What are the observed different types of Warp Drives?

Well it looks like neither one of us guessed correctly :). In "Eye of the Beholder" we see the E-D's plasma venting system engage for the starboard nacelle and the vent is on the bottom of the nacelle near the front.
Maybe that was an Art Department screw up?

So what are the blue energy grills for? Your guess is as good as any
A permeable layer of translucent material where Sub-Space fields can go through while keeping general Space Particulate out of the Warp Coil Assembly.

I put more weight in what's on screen so I'm thinking the blueprint is inaccurate.

Is there any episode that stated that warp fields can't pass through the hull? We've seen that the E-D has pushed a warp field into a small moon so it doesn't seem that there is a rule that it needs something permeable.

I've seen interviews on TrekYards on how the Art Department screw things up behind the scenes compared to the original designers layout / intent. So I'm not 100% trusting of everything is accurate on screen.

Not to my knowledge, then Warp Field grilles really are "Photonic Spill Ports" on top of keeping particulate matter out of the Warp Coils. According to some stuff that I've read, for Warp Engines to work at higher levels, it needs to evacuate photons from the cavity of the Warp Coils ASAP, ergo the name "Photonic Spill Ports". Ergo the higher Warp speeds they go, the greater the glow should become.

Sure, we have lots of well known instances where the production doesn't match up to the original designers layout/intent. The TMP Enterprise is one of those examples. You can imagine a screen accurate Enterprise or the one Andrew Probert intended or some mashup of the two or something different entirely :) At the the end of the day, you decide where your head canon is going to be. I put my head canon into what's shown on screen and if we differ that's cool.

But, who is Mont Johnjulio? You reference his E-D blueprint work for the plasma vent port but I thought Andrew Probert was the original designer? Why should Johnjulio's work be considered an original designer intent or am I missing a detail here?

He's not a original designer, just the guy who did the Blue Prints for that set of Orthographic Views of the Enterprise D and labelled what all the things on the Enterprise D is.

Ah, well in that case, I'm going with the episode's depicted location. YMMV :)
 
Aridas Sophia has a nice concept called the Advanced Circumferential Engine—the ACE nacelle that points toward TNG designs,
 
I was looking at Cardassian starships recently, and it hit me that all of them (Galor, "thicc Galor," Hideki, and the freighter) have that forked design element. It made me wonder if the fork is a feature of their version of warp drive...perhaps some sort of "tuning fork" to project and control the warp field.

On combat starships (Galor, Hideki) the "tuning fork" is mounted at the stern; maybe for maximum maneuverability "within subspace" or for safety concerns? Meanwhile, the freighter has it mounted at the fore since it's hauling heavy loads...I've read that having the engine pull instead of push the mass of the ship would make for a more stable space vehicle (this theory was used when creating the ISV Venture Star in James Cameron's Avatar).

The only outliers are the transport Bok'nor (a reuse of the "Merchantman" model) and the dreadnought missile from Voyager...
*I like to think "Merchantman" type ships in the Alpha/Beta Quadrants are a common design churned out by many cultures on the cheap; maybe the Cardassians purchased or copied the design from another power.
*perhaps the dreadnought carries its "tuning fork" internally?

I thought the "tuning fork" was something else.

Do you have diagrams that indicate the parts on the vessel?

Nope! I have nothing to support this beyond my own musings. :cardie:

I'm aware Sternbach intended it to be a massive disruptor (like on the Klingon Vor'cha), but to my knowledge we never see this feature firing during any appearance of a Galor, Keldon, or Cardie freighter. He also wanted the little pyramids on the wings to be phaser emitters (a very cool idea), but the effects guys always showed the Galor firing from an area he thought of as the navigational deflector.

*I'm not a fan of the "tuning fork" being a weapon. Why is it at the stern? I guess it would be good for surprising pursuers; and if you're charging the enemy in combat, the ship could pivot (while maintaining speed + heading) so the stern is pointed at the enemy...but I just don't dig the idea.
*If it's a powerful weapon, why is the Cardassian freighter said to be so weak, and almost incapable of damaging a Klingon Bird-of-Prey?

I don't mind the "Tuning Fork" aspect as being a weapon:

I actually like the design as a concept for big capacity particle beam weapons that can compress into a smaller form factor.

The front could be better shielded? so that you charge past incoming fire and shoot them when your aft is facing the enemy?
I have no idea why it's mounted on the back.

You got to remember that freighters aren't armed with the latest greatest weapons on most StarShips.

It only needs to ward off "Pirates" and destroy asteroids.

Indeed, they mention how ineffective the freighter's weapons are in the episode "Return to Grace." Yet the ship mounts the "tuning fork" as a prominent, forward facing feature. Is the fork a gigantic but ineffective phaser/disruptor on the freighter, then?

The "tuning fork" shape being part of all observed Cardassian starship hulls (warships and non-combat vessels) suggests to me that it's a common feature of their spaceflight technology...but again, there's no onscreen evidence to support this (same as the disruptor theory). :shrug:

*If the Cardassians designed the Galor class to reflect the shape of their government's emblem (which would be hilarious), the "fork" could a primarily ornamental feature. :cardie:
 
There's the "coaxial warp drive" from the alien test shuttle in Vis-a-Vis. allowing for instantaneous jumps over vast distances.

But that one might be from a very different family of propulsion system, only sharing "warp drive" in its name because it warps space to some extent.
