Most people don't know this, but NASA doesn't only work in exploring space. Its contribution to airplane technology—National Aeronautics and Space Administration—has been crucial to the development of safer, faster, more efficient travel. These are their coolest future concepts—some of which could enter service as soon as 2025.
These concepts have been developed working with private companies like Lockheed Martin, Northrop Grumman, and Boeing:
This concept of an aircraft that could fly at supersonic speeds over land is being used by researchers, especially at NASA's Langley Research Center, to continue to test ideas on ways to reduce the level of sonic booms. Its technologies – the F-100-like propulsion system, a tail blister, and the overall shape – are combined to achieve a lower target perceived decibel level.
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.
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 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.
