Excelsior nacelle nomenclature

Didn't the "LN" designation come from the idea that motion picture era ships had a "linear warp drive"? What did the "PB" come from?
 
I'm a bit dissatisfied with the idea that so many visually distinct TNG era nacelles would all have the LF designation.

You can blame me for that one, as well.

I believe LN was both meant to stand for "linear drive" and either first appeared in Starship Design or the Ships of the Star Fleet: Cruisers book. I believe they also noted what the earlier "PB" series stood for, but alas those books are all in storage so I cannot reference them.

I created the LF designation to stand for "linear flat" - the warp coils were linear like on the TMP "LN" series, but lay flat in the TNG nacelles. Mind you, when I came up with it, we'd only seen the GCS-style nacelle. So when the Sovereign and Nova came out with that new nacelle design, I'd already backed myself into a corner...
 
Edit: Lol, once again I post without changing pages.

LF could be "linear fast", maybe? It'd be designator for warp drives built post warp re-scaling.

Me again.

Do we have an LN- designator for the Enterprise-B style nacelles with the external blue bussards?

Yes, this is a project of Jackill-like proportions!

Excelsior (Uprated)
ADSB: K27 (debatable, it also mentions that it's the Transwarp version)
Jackill: SW104/2-12RU

Ambassador
ADSB: LF-10

Damn. Nothing to fit with the LN-series, eh?
Guess I get to make something up! :)

Thanks, Vance.
 
I couldn't find much. After Generations there were a lot of tech-manual-like stuff coming out from the fandom, FASA was gone, and the new official material focused on technobabble, not nomenclature. :S
 
I'm not sure how exactly PB relates to it, but the PB series Warp Drives were described as "Circumfrential" (to contrast the LN series as Linear). There's also notes in some of the 'fleet' sections of SOTSF1 about some scouts being equipped with "Advanced Circumfrential Engines (ACE)", which for some reason I associated with TNG type Nacelles with the red glowing Bussard Collectors making a reappearance.

I can crossreference the class names described as having ACE from SOTSF1 with the schematics on shipschematics.net tomorrow if anyone's interested.
 
:confused: Where do people pull these designations and why do they matter?

In any case, I still maintain that Exelsior transwarp was not a failure, but a success and basis for TNG era engines.
 
Indeed. Exclesior's transwarp drive is in the perfect spot in the timeline to act as the impetus for the warp scale retooling.
 
<Nods in a vaguely avuncularly supportive fashion, pats Jitty on the buttocks>

Also, I like this fan idea of "ACE" as the basis for the TNG engines. What does "circumferential" mean? The TNG Tech Manual would have us believe that each of the warp coils of the E-D gets injected with its own warp plasma, yet the visuals show a single stream going through the middle, at least on idle mode. So perhaps there's also a stream along the circumference of each coil doughnut at drive mode, while "linear" engines only have the center stream going through all the doughnuts?
