Pushing 41,100 above the pit.

Lockheed Martin reported the first F-35B short takeoff/vertical landing (Stovl) stealth fighter has been tested in vertical landing mode over a special 'hover pit'. The test was designed to confirm that the single Pratt & Whitney F135 engine, driving a Rolls-Royce lift fan, was capable of providing the required 40,500 lbs of vertical thrust detailed in the programme's requirements. The Lightning II Stovl's engine punched out 41,100 lbs of thrust during the test, proving Pratt & Whitney's F135 engine is thus far the most powerful powerplant to be flown in a jet fighter. The hover pit test, as seen above, finds the aircraft anchored to the floor above a metal grate, which separates the aircraft from the ground effect and enables it to simulate free flight. An array of sensors measure the thrust and the aircraft's response to pilot controls.
