X-57 Maxwell Aircraft, United States of America

Maxwell aircraft

The X-57, also known by nickname Maxwell, is an experimental aircraft being developed by National Aeronautics and Space Administration (NASA).

Named after Scottish physicist James Clerk Maxwell, the aircraft is being developed with an aim to demonstrate technology to reduce fuel usage, emissions and noise.

NASA displayed the first designated X-57 plane at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition in June 2016.

The first flight tests on the X-57 Maxwell aircraft for initial modifications are expected to commence in Spring 2018. The experimental wing integration for the aircraft with electric motors and a new wing technology will be completed in 2019.

NASA plans to develop five larger X-planes for commercial production. The first X-plane, known as X-1, was introduced in 1947 and was the first aircraft to fly faster than the speed of sound.

Design, features and development of X-57 Maxwell

The research on X-57 plane began as part of NASA's scalable convergent electric propulsion operations research (SCEPTOR) project. The plane's design was initiated under NASA's leading-edge asynchronous propeller technology.

Empirical Systems Aerospace (ESAero) was selected as prime contractor for the Convergent Electric Propulsion Technology (CEPT) in October 2014.The aircraft is being developed as first manned X-plane by modifying an Italian-procured and designed Tecnam P2006T twin-engine light aircraft, which was shipped from Naples, Italy, and arrived at ESAero facility at Oceano Airport in July 2016. The P2006T aircraft underwent inspection, and was also followed by weight and balance testing.

The final inspection of X-57 plane is expected to be completed at ESAero facility soon, following which it will be transported to Scaled Composites in Mojave, California, to carry out further modifications into a fully-electric airplane.

The wing of the aircraft was designed at NASA's Langley Research Center in Virginia, and fabricated by Xperimental in San Luis Obispo, California. NASA's Armstrong Flight Research Center and Langley Research Center are working on the development of distributed electric propulsion for the X-57. The electric motors for the aircraft are developed by Joby Aviation in Santa Cruz, California.

The additional airflow over the newly developed wings with added eclectic motors generates greater lift and will allow a narrower wing. The wing of the aircraft will be constructed with composite carbon fibre, which will be integrated onto the fuselage once the electric power validation flights are complete.

The fuselage and cockpit are also based on those of Tecnam P2006T.

X-57 Maxwell aircraft engine and performance details

"The first X-plane, known as X-1, was introduced in 1947 and was the first aircraft to fly faster than the speed of sound."

The X-57 Maxwell is powered by 14 electric motors including 12 on the leading edge, which will be used for take-offs and landings, and one larger motor on each wing tip, which will be used for cruise altitude.

The aircraft will be powered by a battery system developed by Electric Power Systems in the City of Industry in California. The electric-powered aircraft requires five times less energy to fly a light aircraft at a cruise speed of 282km/h (175mph).

The aircraft can accommodate up to two passengers and will have a range of approximately 160km (100mi) and a maximum flight time of one hour.
