Blended Wing Body Aircraft Lifts Off

The remotely operated X-48C Blended Wing Body aircraft lifts off Rogers Dry Lake at Edwards Air Force Base, Calif., on its first test flight Aug. 7, 2012. The sub-scale technology demonstrator, modified from the prior X-48B configuration, is entering a new flight test phase in a partnership between NASA and The Boeing Company's Phantom Works research and technology division.

The aircraft, designed by the Boeing Co. and built by Cranfield Aerospace Ltd. of the United Kingdom, is flying again in partnership with NASA. The new X-48C model, which was formerly the X-48B Blended Wing Body aircraft, was modified to evaluate the low-speed stability and control of a low-noise version of a notional, future Hybrid Wing Body (HWB) aircraft design. The HWB design stems from concept studies being conducted by NASA's Environmentally Responsible Aviation project of future potential aircraft designs 20 years from now.

Edwards AFB, Calif. -- The remotely piloted X-48C aircraft successfully flew for the first time Tuesday at Edwards Air Force Base in California's Mojave Desert.

The aircraft, designed by The Boeing Co. and built by Cranfield Aerospace Limited of the United Kingdom, is flying again in partnership with NASA. The new X-48C model, which was formerly the X-48B Blended Wing Body aircraft, was modified to evaluate the low-speed stability and control of a low-noise version of a notional, future Hybrid Wing Body (HWB) aircraft design. The HWB design stems from concept studies being conducted by NASA's Environmentally Responsible Aviation project of future potential aircraft designs 20 years from now.

"We are thrilled to get back in the air to start collecting data in this low-noise configuration," said Heather Maliska, X-48C project manager at NASA's Dryden Flight Research Center. "Our dedicated team has worked hard to get the X-48C off the ground for its first flight and we are excited learning about the stability and control characteristics of this low-noise configuration of the blended wing body."

Primary changes to the C model from the B model, which flew 92 flights at Dryden between 2007 and 2010, were geared to transforming it to an airframe noise-shielding configuration. External modifications included relocating the wingtip winglets inboard next to the engines, effectively turning them into twin tails. The aft deck of the aircraft was extended about 2 feet to the rear. Finally, the project team replaced the X-48B's three 50-pound thrust jet engines with two 89-pound thrust engines.

Because handling qualities of the X-48C will be different from those of the X-48B, the project team developed flight control system software modifications, including flight control limiters to keep the airplane flying within a safe flight envelope. This will enable a stronger and safer prototype flight control system suitable for future full-scale commercial hybrid or blended wing aircraft.

"We are very pleased to begin flight tests of the X-48C," said Mike Kisska, Boeing X-48C project manager. "Working with NASA, we've successfully passed another milestone in our work to explore and validate the aerodynamic characteristics and efficiencies of the blended wing body concept."

Additionally, the upcoming flight experiments with the X-48C will help researchers further develop methods to validate the design's aerodynamics and control laws, including a goal of reducing aerodynamic drag through engine yaw control tests.

During the planned second block of flight testing this fall, NASA will test engine yaw control software incorporated in the X-48C's flight computer. This research will use asymmetric engine thrust to create yaw, or nose left or right movements, for trim and for relatively slow maneuvers.

NASA's Aeronautics Research Mission Directorate and Boeing are funding the X-48 technology demonstration research effort, which supports NASA's goals of reduced fuel burn, emissions and noise.

The X-48C retains most dimensions of the B model, with a wingspan just longer than 20 feet, and a weight of about 500 pounds. The aircraft has an estimated top speed of about 140 mph, and a maximum altitude of 10,000 feet.

The Air Force Research Laboratory, Dayton, Ohio, also is a member of the project team.

CANOGA PARK, Calif. -- Pratt and Whitney Rocketdyne has successfully completed a series of tests on a thruster destined for Boeing's Commercial Space Transportation spacecraft, designated CST-100.

Boeing is one of several companies working to develop crew transportation capabilities under the Commercial Crew Development Round 2 agreement with NASA's Commercial Crew Program. The goal of the program is to help spur innovation and development of safe, reliable and cost-effective spacecraft and launch vehicles capable of transporting astronauts to low Earth orbit and the International Space Station.

Twenty-four thrusters will be part of the spacecraft's orbital maneuvering and attitude control system (OMAC), giving the CST-100 the ability to maneuver in space and during re-entry. The thrusters also will allow the spacecraft to separate from its launch vehicle if an abort becomes necessary during launch or ascent.

