Voyager's folding wing-and-nacelle warp drive system allows the Notably, when low warp is initiated this same movement doesn't always seem to take place The new 'folding wing' seems to negate this by moving when initiating high warp (or creating a substantial warp field).

After the events of TNG ' Force of Nature' it was proven that high speed warp damages the structure of subspace. The Voyager entry on speaks to the reason for the movable ('variable geometery') warp nacelles. Why can the warp-nacelles be lowered? Why are they not fixed in the position which is best for flying on warp? Maybe they are less exposed in combat-situations? Are they easier to access for reparations if they are lowered? Can the Bussard-collectors work more efficiently if they don't have the saucer-section blocking their ways? Why are they not forged in the favourable position for warp? For some reason it must be better to lower the nacelles when you fly on impulse. The nacelles are not involve in the propulsion of the ship when on impulse.

The answer is simple: 'Because in trek-physics it's better to have them there when going to warp.' My question is more: 'Why are they lowered when dropping to impulse?' So my question is less: 'Why do the nacelles rise when they go to warp?'. And hence it's good (for whatever reason - be it energy efficiency or more speed.) to have them in that position. I'm absolutely fine with the idea, that a certain angle/position of the nacelles is better than others.

Why do voyagers nacelles move
