The flight craft in my Dieselpunk-ish Science Fantasy setting are heavily inspired by the Hovercraft of The Matrix series. I think that those ships have a very interesting look, and they are the first levitating craft that I saw with actual visible engines.
Though unlike the hovercraft from the Matrix which use magnetic-levitation, my craft utilize the Cosmic Aether. However other than that one fantastical quirk the engines utilize similar principles.
My question is from where do I even the ship's excess heat? This is more for my peace of mind, and it isn't likely to be all that important in the story.
I drew inspiration for the managment systems from Mass Effect in particular The Normandy's stealth-systems and a few bits from Atomic Rocket, and one major piece of Unobtainium. Ships circulate coolant, the cycle ends in massive heat wells that are connected to radiators. The Heat wells incorporate a rare and difficult to synthesis mineral(the afore mentioned Unobtainium),this mineral is very heat conductive and has an exotic structure, it partially exists and radiats heat outside three dimensional space. However the mineral doesn't radiate heat at a high enough rate to eliminate the need for external radiators.
So I ask where exactly do I put them on my ships?
