Originally, the lift-fan door was scheduled to open to 65deg below 120kt in semi-jet-borne flight, and to 35deg above that airspeed. Now the door will stay fully open to 165kt to reduce the loads on the auxiliary-inlet doors. Lockheed's JD McFarlan, who is now in change of the test program, says the change does not significantly impact short take-off performance.
Yeah right !!
