This is my (very) humble attempt to make a contribution to an incredible simulation (thank you Martins!), and a great community, that really makes it come alive! "OMG it's full of addons", and of course the general atmosphere and humour!
I wanted something simple as a POC, and due to the general lack of SSTOs (for LaunchMFD!) I decided for the Kankoh Maru (I think I saw one as a very early WIP but AFAIK there isn't one in Orbiter yet). It took a long time but I finally got it this far:
Function: Manned Re-usable rocket
Country of origin: Japan
Size
Height: 22m (72.00ft)- (23.5m)
Diameter: 18m (59ft)
Mass: 550t (1,210,000lb)
Dry Mass: 50t
Thrust:
LE-9B-3 Boosters - sea level : 162,959 lbs, 725,000 N
LE-9S-3 Sustainers - vacuum : 193,527 lbs, 861,000 N
Stages: 1
Passengers: 50
Capacity Payload to LEO: 4t (8,800lb)
Launch history: Status Proposed
Japanese manned spacecraft. Study 1995. Kawasaki design for single stage to orbit reusable booster. Would carry 50 passengers to orbiting hotels or fast intercontinental flights.
The Transportation Research Committee is led by Kawasaki Heavy Industries, and members of the committee include staff from Mitsubishi Heavy Industries, Fuji Heavy Industries, Ishikawajima Harima Heavy Industries, Nissan Motor Company, All Nippon Airways, Teisan, Japan Aircraft Development Corporation and the Institute of Space and Astronautical Science. The Committee held 9 meetings during 1993 and 1994, and produced the conceptual design of the " Kankoh-maru" VTOL SSTO vehicle.
Using existing and near-term technology the Kawasaki S-1 is an aluminum and composite, vertical-takeoff, vertical landing, base-first entry, single-stage to orbit spacecraft. Each vehicle is designed to fly 300 times per year, and to have a 10 year life.
Thrust for takeoff is supplied by 12 Mitsubishi LE-9 engines, burning liquid oxygen and liquid hydrogen. 4 of the engines are LE-9B-3 "booster" engines, optimized for low altitude operation. The other 8 engines are LE-9S-3 "Sustainer" engines, optimized for vacuum operation. The vehicle afterbody is designed to use the vehicle exhaust and the atmosphere as an "aerospike" nozzle to increase efficiency at all altitudes.

It's SC3 (for now (for ever?))
Mesh, animations, visuals, basic ini are done
Keys:
G: gear
K: dock cover
SHIFT+NUMPD 1: sustainer engine covers
SHIFT+NUMPD 2: booster engine covers
It should have two engine modes but this is not practical in SC3 (an invisible payload as an orbital version etc..., maybe later)
It flies pretty much like (I think) it should (clumsy, slow), but I had to tweak it a lot! I don't know if the original stats are porked or if I ballsed up somewhere? and I've tried to figure out the aerodynamics!?! but to no avail; reentry is... sub optimal. This is where I could really use some HELP! and/or tips. I would like it to be as realistic as possible so I'm a little surprised that the original stats (spec. engine) are so far off? If someone could check this I'd very much appreciate it, I've put comments in the ini.
Things to do:
documentation
aerodynamics/ ini - see above
re-texture- I might redo the main tex- it was originally just a quicky (windows are very ugly!)
credits- I'm pretty sure I've only used generic textures (and my own), if anybody recognizes anything else please tell me, Ill give credit or change it.
anything I forgot
Known bugs:
Animations don't close flush when saved in the open position- comes from cheating with the SC3 code
Weird twist jump when landed?- have seen this before, maybe something to do with left/right mesh coords?
constructive criticism/comments and help are welcome
thank you in anticipation of your support
