The Rolls-Royce LiftSystem, together with the F135 engine, is an aircraft propulsion system designed for use in the STOVL variant of the F-35 Lightning II. The complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001.

The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.

The key aspect of the X-35 that enabled STOVL operation, the SDLF system consists of the lift fan in the forward center fuselage that could be activated by engaging a clutch that connects the driveshaft to the turbines and thus augmenting the thrust from the engine's swivel nozzle.

F-35 Lightning II is a true 5th Generation trivariant, multiservice air system. It provides outstanding fighter class aerodynamic performance, supersonic speed, all-aspect stealth with weapons, and highly integrated and networked avionics.

We put the vertical lift in the F-35B Lightning II. Our LiftSystem ® is the only vertical lift technology for fighter jets in production in the world. The unrivalled performance of the LiftSystem comes in part from the latest in digital control and fan system technology to deliver responsive, precise and powerful short take-off and vertical ...

Nov 14, 2011 · The Lift Fan generates a column of cool air that produces nearly 20,000 pounds of lifting power using variable inlet guide vanes to modulate the airflow, along with an equivalent amount of thrust...

FAN DUCT HEAT EXCHANGERS/PRECOOLER Our fan duct heat exchangers and precooler systems are critical for maintaining thermal balance within the F-35. They provide efficient heat exchange by using air from the fan duct to cool hot air from the engine, helping maintain the durability and reliability of the system.

Feb 15, 2017 · The F-35 has what is called the Rolls-Royce LiftSystem. This Contains one lift fan in the middle of the aircraft, and a rotating jet exhaust to provide vertical thrust, and two rotating nozzles to provide stability.

Lift Fan Components for the F-35B Lightning II are integral parts of aircraft engine equipped with short takeoff and vertical landing (STOVL) capabilities. AEC produces the Inner Stage Vane (ISV), Outer Guide Vane (OGV), and CIAM assemblies for …
