NASA Considers Five X-Plane Airline Concepts

September 19, 2017

NASA is evaluating five proposed designs for an X-Plane that will test new technologies to help airliners fly more quietly, burn less fuel and release fewer emissions than aircraft flying today.













The X-Plane concept designs aim to address NASA’s goals for 2035, namely, a 60 to 80 percent reduction in fuel consumption, greater than 80 percent reduction in emissions and reducing noise by more than 50 percent.

“As of now, the plan is to begin implementation of the first subsonic X-Plane project around 2020, leading to a first flight in 2026,” said Fay Collier, NASA’s associate director for flight strategy. The five designs that will move forward were proposed by Boeing, Lockheed Martin, Aurora Flight Sciences and Dzyne Technologies.

Boeing proposed two designs, a blended-wing-body aircraft with the jet engines placed on top of the fuselage to shield the noise, and an aeroplane with a truss-brace that could support a long, narrow wing.

Aurora’s Double Bubble D8 features two hull sections fused together, and a vertical stabilizer with a two-fin T-tail.

Dzyne proposed a blended-wing-body design similar to Boeing’s but for a regional-airliner size aircraft.

Lockheed Martin’s design features a hybrid wing body with twin engines mounted on pylons attached to and trailing the wing.
