Some ships have really wierd designs that don't seem to make sense at first. But sometimes I either run across info or think of a reason why a design is as it is, and these reasons are rather neat at times, and so I thought I'd share some here. First, the Oberth.....
Why is it designed like that, with no connecting pylon in the middle for a turbolift?
Answer: I ran across a reference that the ship was originally designed to be able to do a routine saucer seperation so that the top part can fly through atmospheres, and even land. Quite useful for a survey/research vessel. That's why it's so FLAT on the bottom. This is intereting to know.
Next question: The Enterprie-B. Why for pity's sake are the warp engines located RIGHT BEHIND the extra impulse engines? Wouldn't that block the exhaust?
Answer: This is not an official answer, but it was a thought that struck me......What if the matter intakes on the warp engines are meant to PICK UP the impulse exhaust? I mean, why not? You get a high concentration of matter that is being expelled anyways, might as well RECYCLE it. That would mean it would be picking up helium particles as opposed to plain hydrogen, but then the intakes on the Enterprise-B are not red but for some confoudning reason glow BLUE. Does intaking helium, and not hydrogen, make the intakes glow blue? And to use the helium in the warp reaction you might need to break it down into hydrogen again, but even this creates an energetic reaction, which means more energy for the ship in the process. All in all, if this is correct, it seems like an experimental drive/fuel system that was being experimented with on the Enterprise-B.
