These eco-friendly planes have been dubbed ‘greener flying machines for the year 2025Our ability to fly at supersonic speeds over land in civil aircraft depends on our ability to reduce the level of sonic booms. NASA has been exploring a variety of options for quieting the boom, starting with design concepts and moving through wind tunnel tests to flight tests of new technologies. This rendering of a possible future civil supersonic transport shows a vehicle that is shaped to reduce the sonic shockwave signature and also to reduce drag. (Image & Text Courtesy: NASA)
The "double bubble" D8 Series future aircraft design concept comes from the research team led by the Massachusetts Institute of Technology. Based on a modified tube and wing with a very wide fuselage to provide extra lift, its low sweep wing reduces drag and weight; the embedded engines sit aft of the wings. The D8 series aircraft would be used for domestic flights and is designed to fly at Mach 0.74 carrying 180 passengers 3,000 nautical miles in a coach cabin roomier than that of a Boeing 737-800. The D8 is among the designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced aircraft that could enter service in the 2030-2035 timeframe.

This future aircraft design concept comes from the research team led by GE Aviation. Much lighter and more aerodynamic than current aircraft with the same capacity, the 20-passenger aircraft would reduce fuel consumption and noise and enable business jet-like travel between more than 1,300 airports. It features ultra-quiet turboprop engines, virtual reality windows and is designed to fly at Mach 0.55 for 800 nautical miles. This GE aircraft is among the designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced aircraft that could enter service in the 2030-2035 timeframe..

The Silent Efficient Low Emissions Commercial Transport, or SELECT, future aircraft design comes from the research team led by Northrop Grumman Systems Corporation. Deceptively conventional-looking, the concept features advanced lightweight ceramic composite materials and nanotechnology and shape memory alloys. In addition to being energy efficient and environmentally friendly, the SELECT improves the capacity of the future air transportation system because it can be used at smaller airports and make them more effective. It is designed to fly at Mach 0.75 carrying 120 passengers 1,600 nautical miles. The SELECT is among the designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced aircraft that could enter service in the 2030-2035 timeframe.

The Subsonic Ultra Green Aircraft Research, or SUGAR, Volt future aircraft design comes from the research team led by The Boeing Company. The Volt is a twin-engine concept with a hybrid propulsion system that combines gas turbine and battery technology, a tube-shaped body and a truss-braced wing mounted to the top of the aircraft. This aircraft is designed to fly at Mach 0.79 carrying 154 passengers 3,500 nautical miles. The SUGAR Volt is among the designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced aircraft that could enter service in the 2030-2035 timeframe.

This computer-generated image shows a possible future "flying wing" aircraft, very efficiently and quietly in flight over populated areas. This kind of design, produced by Northrop Grumman, would most likely carry cargo at first and then also carry passengers. This design is among those presented to NASA at the end of 2011 by companies that conducted NASA-funded studies into aircraft that could enter service in 2025. (Image & Text Courtesy: NASA)
This future aircraft design concept for supersonic flight over land comes from the team led by the Lockheed Martin Corporation. The team used simulation tools to show it was possible to achieve over-land flight by dramatically lowering the level of sonic booms through the use of an "inverted-V" engine-under wing configuration. Other revolutionary technologies help achieve range, payload and environmental goals. This concept is one of two designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced supersonic cruise aircraft that could enter service in the 2030-2035 timeframe.

The "Icon-II" future aircraft design concept for supersonic flight over land comes from the team led by The Boeing Company. A design that achieves fuel burn reduction and airport noise goals, it also achieves large reductions in sonic boom noise levels that will meet the target level required to make supersonic flight over land possible. This concept is one of two designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced supersonic cruise aircraft that could enter service in the 2030-2035 timeframe.

Boeing s advanced vehicle concept centers around the familiar blended wing body design like the X-48. What makes this design different is the placement of its Pratt & Whitney geared turbofan engines on the top of the plane s back end, flanked by two vertical tails to shield people on the ground from engine noise. The design also uses other technologies to reduce noise and drag, and long-span wings to improve fuel efficiency. This design is among those presented to NASA at the end of 2011 by companies that conducted NASA-funded studies into aircraft that could enter service in 2025 (Image & Text Courtesy: NASA)
Northrop Grumman s concept is based on the extremely aerodynamic "flying wing" design. The four Rolls Royce engines are embedded in the upper surface of the wing to achieve maximum noise shielding.
