I like the lighting and renderer you used. Very cool.

Lets say the scout ship's maneuver drive was damaged, could it make an unpowered landing using its glide characteristic? It is basically a wedge-shaped hull, which means it is a flying wing. Seems the landing gear is not particularly designed for making runway landings.

All depends on its mass (unpowered landings). The lift effect has to overcome it's mass or it drops like a rock. Also it has to have the right reentry angle in order to generate lift.

Trivia the AN-225 is twice the size of an S-type. :D Way to go Antonov :D

Size matters not, unless it can generate lift. And aerodynamics, too. You'll notice that pretty much all lift in an aircraft is provided for by the wings and not the body itself. Since an S-type has no wings...

I just have them crash when that happens, similar to https://youtu.be/UV17B8oq_cE?t=12s

There are ways to generate lift without an actual wing. There were experiments using airflow over a body to form small eddies of air that redirected airflow across the surface of an object. they worked fairly well, but since a wing is very cheap and simple to build the idea is pretty much a parlor trick for aeronautical engineers.

one design was to catch air at teh leading edge of an object and channel it through small tubes, the tubes released the air in a way that formed small eddies, and forced the air up and over the eddies, that fored the air flowing over the surface to take a slightly longer trip around the object on one side...which is what causes lift in a wing.

I'm not saying you could make an S-type fly on aerodynamic lift alone without a lifting hull, or wings..but it'd be a great way to explain how Aerofins could work on a body that has no visible fins for example...just intakes, air channels, and pop up panels/air-brakes built into the hull..might be a good twist to add to an S-type, or Fiery escort as an interesting modification..since both those types have fairly streamlined hulls.

If that happened in a game I was running I would assume the skids would be built to accommodate both vertical landings and landing on runways. Maybe the skids would have small rollers on the bottom. Or maybe they would be a bit like a WWI British tank where there would be tracks all around the skid.

However, if they are landing on rough ground, who knows might go wrong :mrgreen:

Sure, but even those aircraft have wings, and also highly aerodynamic hulls that act as a wing. Scouts use crystal-iron for their hull, not lightweight composites and other techniques to minimize mass. Any craft designed for space travel is going to be optomized for that function. Meaning it needs to stand up to the rigors of spaceflight, micrometeorites, radiation, etc. With anti-gravity mass is no issue for takeoff, so they are going to build it to survive that.

I'm not saying a Type-S couldn't do it, but I think it's overall mass would far exceed the amount of lift it might be able to generate while gliding in. Then again, if Traveller spacecraft are built as tough as the Millenium Falcon, I'd say it doesn't have to worry about the occassional rough landing or forest in the wrong place.

Nice work. I assume you make the models yourself. What do you use, Maya, 3ds Max or something else?

Thanks, that is more of an interesting comment to me than the 'why, what and huh>? of the design.. '

I use Sketchup and lots of Photoshop work usually.. Oh and a render engine, Vray sometimes (a mate has it) and Indigo.
And yes I make these myself.

Very good work. The stuff you have posted here and on your blog really capture the feeling of the CT designs.

I've been trying to get into Blender but that learning curve is pretty steep, even for a modeling program.

yes the blender learning curve is steep, very steep...and slippery :) but the results can be very nice....

as for the models, I would love to know how some of the detail on the aft end turned out so clean and clear, the edges look very sharp, so I am curious as to how that was done.
