F-35A achieves max angle of attack

The F-35 Joint Strike Fighter flight test program has accomplished another milestone with a conventional takeoff and landing (CTOL) F-35A achieving the jet’s maximum 50-degree angle of attack.

The goal was reached in only four test flights and breaks the previous 20 degree limit imposed on test aircraft until controllability was proven.

Lockheed Martin said the ability to rapidly progress to the maximum angle of attack indicates a sound aerodynamic and flight control system design. High angle of attack tests will continue on the F-35A for several months, according to the manufacturer, to further test the capabilities of design loadings and the flight control system.

High angle of attack testing will continue on the F-35A for the coming months to prove out dsign loadings and flight systems. (Lockheed Martin)
