As far as I know, Turbines have yet to be invented? If they had been, I would attach that to the Eclipse Engine. Or be fine with SCTA. It's the creating Turbines which I am avoiding.
Eclipse Engines run off a very basic premises, which can be modified with ease for whatever your are making, as the basic idea is heating and cooling systems and continual flow.
The Eclipse Engine does not have an attached design, but as the invention that Represents Etroan Industrialization, it will sink it's way into everything we do in the future.
Main point is that turbines haven't been created, so I created an engine that can be used for anything steam powered into the future.
Ithil, & the Aiwenor
Ithil is created by Skytear powder in an enclosed(and anchored) foundry. Molten Copper is then added into the mix. This causes Skytear's natural reaction to change, it's density no longer changing when hot or cold, which allows it to be forged normally. Instead, when Ithil is fed with electricity, it's effective density changes, causing it to lift. The more electricity poured in, the greater the lifting force. Not only that, Ithil is highly resistant to change of shape, only being able to be molded when molten, to the point that weight can't actually flatten it's surface tension, which repeats throughout the entire structure.(Though it can crack from cannon fire)
This effectively makes it highly efficient to use in Lighter than Air craft. By setting a bar at the top of the craft and shorter ones at the sides, then feeding them, we can easily lift the aircraft into the sky.
Using this, along with the Steam Turbine on board to generate electricity, we built the Aiwenor, 80 meters long and roughly 16 meters in diameter. Comprised of aluminium paneling in an oval shape, with iron beams for supports and structure, and wood for furniture and rooms, it uses the electricity the turbine produces to move the propellers at the backside of it. Along with fins on the sides for control, it could make a solid 30 knots, and carry a lot of cargo and passengers.
Cannons were installed in the sides meant to fire down, using explosive shells, making them deadly bombardment in a time where planes did not exist. Ithil could theoretically carry tons upon tons of weight so long as enough Ithil was used, and/or enough electricity was supplied to it. Their role in bombardment and scouting from far above typical weapons can be said to have changed the face of warfare. Worst of all, they were very tough to take down even when you managed to hit them due to not using any form of gas for lift.
