NASA moves Environmentally Responsible Aviation project into next phase of research with 8 large-scale technology demonstrations

8 January 2013

NASA has selected eight large-scale integrated technology demonstrations to advance aircraft concepts and technologies for reducing the impact of aviation on the environment over the next 30 years.

The demonstrations, which are part of by NASA’s Environmentally Responsible Aviation (ERA) Project, will focus on five areas: aircraft drag reduction through innovative flow control concepts; weight reduction from advanced composite materials; fuel and noise reduction from advanced engines; emissions reductions from improved engine combustors; and fuel consumption and community noise reduction through innovative airframe and engine integration designs.

The selected demonstrations are:

  • Active Flow Control Enhanced Vertical Tail Flight Experiment: Tests of technology that can manipulate, on demand, the air that flows over a full-scale commercial aircraft tail.

  • Damage Arresting Composite Demonstration: Assessment of a low-weight, damage-tolerant, stitched composite structural concept, resulting in a 25% reduction in weight over state-of-the-art aircraft composite applications.

  • Adaptive Compliant Trailing Edge Flight Experiment: Demonstration of a non-rigid wing flap to establish its airworthiness in the flight environment.

  • Highly Loaded Front Block Compressor Demonstration: Tests to show Ultra High Bypass (UHB) or advanced turbofan efficiency improvements of a two-stage, transonic high-pressure engine compressor.

  • 2nd Generation UHB Ratio Propulsor Integration: Continued development of a geared turbofan engine to help reduce fuel consumption and noise.

  • Low Nitrogen Oxide Fuel Flexible Engine Combustor Integration: Demonstration of a full ring-shaped engine combustor that produces very low emissions.

  • Flap and Landing Gear Noise Reduction Flight Experiment: Analysis, wind tunnel and flight tests to design quieter flaps and landing gear without performance or weight penalties.

  • UHB Engine Integration for a Hybrid Wing Body: Verification of power plant and airframe integration concepts that will allow fuel consumption reductions in excess of 50 percent while reducing noise on the ground.

With these demonstrations we will take what we’ve learned and move from the laboratory to more flight and ground technology tests. We have made a lot of progress in our research toward very quiet aircraft with low carbon footprints. But the real challenge is to integrate ideas and pieces together to make an even larger improvement. Our next steps will help us work towards that goal.

—Fay Collier, ERA project manager based at NASA’s Langley Research Center

The Environmentally Responsible Aviation Project was created in 2009 and is part of NASA’s Aeronautics Research Mission Directorate’s Integrated Systems Research Program.

During its first phase, engineers assessed dozens of broad areas of environmentally friendly aircraft technologies and then matured the most promising ones to the point that they can be tested together in a real world environment in the second phase. Those experiments included nonstick coatings for low-drag wing designs, laboratory testing of a new composite manufacturing technique, advanced engine testing, and test flights of a remotely piloted hybrid wing body prototype.

Each of the demonstrations, which are scheduled to begin this year and continue through 2015, is expected to include selected industry partners, many of which will contribute their own funding.

ERA is one of many NASA aeronautics research efforts to develop technologies to make aircraft safer, faster, and more efficient and to help transform the national air transportation system. That research is being conducted at NASA Langley; NASA’s Ames Research Center at Moffett Field, Calif.; NASA’s Dryden Flight Research Center at Edwards Air Force Base, Calif.; and NASA’s Glenn Research Center in Cleveland.

Yes, these could become NASA's short term (5-year priority) objectives financed from delayed space projects. It could have a more positive impact on the environment than loading the close space with debris.
