You'll have to forgive me for not reading the whole thread before posting.
(I have a migraine, so sue me.)
Anyways, I designed an interplanetary ship awhile back, simply because I felt like it.
Some of the stuff is'nt exactly usable yet, but it will become viable in the next 50 years
at the most, honestly it's more just the Fusion generators more than anything
that date so far forward.
I gave it a name, the Odyssey, so in the explanatory notes (which are from when I first
created it) reference it as such.
The Odyssey is a large Interplanetary civil transport ship.
A. It's main propulsion source are two Dilithium/Tritium fusion rocket engines.
B. The large sphere in the rear of the ship houses the engines and fusion power plants
that provide the power for them and the ship as a whole.
C. The main fuselage of the ship contains many things, namely the fiber optic
communication system, power distribution cables and zero gravity R&D chambers.
D. The main living ring is where the passenger area is.
The ring is comprised of six decks on the inside and is protected by a hull made of Titanium,
lead and carbon nanotubes, with an outer layer of three inches of perfect lattice diamond.
It is spun to provide .7 gravity.
E. The command ring is a smaller ring spun to provide 1.0 gravity. It is the ships
main command center.
F. The impact shield is comprised of a four feet of perfect lattice diamond and five
feet of steel with carbon nanotubes interlaced. It also houses an Electro-Magnetic field
generator that helps by deflecting 70% of material out of the ships way within a two
mile range in front of the ship.
G. The maneuvering engines can turret 190º. They are used to reduce the ships cruise
speed by 30% and to flip the ship around for deceleration.
H. There are four sets of escape shuttle-pod strips, each containing six escape
shuttle-pods that can carry twenty-five individuals each.
I. There are 8 separate weapons clusters, four in the impact shield spaced randomly,
and four on the main living ring spaced equidistantly around the ring.
The ship uses a Super-Computer to provide for the complex calculations required for the
course plotting and acceleration and de-acceleration maneuvers.
The ship can hold a maximum of 100 crew members and 600 passengers.
The ship is armed with Magnetic Acceleration Guns (Railguns), point defense lasers
and cluster missiles.
Not sure it's what you're looking for, but I figure I might as well submit it if not for anything
but possible reference material.
