Jet Engines

One of the primary forms of propulsion in From the Depths is jet engines, especially for airborne vehicles. The only work above water and lose their effectiveness as altitude increases. If you want your vehicle to go fast then jet engines are your best friend.

Basic Components

All basic jet engine components use engine power to create propulsion.

• Jet Engine : Basic small jet engine used for propulsion. Comes in standard circular or the square flush design, the differences only being appearance. They are a foundational 1x1x1 form of propulsion.
• Huge Jet Engine" Larger version of the small jet engine. Comes in standard circular or the square flush design, the differences only being appearance. They are a foundational 3x3x1 form of propulsion. They are directly proportional in power 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 150 m/s.
• Engines need 10 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 jet engines only need a 1x1 radius area behind them. This means you can use a large engine 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 jet engines make great thrusters for pitch, yaw, and roll.
• Large engines make great thrusters for forward velocity and for hovering.

Custom Jets

While the basic jet engine parts are a simple and effective means of propulsion, custom jet engines (CJE) have potential to be more powerful and/or more efficient if built properly. This comes at the cost of much greater complexity and design requirements. Additionally, custom jets use materials to create propulsion instead of engine power like the basic jet engine components.

Components

All CJE components come in small and regular sizes, which function proportionally similarly to the basic small and large engines.

• Intake: Feeds air into the CJE. It must be above water to work. Ducts can be used to intake air from different angles or even different locations on the vehicle, allowing you to build CJEs more inside your vehicle than you can with the basic jet engines.
  • Intake Add-on: Placed on the side of the intake to increase the amount of air available to the engine. Provides slight thrust increase without adding material usage.
• Compressor: Compresses air from the intake, increasing thrust without increasing resource usage.
  • Extra Compressor: Can be added to the side of compressor segments to increase their performance.
• Jet Generator: Redirects thrust from the CJE to generate engine power or recharge batteries. Has no effect on CJE performance.
• Jet Controller: The primary component of a jet engine. You cannot build a CJE without this central part.
• Combuster: Burns materials and oxygen together, increasing thrust and material use.
  • Injector: Added to the side of a combuster to drastically increase thrust output, at the cost of increased material usage.
  • Extra Combuster: Added to the side of a combuster to increase output. Cheaper and more efficient than an injector, but not as powerful.
• Exhaust Connector: Links combusters to exhausts. Allows for exhaust venting on CJEs.
• Corner Exhaust Connector: Like the Exhaust Connector, but able to be placed offset from the main body of the CJE.
