How does the f35 lift fan work?
The lift fan, located towards the front of the aircraft, acts as a counterbalance by using two counter-rotating blisks. Unheated engine bypass air is then diverted through nozzles mounted on the wings of the aircraft, called roll posts, in order to allow roll control.
Who makes the engine for the F-35?

How does a Rolls Royce LiftFan work?
The Rolls-Royce LiftSystem, which includes the LiftFan located behind the cockpit and the swivel module at the tail, produces lift by directing thrust downward to overcome the weight of the aircraft. It produces a total vertical lifting thrust of more than 40,000 pounds, which is about 10,000 pounds more than the F-35B weighs.
What kind of engine does Rolls Royce use?
The system is a descendant of the Pegasus engine, comprised of the Rolls‑Royce LiftFan ®, Driveshaft, 3 Bearing Swivel Module (3BSM) and Roll Posts. Rolls‑Royce has been the industry leader in short take-off and vertical landing (STOVL) technology for 60 years.
Which is the most powerful Rolls Royce Lift System?
The following indicates the component thrust values of the system in lift mode: In comparison, the maximum thrust of the Rolls-Royce Pegasus 11-61/F402-RR-408, the most powerful version which is used in the AV-8B, is 23,800 pounds-force (106 kN). The weight of the AV-8B is about 46% of the weight of the F-35B .
How much weight does the Rolls Royce lean plant lift?
It produces a total vertical lifting thrust of more than 40,000 pounds, which is about 10,000 pounds more than the F-35B weighs. During vertical takeoffs or landings, doors above and below the lift fan open, and a clutch connecting the lift fan to the engine driveshaft engages.
