A new fixture on the Cape Canaveral skyline began rising Tuesday, with the placement of the first of seven segments for a 200-foot-tall crew access tower at the Atlas 5 rocket's seaside launch pad for astronauts boarding Boeing's new commercial CST-100 Starliner spaceship.
The first two tiers of the tower transferred to the Atlas 5 rocket's Complex 41 launch pad Sept. 9, and a giant crane at the launch site positioned the first segment over the structure's concrete foundation Tuesday, according to a United Launch Alliance spokesperson.
Construction crews assembled the seven tiers at a nearby worksite beginning earlier this year, and now attention turns to stacking the tower at Complex 41.
Astronauts flying into space aboard the CST-100 Starliner crew capsule will ride an elevator up the tower and then crawl into the spacecraft through a climate-controlled enclosure called a white room.
Boeing is developing the CST-100 Starliner spacecraft under contract to NASA, which awarded the aerospace giant an agreement worth up to $4.2 billion to finish certification of the crew capsule and fly up to six full-up crew ferry flights between Earth and the International Space Station.
NASA signed a similar contract SpaceX worth up to $2.6 billion for the Crew Dragon spaceship outfitted for humans. SpaceX's crewed flights will take off on Falcon 9 rockets a decommissioned space shuttle launch pad currently being modified for the purpose.
The commercial crew program will end U.S. reliance on Russian Soyuz spacecraft to carry crews to the space station.
Engineers are using down time in the Atlas 5 rocket's busy launch manifest to build up the crew access tower at Complex 41, according to Howard Biegler, head of human launch services at ULA, the Boeing-Lockheed Martin joint venture which builds and operates the Atlas 5.
"All seven tiers, which make up the center core of the crew access tower, are fully constructed," Biegler said in an interview with Spaceflight Now. "The towers are fully outfitted. We've got stairwells, all the piping, fire extinguishers, elevator shafts, you name it."
Construction crews at the launch pad, situated a half-mile fr om the Atlantic shoreline, have built up a crane to lift the tower segments.

The launch pad will not have a permanent tower until the crew access structure is erected. The Atlas 5 rocket is built up on a mobile platform inside a nearby vertical integration facility, then rolled out to the launch pad the day before liftoff.
Biegler said the plan calls for all seven segments to be hoisted by the time of the Atlas 5's scheduled launch of a new GPS navigation satellite Oct. 30. Some of the tiers will go up before the Atlas 5's next mission, which is set for Oct. 2 with a Mexican communications satellite, and ground teams will add the rest before the Oct. 30 launch.
"After our GPS launch at the end of October, all of our outboard steel which makes the top part of the tower for storing the crew access arm, emergency egress and other equipment will be added," Biegler said.
The stacking of the crew access tower comes after teams poured 300 cubic yards of concrete for the structure's foundation just to the northwest of where the Atlas 5's mobile launch platform parks over the launch pad's flame trench, according to John Mulholland, vice president and program manager for Boeing's commercial crew program.
While workers poured the foundation, a team nearby constructed the seven 28-foot-tall 20-by-20 foot sections for the crew access tower.
Biegler said the structure will be completed by January.
"Then we'll start running cables and outfitting it," he said.
A 42-foot-long crew access arm is taking shape at a construction yard in nearby Oak Hill, Florida. The appendage will connect the tower to the CST-100 Starliner mounted atop the Atlas 5 rocket, allowing astronauts to board the capsule in the final hours of the countdown.
Located about 172 feet up the 20-story tower, the arm will swing away after ground teams close the Starliner hatch, clearing the way for liftoff.
"We've got the torque tube, the structural arm, the white room and the environmental seal, and the drive system, which we call the hydraulic drive system, will be integrated on a test stand and we'll run it through its paces," Biegler said. "That's a critical path item. When we bring it out to Complex 41 in the June timeframe of next year, we want to know exactly wh ere it's got to be positioned on the tower, and know that everything works and the timing works perfectly."
ULA and Boeing managers are working out the details of how to load the astronauts into the CST-100 Starliner.
Engineers evaluated Apollo- and shuttle-era white rooms, including artifacts on display at the Kennedy Space Center Visitor Complex, when designing the Starliner access arm.
"We've got an environmental seal on the end of it that is 7 feet by 5 feet by 5 feet on the end of (the white room)," Biegler said. "If you take that into consideration, we're actually bigger than shuttle (white room), but for the most part, it's comparable."
A closeout crew similar to the team that strapped astronauts into the space shuttle will be at the launch pad to help crew members into the CST-100 Starliner. The ground team will likely be a mix of ULA, Boeing and NASA personnel, but the exact makeup has not been finalized, according to Biegler.
"We're going to have as few people out there as we need to make it efficent because we want to be able to get this done in a quick manner, and get them out," Biegler said.
"It's also pretty hazardous," said Tony Taliancich, director of ULA's east coast operations. "We don't want to take any more risks than we need to take. We'll have a fully loaded vehicle with hydrogen and oxygen, and be ready to launch at that point."
The Atlas 5 launch team will fuel the rocket with propellants before the astronauts arrive at the pad. A built-in hold at T-minus 4 minutes, which usually lasts a few minutes, will be extended up to three hours to give the crew time to get into the capsule.
"In our normal process, we're within four minutes of launching at that point, so we're just waiting for the astronauts to get on-board," Taliancich said.
The CST-100 Starliner can carry up to seven astronauts, but the capsule's standard mission will likely include a crew of four plus supplies for the space station.
Another feature of the crew access tower will be a slidewire escape system similar to the emergency egress baskets used at the space shuttle launch pads.
Boeing's capsule will fly on a version of the Atlas 5 with two solid rocket boosters, a dual-engine Centaur upper stage, and an emergency detection system to detect faults in flight and trigger an abort, if necessary.
Officials said all of the crew access tower construction should be completed by late 2016, in time for the first uncrewed CST-100 Starliner test flight scheduled for May 2017, and the first human demonstration mission in September 2017.

