Propellers

One of the primary forms of propulsion in From the Depths is propellers, especially for waterborne and underwater vehicles. They only work under water. If you want propulsion underwater than you will want propellers.

Basic Components

All basic propellers use engine power to create propulsion.

• Propeller: Basic small propellor used for propulsion underwater. Comes in square or circular designs, the difference only being appearance. They are a foundational 1x1x1 form of propulsion.
• Huge Propeller: Larger version of the small propeller. Comes in square or circular designs, the difference only being appearance. They are a foundational 3x3x1 form of propulsion. They are directly proportional to the small version in every stat.

These components can be used for a variety of uses and all share the same strenghts and limitations.

• Max speed is 100 m/s.
• Propellers need 8 meters of empty space behind them to work at max efficiency. If something blocks them then they will lose a proportional amount of strength.
• Both large and small propellers only need a 1x1 radius area behind them. This means you can use a large propeller with a small gap to create a larger form of propulsion with smaller weak points.
• Simple to add to a vehicle, providing large amounts of thrust for a reasonable cost.
• Small propellers make great thrusters for pitch, yaw, and roll.
• Large propelloers make great thrusters for forward velocity.

Steam Propellers

Steam propellers are an extension of Steam Engines. They can create massive amounts of underwater thrust, but at increased cost and complexity. For a more detailed explanation of steam propellers, got to the Steam Engines page.
