Forgive my ignorance to the aeronautical engineers, I just can not see how the nacell and engine can produce lift Dynamic, esp. Static. In fact all advancements I have seen are to reduce disruption to the wing's lift producing capabilities. I have allways been taught that they are designed with the intent of producing minimal drag in operation and that a windmilling or locked engine esp creates allot of drag. An engine vibe failue is designed to shear the aft mount first creating an AOA to send the motor over the wing.