Конечно

silentpom · 16.09.2015 15:30:16

я почему-то решил, что они ТТУ не будут использовать. А дельта для него в хэви варианте или тоже с ТТУ?

New Crew Access Tower Construction Progresses in Cape Canaveral

By Steven Siceloff,
NASA's Kennedy Space Center, Fla.
It took only 35 days to build the main column of a new fixture to the skyline along the Florida Space Coast. The 200-foot-tall Crew Access Tower at Cape Canaveral Air Force Station in Florida will meet the unique needs of astronauts and ground crews at Space Launch Complex 41, or SLC-41, where Boeing will launch its CST-100 Starliner spacecraft on Atlas V rockets operated by United Launch Alliance, also known as ULA.
"We spent a lot of time with conceptual designs and with the human elements, which is very important for a project of this nature," said Howard Biegler, ULA's Launch Operations lead for Human Launch Services. "Building a structure is one thing, but building it so that it's useful, that it provides a safe environment for the people who are going to be called to use this system is the hard part."
The structure features wider, more open areas than NASA's previous crew access towers, providing more room and comfort for astronauts who will walk around the area in pressure suits and possibly wearing helmets, and in emergency cases, walk through walls of water fr om fire suppression sprinklers. An escape system for the ground support teams and flight crews will be added to quickly move people from the top of the tower to the safety of an evacuation vehicle in less than a minute.
The tower location is unique, as well. Since 1968, all astronauts launched from the United States have flown exclusively from Launch Pads 39A and B at NASA's adjacent Kennedy Space Center.
Construction at the pad began in September when the first of seven steel tiers was trucked from four miles away wh ere it was built and then placed atop a strengthened concrete foundation at SLC-41.
Built with many of the features already in place such as stairways, cable trays and blast shielding, each tier was designed to fit atop the other perfectly to reduce construction time at the pad. That's because ULA kept the pad operational so it could continue to launch Atlas V missions in between stages of tower construction.
"We have certainly changed the landscape out here," Biegler said. "The day the first tier physically made contact with the concrete and was bolted up brought a new level of reality to the project."
More work is ahead to complete the tower, but the main column stands in place as a herald for the next generation of human spaceflight in America. Steel sections branching off the main column will be in place by mid-January then the tower will be fitted with elevators, data lines and other elements. The tower's steel frame will weigh about 966,000 pounds when it's completed in fall 2016.
In late October, the structure's crew access arm was connected to the White Room, which will serve as the final corridor astronauts will pass through as they enter the Starliner spacecraft standing atop the Atlas V. The two components will be tested together extensively off-site before they are trucked to the launch complex and installed next summer.
Boeing anticipates launching the first flight test of its Starliner spacecraft carrying astronauts in 2017, but will use the tower before that time in the preparation for an earlier flight test without a crew aboard.
"It takes a lot of people working hard together to get any spacecraft into orbit successfully, and that's doubly true for a new spacecraft being built for humans," said Mike Burghardt, director of Launch Segment Integration for Boeing's Commercial Crew Program. "The Starliner will feature modern, high reliability components to significantly increase crew safety and we back that up with robust launch system, including this Crew Access Tower."
All the work is adding to the feeling that a new dawn of spaceflight is nearing as NASA's Commercial Crew Program and its partners Boeing and SpaceX continue development on systems that will carry up to four astronauts at a time to the International Space Station. With commercial spacecraft transportation, NASA plans to add an additional crew member to the station, effectively doubling the crew time dedicated to research on the orbiting laboratory.
While Boeing and SpaceX focus on transportation opportunities in low-Earth orbit, NASA is moving ahead with its Space Launch System and Orion spacecraft that will take off from Kennedy's Launch Pad 39B to carry out deep-space exploration missions that will advance the agency's journey to Mars.
