Liftfan power for JSF



The LiftFan, a 50-inch, two-stage counter-rotating fan capable of generating more than 20,000lbf of thrust, is driven from a conventional gas turbine and produces the forward vertical lift. The 3BSM is a swivelling jet pipe capable of redirecting the main engine thrust downward to provide the rear vertical lift. It can rotate through 95 degrees in 2.5 seconds and passes 18,000lbf of thrust. Aircraft roll control is achieved using the Roll Posts mounted in the wings of the aircraft, which provide a further 1,950lbf of thrust each.
