Hello, This has been nagging me for years. On the Voyager, why did the nacelles change position to go to warp? From a design standpoint it just does not make sense to me. Why not leave them in the correct position all the time? I know the real life answer is the producers wanted "something cool that moved" on the ship. I just wanted your idea on an "in Universe" reason for it. The best idea I came up with would be "variable geometry", i.e. they would change angle of attack to best suit the warp dynamics for the speed they were going. (much like the wings of an F-14 or F-111) Unfortunately, in the show, they were not portrayed this way. They went straight from stowed position to warp position. Thanks in advance for your time!
