NASA's superb futuristic aircraft designs
Our 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.
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.
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.
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. The company used its expertise in building
military planes without a stabilizing tail to propose this design for
the commercial aviation market.
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.
Lockheed Martin's advanced
vehicle concept proposes a box wing design, which is now feasible thanks
to modern lightweight composite (nonmetallic) materials, landing gear
technologies and other advancements. Its Rolls Royce Liberty Works Ultra
Fan Engine achieves a bypass ratio (flow of air around engine compared
to through the engine) nearly five times greater than current engines,
pushing the limits of turbofan technology to maximize 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.
This computer rendering shows
AMELIA (Advanced Model for Extreme Lift and Improved Aeroacoustics), a
possible future hybrid wing body-type subsonic vehicle with short
takeoff and landing capabilities. Produced through a three-year NASA
Research Announcement grant with the California Polytechnic State
Institute, AMELIA's ability for steeper ascents and descents could
reduce community noise levels on takeoff and landing. A model of this
configuration is scheduled for testing in a NASA wind tunnel in the fall
of 2011.
This artist's concept shows a
possible future subsonic aircraft using a boxed- or joined-wing
configuration to reduce drag and increase fuel efficiency. This design
of an aircraft that could enter service in the 2020 timeframe is one of a
number of designs being explored by NASA with teams of researchers from
industry and universities.
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.
The Hybrid Wing Body H-Series
future aircraft design concept comes from the research team led by the
Massachusetts Institute of Technology.
This design is suitable for intercontinental flights and larger
passenger loads similar to a Boeing 777. It features embedded engines
using variable area nozzles with thrust vectoring, noise shielding
thanks to the fuselage and other technologies, and advanced onboard
vehicle health monitoring systems. This aircraft is designed to fly at
Mach 0.83 carrying 354 passengers 7,600 nautical miles.
The H Series 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.
Three industry teams spent 2011
studying how to meet NASA's goals for making future aircraft burn 50
percent less fuel than aircraft that entered service in 1998, emit 75
percent fewer harmful emissions; and shrink the size of geographic areas
affected by objectionable airport noise by 83 percent.
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.
