One Aviation announced recently that it had successfully flown the proof-of-concept experimental test aircraft N990NE, which was modified to test the new wing shape being used for the EA700 model currently in development.
This aircraft still retains the E500 fuselage, engines and stabilizers, but has had the wing modified to match the length and shape expected of the EA700 wing. Changes to the wing include the overall 4ft increase in wingspan and reshaping of the inboard wing airfoils and planform. The expected shape of the production EA700 wing tips have not been included in this modification, however.
“This is a key milestone in the path to making a very good airplane a great airplane”, said One Aviation chairman Alan Klapmeier. “The One Aviation team has worked hard to achieve this key milestone for the EA700 proof-of-concept wing.”
The flight lasted approximately 1.5 hours; handling qualities were evaluated during transitions between all configurations; and maneuvering and basic aircraft flying qualities were evaluated at altitudes up to 15,000ft. The plane performed flawlessly and all test condition results were as expected.
The aircraft felt “very solid” said Jerry Chambers, chief test pilot and pilot-in-charge for the flight, who added that it was “a testament to the efforts of the engineering and build teams.”
