Where's my money?So now for the 64 dollar question?? (that does date us, doesn't it?) when the F-35 Bravo is all cleaned up and transitioned to forward thrust, lift fan door down and locked, does that lift fan continue to spin at a high rpm, or is it taken off line, only to spin up as the forward lift fan is "unlatched"...
The lift can is mated to the turbine by a clutch system. When in fixed wing flight that clutch disengage so the fan slows down the doors close and the is no longer a factor.
As to the doors open the upper door on the lift fan as can be seen in the image I just added would act as a Air break
