Engine Units

Engine units are elements that allow constructs to move through a variety of propulsion methods. All engines require fuel to operate, with space and atmosphere engines requiring different types of fuel, and therefore they will not operate unless connected to a fuel tank that contains the appropriate fuel type.
 * Hover engines allow constructs to hover in planetary atmospheres, but beyond a certain altitude their efficiency decreases rapidly.
 * Atmospheric Engines allow constructs to fly through a planet's atmosphere, but they do not function in space.
 * Space engines allow constructs to fly in space, but they do not function in a planet's atmosphere.
 * Rocket engines operate in both space and atmosphere, but less efficiently than either space or atmosphere engines.
 * Warp Drives allow constructs to travel and supra-light speeds, and are typically used for travel between planets and solar systems (see Interstellar Travel). These engines only function in space.
 * Adjustors are a special type of engine that applies limited directional thrust. These engines are primarily placed at strategic locations on a construct to increase turning rate and maneuverability.
 * Retro engines generate artificial friction to stabilize the ship . these engines only work in space.

The fuel requirements for other types of engines are not known at this time.

Atmospheric Engines
N / L/h: the amount of thrust provided by the engines divided by the amount of fuel they burn per hour

N / t: the amount of thrust provided by the engines divided by the engines' weight

Space Engines
N / L/h: the amount of thrust provided by the engines divided by the amount of fuel they burn per hour

N / t: the amount of thrust provided by the engines divided by the engines' weight
