Engineers for the first time powered up the CST-100 Starliner spacecraft that will fly Boeing's inaugural flight test of the next-generation spacecraft. Working inside Boeing's Commercial Crew and Cargo Processing Facility at NASA's Kennedy Space Center in Florida, the test team activated the flight avionics system for the Starliner known as Spacecraft 1. The system is the same astronauts will use for all Starliner missions.

The avionics is the complex suite of equipment and software that work together to maneuver the spacecraft in orbit, conduct the rendezvous and docking with the International Space Station and communicating with Mission Control on the ground. Whether under manual control by the crew or in automatic mode, the flight computers have to work seamlessly with the thrusters, guidance and navigation system and other subsystems to perform the mission and then return back to Earth safely.

The Starliner is being built as an upper half and lower half that will be bolted together following successful systems testing. Once completed, Spacecraft 1 will be launched without a crew on a flight test to demonstrate its capability to abort a mission from the launch pad in the unlikely event of an emergency. Later flight tests will demonstrate Starliners in orbital missions to the station without a crew, and then with astronauts aboard. The flight tests will preview the crew rotation missions future Starliners will perform as they take up to four astronauts at a time to the orbiting laboratory in order to enhance the research taking place there.

Commercial Crew on tight but achievable timeline for crewed flights in 2018
April 7, 2017 by Chris Gebhardt

 

The long and arduous process of achieving commercial crew transportation services to space is closing in on an important milestone. At a recent update to the NASA Advisory Council, NASA's commercial crew transportation services program manager discussed numerous aspects to SpaceX and Boeing's progress over the last few months and revealed that, while the timeline is tight, the two companies are on track for their scheduled crew demo flights of Dragon and Starliner in 2018.

Boeing – Starliner's progress:

Спойлер

According to the accompanying presentation for CCP to the NAC, Boeing has completed the Critical Design Reviews for both their ascent and entry suit systems for the crew as well as the base heat shield for the CST-100 Starliner vehicle.



Since the last NAC update, Boeing has completed wind tunnel testing of the launch vehicle adapter skirt, conducted International Docking Adapter and NASA Docking System testing at the Johnson Space Center, successfully dropped tested the parachutes and tested their deployment sequence, hot fired the launch Abort Engines with their new propellant valves, completed acceptance testing and RL-10 hot fire of the CFT engines, and performed quality testing at the Langley Research Center for the landing airbag system.

Moreover, the version 8.0 software release has been completed, gaining specific note fr om Ms. Lueders who praised Boeing, saying that "It's one of the few programs I've seen where the software is actually running ahead of the hardware."



In terms of hardware, the Starliner Structural Test Article is at Huntington Beach, California, wh ere proof pressure testing was completed last December.

At the C3PF, the former OPF-3, at the Kennedy Space Center, Spacecraft 1's Crew Module upper and lower dome outfitting work is on track to support power on testing this year.

The Spacecraft 1 Service Module's structural panels have also arrived at the space center.

Moreover, Spacecraft 2's upper and lower dome outfitting has begun in C3PF, and Spacecraft 3 is "progressing across the supply base," notes the CCP presentation to the NAC.

"So there's a lot of hardware in flow," stated Ms. Lueders. "But we need a lot of hardware in flow to be able to meet our schedule."

At present, Boeing's uncrewed demonstration flight is slated for June 2018 ahead of the crewed demo flight in August 2018.

Aerojet Rocketdyne Successfully Completes Qualification Tests on Reusable Engine to Support Next Era of Human Spaceflight from the United States

SACRAMENTO, Calif., April 20, 2017 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), has successfully completed hot-fire qualification tests of an engine that demonstrates the ability to meet reusability requirements for Boeing's Crew Space Transportation (CST)-100 Starliner crew module propulsion system. The tests were conducted on Aerojet Rocketdyne's MR-104J hydrazine monopropellant engine in Redmond, Washington. For NASA service missions to the International Space Station, Boeing's Starliner spacecraft will carry up to four astronauts and time-critical scientific research.

"Our engineers have incorporated a unique design that will allow the MR-104 engine to be used on multiple missions, providing the reliability, cost-efficiency and reusability our customer needs to be competitive in the current commercial space environment," said Aerojet Rocketdyne CEO and President Eileen Drake. "We look forward to delivering the engines for the crew module and continuing our proud heritage of enabling astronauts to fly to the International Space Station from U.S. soil."

The Starliner crew module propulsion system will use 12 MR-104J engines for reaction control to orient the vehicle during re-entry into the Earth's atmosphere. Prior to re-entry, attitude control is provided by the Service Module Engines, also provided by Aerojet Rocketdyne.

The MR-104J, designed by Aerojet Rocketdyne, was developed and tested under the company's Commercial Crew Transportation Capability (CCtCap) subcontract to Boeing. Similar to other reaction control system engines, the MR-104J includes additional features to increase redundancy that meet critical requirements and improved strength to withstand multiple shocks at operating temperatures. The engine upgrades also provide reusability for Boeing as it certifies Starliner crew modules for multiple missions.

Under the CCtCap subcontract to Boeing, Aerojet Rocketdyne will provide propulsion system hardware that includes Crew Module Reaction Control engines; Launch Abort Engines, Orbital Maneuvering and Attitude Control thrusters, and Service Module Reaction Control System thrusters. Boeing will assemble propulsion hardware into the Starliner spacecraft at its Commercial Crew and Cargo Processing Facility at NASA's Kennedy Space Center in Florida.

Every aspect of NASA's Commercial Crew Program spacecraft are being tested for the journey to and from the International Space Station to meet the agency's mission and safety requirements. Testing from Boeing and SpaceX demonstrates how the systems perform in flight-like scenarios. Engineers working with Boeing's CST-100 Starliner spacecraft recently lab tested their seat design focusing on how the spacecraft seats protect the head, neck and spine of the astronauts for the 240-mile descent from space.

The company incorporated test dummies for a detailed analysis of impacts on a crew returning to Earth. The human-sized dummies were secured in their crew module seats for 30 drop tests at varying heights, angles, velocities and seat orientations, all in an effort to mimic actual landing conditions. To simulate the return, the seats were suspended inside a metal frame and dropped to land on honeycomb-like panels at the base of the test stand meant to function similarly to the Starliner's landing airbags. The dummies were equipped with sensitive instrumentation to measure the impacts and high-speed cameras were used to capture the footage for further analysis. When the Starliner returns to Earth from the International Space Station, the spacecraft will be slowed by using a choreographed parachute system and will then land on large airbags to further soften the landing in the western region of the United States. The company also will test a full-scale mock-up of the Starliner spacecraft using male and female test dummies at NASA's Langley Research Facility.
The Starliner spacecraft is being developed in partnership with NASA's Commercial Crew Program. NASA is investing in private industry with a goal of resuming human spaceflight to and from low-Earth orbit from the United States. Starliner will launch on a United Launch Alliance Atlas V rocket at Space Launch Complex 41 to fly up to four astronauts to the space station for NASA missions. NASA also has partnered with SpaceX to develop the Crew Dragon spacecraft and the company's Falcon 9 rocket. The SpaceX design calls for the Crew Dragon to return with a splashdown in the ocean. Both companies will launch from Florida's Space Coast. Together, the private companies will provide regular and reliable crew transportation to and from the microgravity outpost for NASA.
