitude, or orientation, during re-entry.

The Starliner capsule slated for next week's pad abort test is mounted on top of the same type of adapter that will connect the real spacecraft to the top of ULA's Atlas 5 rocket. When the craft ignites its four launch abort engines, vent doors on the adapter will open to prevent an over-pressure event.

For the pad abort test, the four launch abort engines, or LAEs, will ignite for 5.1 seconds, producing a combined 160,000 pounds of thrust to propel the spacecraft off a test stand at White Sands. The smaller orbital maneuvering and attitude control, or OMAC, thrusters will fire for 10.1 seconds to initiate a roll maneuver and govern the capsule's orientation.

Then thrusters will pulse to flip the spacecraft around and fly tail first on an arc that will take the vehicle to a maximum altitude of approximately 4,426 feet (1,349 meters) above ground level around 18.6 seconds after takeoff.

The thrusters will stop firing 17 seconds after takeoff, and a series of pilot, drogue and main parachutes will begin deploying at T+plus 20 seconds, according to Boeing.

The craft will jettison its service module at T+plus 34 seconds to fall to the ground. The crew module will then release its base heat shield, then inflate airbags to cushion the capsule's landing at White Sands around 95 seconds after liftoff.

SpaceX completed the pad abort test for its Crew Dragon spacecraft in 2015, and plans an in-flight abort test later this year at the Kennedy Space Center to verity the capsule's ability to fire off a Falcon 9 rocket after liftoff. Boeing plans to bypass such an in-flight abort demonstration.

NASA gave both companies the option to decide whether or not to conduct an in-flight abort test.

Lueders called the Boeing pad abort "a huge test for us."

"Obviously, it's going to be important for us to understand how the separation works for the CM and SM (crew module and service module), checking out the chutes, making sure that the predictions are lined up right for us," Lueders said Wednesday during a presentation to the NASA Advisory Council's human exploration and operations committee.

Boeing is in the final stages of assembling and testing two space-ready Starliner vehicles inside a former space shuttle hangar at NASA's Kennedy Space Center in Florida.

The first of the capsules is scheduled to launch as soon as Dec. 17 aboard an Atlas 5 rocket from pad 41 at Cape Canaveral Air Force Station for a week-long unpiloted test flight to the space station. That mission, called the Orbital Test Flight, will not have an active abort system, but Lueders said NASA wants to see how the Starliner performs on the abort test before going ahead with the OFT mission.

"OFT does not have the abort system on it because it's an uncrewed mission, but obviously the way the system separates and everything else will reflect on our OFT progress, so it's critical for us to get this test going and that we understand it prior to us doing rollout of the spacecraft (for OFT)," Lueders said Wednesday.

The Starliner's Crew Flight Test to the space station will follow some time in the first half of 2020, with Ferguson joined by NASA astronauts Mike Fincke and Nicole Mann.

Boeing Starliner Spacecraft to Demonstrate Critical Launch Pad Abort Capability

Boeing is preparing to put its CST-100 Starliner's launch abort system to the test on Monday, Nov. 4, at Launch Complex 32 on White Sands Missile Range in New Mexico. The test, scheduled to begin at 7 a.m. MDT (9 a.m. EDT) with a three-hour window, will demonstrate the spacecraft's ability to quickly escape the launch pad in the event of an emergency on launch day. This will be Boeing's first flight test as part of NASA's Commercial Crew Program and will help evaluate the performance of the abort system prior to missions to the International Space Station with a crew onboard.

For the demonstration, Starliner and its service module will be resting on the test stand when a zero-zero abort is declared. This means the 16.5-foot vehicle is in the launch position at zero altitude and traveling zero miles an hour. The flight test begins with ignition of Starliner's four launch abort engines (LAE), pushing the spacecraft away from the stand with a combined 160,000 pounds of thrust. About five seconds later, the LAE shut off and the orbital maneuvering and attitude (OMAC) thrusters kick in to maneuver the spacecraft into the proper orientation for parachute deployment. The vehicle is expected to reach an altitude of about 4,500 feet above the ground, and push about 7,000 feet (about 1 mile) north of the test stand.

The ascent cover and forward heat shield protecting the spacecraft's parachutes will jettison roughly 19 seconds into flight in preparation for landing. Then, drogue parachutes will deploy, prior to the main parachutes, slowing the descent of the vehicle.

After the parachutes open, the service module will separate from the crew module, followed by the base heat shield. Finally, airbags will inflate, and Starliner will touch down in the New Mexico desert approximately one-and-a-half minutes after the test began. The spacecraft service module, which has a total of 52 engines including those designed to give small directional changes in orbit, is not planned or expected to survive the test.

The zero-zero abort scenario is especially challenging because the spacecraft abort system must quickly get away from a potentially dangerous rocket, but also must gain enough altitude and distance for the parachutes to open and landing systems to be activated.

The abort test will provide Boeing and NASA with reams of data to help evaluate and verify the performance of the vehicle's abort systems – a critical capability for NASA's certification of Starliner to fly astronauts to station.

