It has a "lift fan" that looks like a hood behind the pilot, allowing air to be sucked in and through the plane - giving lift so it can take off and land.
UTC supplies a system to open and close the F35's weapons bay door, while Moog makes hugely complex parts for the Rolls-Royce lift fan engine unit.
PATENTED LIFT FAN SYSTEM Lockheed Martin patented JSF shaft-driven lift fan system produces 60 per cent more vertical lift in the STOVL mode with a cooler ground footprint than direct lift systems
The problem of transition maneuvers has been studied for different types of UAVs, including a fixed-wing aircraft equipped with a thrust vector engine and lift fan [1-3], tilt-rotor aircraft [4-7], tail-sitter aircraft [8, 9], ducted-fan VTOL aircraft [10, 11], and tilt-wing aircraft [12,13].

ABOARD THE USS WASP, Muharram 2, 1433, Nov 27, 2011, SPA -- The 16-ton fighter jet slowed to a stop off the warship's port beam, where it hovered like a floating rock as thousands of pounds of thrust from its engine and lift fan stirred up a cloud of mist from the Atlantic Ocean 100 feet below, according to Reuters.
The peak temperatures were found in a C-shaped zone that mimics the shape of the turbine blade plenum around the lift fan (mostly from 150 to 180[degrees] F but with the peak along the pod side reaching 250[degrees] degrees F).
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.