"Boeing and Pratt and Whitney Rocketdyne know what it takes to develop safe systems and subsystems," said NASA Commercial Crew Program Manager Ed Mango. "They're building on the successes of their past, while pushing the envelope with next-generation ideas to create a spacecraft for low Earth orbit transportation."

During tests conducted at the White Sands Space Harbor in Las Cruces, N.M., an OMAC thruster was fired in a vacuum chamber that simulated a space-like environment of 100,000 feet. The tests verified the durability of the thrusters in extreme heat, evaluated the opening and closing of its valves and confirmed continuous combustion and performance.

"We're excited about the performance of the engine during the testing and confident the OMAC thrusters will affordably meet operational needs for safe, reliable human spaceflight," said Terry Lorier, Pratt and Whitney Rocketdyne's Commercial Crew Development program manager.

All of NASA's industry partners, including Boeing, continue to meet their established milestones in developing commercial crew transportation capabilities.

NASA also is developing the Orion spacecraft and Space Launch System (SLS), a crew capsule and heavy-lift rocket that will provide an entirely new capability for human exploration beyond low Earth orbit. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion will expand human presence beyond low Earth orbit and enable new missions of exploration across the solar system.

HUNTSVILLE, Ala. -- NASA engineers working on the new Space Launch System (SLS) can now begin developing the advanced, heavy-lift launch vehicle's flight software using newly delivered software test bed computers from Boeing.

The SLS will launch NASA's Orion spacecraft and provide an entirely new capability for human exploration beyond Earth's orbit. Designed to be flexible for crew or cargo missions, SLS and Orion will be safe, affordable, sustainable and continue America's journey of discovery from the unique vantage point of space.

"We are moving out very quickly on SLS," said Todd May, Space Launch System Program manager at NASA's Marshall Space Flight Center in Huntsville, Ala. "SLS will be the most powerful launch vehicle ever built, and it requires the most capable flight software in the history of human spaceflight. Having this avionics hardware in place early will allow the NASA SLS team and Boeing to accelerate the flight software development."

The Boeing test bed computers make it possible for NASA to begin fine-tuning the launch vehicle's software. The flight software then will be installed in the Software Integration Test Facility at Marshall and tested with other electrical hardware and software. In this facility, the SLS team can run a variety of simulations to evaluate how the vehicle will perform in space.

The final SLS flight computer that will run the flight software will have the highest processing capability available in a flight avionics computer. It is being developed by upgrading existing systems used in Global Positioning System and communication satellites.

The first test flight of the SLS is scheduled for 2017, for which the launch vehicle will be configured for a 70-metric ton lift capacity. An evolved, two-stage launch vehicle configuration will provide a lift capability of 130 metric tons to enable missions beyond Earth's orbit and support deep space exploration.

The SLS software test bed computers were developed by The Boeing Company and delivered to Marshall ahead of schedule. Availability of this test bed platform early in the engineering development phase allows more time for NASA programmers to develop the most capable flight software in the history of spaceflight.

CAPE CANAVERAL, Fla. -- The Boeing Company has successfully completed a new milestone in the development of software that will operate its Crew Space Transportation (CST) spacecraft. The company is one of NASA's partners developing commercial crew transportation capabilities to ferry U.S. astronauts to and from low Earth orbit and the International Space Station.

With the Preliminary Design Review (PDR) of its software on May 18, the company now has completed more than 40 milestones under partnerships supporting NASA's Commercial Crew Program (CCP).

"When it comes to designing a spacecraft safe enough to transport humans, software is as important as the hardware," said Ed Mango, CCP manager. "Boeing has made an excellent effort to take safety into consideration while developing critical software components of its spacecraft."

Boeing's CST-100 is designed to be a reusable, capsule-shaped spacecraft, capable of transporting up to seven people or a combination of people and cargo. It is compatible with a variety of expendable launch vehicles. Boeing has selected United Launch Alliance's Atlas V rocket for initial CST-100 test flights.

Software is essential to all operational aspects of the spacecraft, including launch, orbital maneuvering, docking with and separating from the space station, re-entry and landing. The testing is part of a NASA-funded Space Act Agreement under the second round of the agency's commercial crew development (CCDev2) activities, which could eventually lead toward human spaceflight certification of the CST-100.

The Boeing team is on schedule to complete its remaining CCDev2 milestones in the next few months, including an orbital maneuvering/attitude control engine hot fire test that will provide additional data on significant elements of the spacecraft design.

All of NASA's industry partners, including Boeing, continue to meet their established milestones in developing commercial crew transportation capabilities.
