Why do you need warp power?

Question. In STiD, Enterprise is falling to her death. Scotty says the warp core is out of alignment and that the ship is dead. Kirk fixes the core and Sulu arrests the big E by... Wait for it ... Firing thrusters???

Why does Enterprise need warp power to fire thrusters? The most you need is wiring, some control circuits, the thrusters themselves, and a bit of aux power to run the whole thing, which they early had... The lights were on.

In ST09, Sulu abandons Warp AND impulse and lifts the ship using thrusters alone.

Re: Why do you need warp power?

There's a difference between the warp engines and the warp reactor itself.

Aux power was gone for whatever reason when they were going down, i'd venture a guess that one of the million hits to the ship probably knocked the sprockets off the auxiliary reactor.

So all you'd have left is the warp core to power the ship, also, we did see (at least i'm pretty sure we did) in one of the TOS episodes that the Enterprise has a hard time maintaining orbit without main power.

Re: Why do you need warp power?

The ship was already drifting toward Earth, and both the main power, and auxiliary power were gone. There was nothing that could give them the force they needed to stop their momentum. Once they got power back online, Sulu fired every thruster they had (there were a shitload... that's a technical term), and they began to rise back up into the air. Once full power came back, they were able to use warp/impulse power to move back into orbit.

Re: Why do you need warp power?

According to other Treks, the warp core powers everything aboard the starship. This is based partially on aircraft in the real world which have to electricity unless the engine is active. Indeed, practically everything had shut down on the
Enterprise, the lights even the artificial gravity which usually always stays active even when nothing else is. The warp core was needed simply to power the ship.

Re: Why do you need warp power?

When the warp core came on line you can see the nacelles start to spin up - my guess is that part of having the nacelles powered up is that part of their function is to reduce the ship's mass, because there's really no other way those little thrusters would be able to arrest Enterprise's fall.

Excellent. Someone's paying attention to the Physics of Star Trek.

Re: Why do you need warp power?

Yeah, thrusters weren't the only thing firing, otherwise Enterprise would have started falling again as soon as they shut off, immediately after their rise above the clouds.

I attributed the loss of gravity to the loss of warp, impulse, aux, AND batteries. While warp power is primary, the other sources would kick in and provide partial power to systems when the core is off line. We've also seen this in several eps and movies. Warp core is off line but aux and impulse are used for maneuvers and operations, just no warp speed.

With gravity out and Enterprise in free fall, both warp and impulse are clearly out. But the lights in the ship are on. This power is enough to fire thrusters, so he real question is whether the shellac of thrusters could arrest E's fall, or if warp is required.

The lights in the ship are on, yes, but batteries do not equal thrusting power. It was only when power was restored that they had thruster capability. Seconds later, the warp engines begin starting up, and the ship is able to lift itself out of freefall.

Re: Why do you need warp power?

Which reminds me; I have never really thought about how much power starships had to have. Even in the Original Series, TNG, DS9, etc., at no time did I ever feel the power of these ships, even in the movies, until ST09, and STiD really hit it home. The Enterprise generates massive amounts of power. From warp speed, or pushing through an atmosphere, to firing batteries of weapons in the blink of an eye, this ship is pure, raw, barely controlled power, and I love it. For me, the last two movies have made the redesigned Enterprise my favorite ship.

Aha. The aft nacelle must be where auxiliary power comes from.

Batteries don't need thrusting power. The chemical reaction of the thrusters themselves do that. All you need power for is to turn them ON, and then some computational overhead to coordinate them so you don't end up doing donuts all over the sky.

It depends upon what kind of thrusters are being used. You assume chemical thrusters, but perhaps the Enterprise doesn't use chemical thrusters. Even if they are chemical thrusters, how much thrust will they have? They're likely RCS type thrusters for short bursts of navigational course correction when not in warp.