Although Boeing's abort test does not have to be completed prior to the company's uncrewed Orbital Flight Test to the space station, it is a major milestone ahead of the first flight of the new system with astronauts, called Crew Flight Test.

NASA and its commercial partners, Boeing and SpaceX, are working toward returning the capability to launch American astronauts to the space station and low-Earth orbit on American-built spacecraft from American soil.

Boeing и NASA проведут испытания системы спасения экипажа корабля CST-100 Starliner
Во время испытаний будут запущены четыре двигателя системы спасения, а также двигатели системы ориентации

НЬЮ-ЙОРК, 2 ноября. /ТАСС/. Национальное управление по аэронавтике и исследованию космического пространства (NASA) и корпорация Boeing проведут 4 ноября в штате Нью-Мексико испытания системы спасения экипажа перспективного космического корабля CST-100 Starliner. Об этом сообщила в пятницу пресс-служба NASA.

В ходе испытания будет проведена комплексная проверка всех систем, призванных обеспечить спасение членов экипажа и отвод пилотируемого отсека в сторону от пусковой установки в случае возникновения нештатной ситуации при старте ракеты-носителя. Как пояснили в пресс-службе NASA, во время испытаний будут запущены четыре двигателя системы спасения, а также двигатели системы ориентации. Они обеспечат отвод капсулы от пускового комплекса на 1600 метров. При ее спуске будет задействована парашютная система.

NASA прекратило собственные пилотируемые полеты в 2011 году после завершения программы возвращаемых кораблей Space Shuttle. С тех пор астронавты доставляются на Международную космическую станцию (МКС) российскими кораблями "Союз". В настоящее время корпорация Boeing занимается созданием перспективного космического корабля CST-100 Starliner. На орбиту Starliner будет выводить американская ракета-носитель Atlas V.

Конкурент Starliner - корабль Crew Dragon, модификация грузового Dragon, который уже перевозит грузы для МКС. Он создан компанией Space X предпринимателя Илона Маска и обладает схожими характеристиками. В космос корабль будет выводить ракета Falcon-9 производства Space X.

Начало пилотируемых полетов американских космических кораблей неоднократно переносилось на более поздний срок. Задержка на данный момент составляет уже несколько лет.

В понедельник, 4 ноября, NASA и Boeing проведут прямую трансляцию с испытания на прерывание стартовых процедур с кораблём Boeing CST-100 Starliner (Pad Abort Test) на стартовом комплексе LC-32 ракетного полигона White Sands в Нью-Мексико :f09f9a80:

Испытание назначено на 17:00 МСК (14:00 UTC / 9:00 EST) с тестовым окном в 3 часа. Начало прямой трансляция NASA запланировано на 16:50 по Москве.

Boeing Pad Abort Test является частью программы NASA CCP в рамках государственно-частного партнерства - для запуска астронавтов на американских ракетах и ​​космических кораблях с американской земли впервые с 2011 года.

Тест предназначен для проверки комплексного функционирования систем корабля, чтобы защитить астронавтов унося их от стартовой площадки в маловероятном случае возникновения чрезвычайной ситуации до старта.

Что нас ожидает ❓

В начале испытания стартуют четыре двигателя Starort, при поддержке маневровых двигателей, управляющих ориентацией, они поднимут корабль примерно на ~1,6 км над землей. Затем корабль совершит переворот и сработают вытяжные парашюты, после чего выйдут 3 основных парашюта и корабль приземлится ~ в 1,6 км к северу от испытательного стенда. Перед приземлением произойдёт отстрел щита теплозащиты и надуются специальные посадочные подушки безопасности для мягкого приземления.

После теста корабль будет возвращен на стартовый комплекс для оценки и анализа данных полученных в ходе испытания.

Боинг с самого начала не включал такой тест в свое предложение. Будут обходиться компьютерным моделированием. 

P.S. Да и прикиньте, сколько для них такой тест стоил бы, с отдельной первой ступенью Атласа, еще одним РД-180, подкалиберным адаптером, аэродинамической юбкой, и т.д.

Так и есть. Хотели сделать это подешевше, использовав бэушный первый пилотируемый Драгон, а так же трижды бэушный Фалкон. Только вот Драгон нечаянно взорвался во время тестов двигателей, что значительно сдвинуло программу вправо.

Boeing Pad Abort Test to air live on NASA TV

Marie Lewis
Posted Nov 4, 2019 at 8:01 am



Tune in to NASA TV and the agency's website at 8:50 a.m. EST today to follow live coverage of Boeing's CST-100 Starliner Pad Abort Test from Launch Complex 32 at White Sands Missile Range in New Mexico. The test is scheduled for 9 a.m. EST with a three-hour test window. Coverage will be adjusted as necessary within the window.

The Pad Abort Test is Boeing's first test flight for NASA's Commercial Crew Program, a public-private partnership with the American aerospace industry to launch astronauts to the International Space Station on American rockets and spacecraft from American soil for the first time since 2011.

The test is designed to verify that each of Starliner's systems will function not only separately, but in concert, to protect astronauts by carrying them safely away from the launch pad in the unlikely event of an emergency prior to liftoff.
