The turbofan is a mid-game, aviation grade petroleum fueled generator.
Description
The turbofan, in-game, is a static-fire version of a conventional turbofan jet engine, stripped of its cowling. It resembles the RR Trent-900, albeit with a smaller fan housing, a broader combustion chamber, and a stubbier exhaust. It also features what appear to be afterburners (the 8 radially mounted brown chambers) at the back of the assembly.
Production
The Turbofan is crafted in the Assembly Machine with the following items:
Statistics
The turbofan generates a varying amount of power. The power production is listed in the table below. The engine can only use aviation grade fuel, which only (at the time this page was written) consists of kerosene and jet fuel.
| Aft. upgrade | Kerosene | Jet fuel |
|---|---|---|
| 0 | 77kHE/s | 192kHE/s |
| 1 | 154kHE/s | 384kHE/s |
| 2 | 231kHE/s | 576kHE/s |
| 3 | 308kHE/s | 768kHE/s |
- It is preferable to use jet fuel instead of kerosene, as the power output is nearly doubled
- Note that, despite kerosene being an inefficient jet fuel in real life, the consumption is universal.
- The engine cannot use avgas (leaded gasoline) as it is not a turboprop.
- Note that, despite kerosene being an inefficient jet fuel in real life, the consumption is universal.
Usage
The turbofan can be primarily used for power generation, while it is not as powerful as a ZIRNOX reactor without afterburner upgrades, the turbofan can dwarf it with ease using a tier 3 afterburner upgrade in combination with jet fuel. The turbofan can be a solid choice for power production before fusion, or RBMK reactors.
It may also be used, to a lesser extent, as a tool of area denial. While the engine is online, it has the ability to push creatures back relative to the exhaust, the distance, speed and flame damage is affected by afterburner upgrades. The intake can also draw in creatures and kill them instantly upon contact with the fan blades. Furthermore, the loud noise produced while it's running makes it virtually impossible to hear anything else in its proximity.
The engine also has a built-in blood collector; upon contact with aforementioned fan blades when the engine is online, a creature will get killed and add 1,000 mB of blood to the collector, capping out at 24,000 mB. Blood is mainly used for heat exchange.
- The size of a creature does not affect the amount of blood generated.
- Note that, no matter the size, a creature will never total a turbofan. The engine will operate until it is exhausted of fuel.
Trivia
- The turbofan, despite common misconception, is in fact, a turbofan. While it may appear as if the engine cannot fit a turbine inside, it does in fact have one, although most probably downsized as to not make the machine cumbersome to use.
- The turbofan features a bypass duct leading nowhere. This is explained by the fact that the engine has no cowling and is bolted to the ground, and bypass is therefore useless.
- The "pointy part of the nozzle" (or compressor assembly, depending on the engine) appears stubbier and can be mistaken to be missing. The aforementioned part had been squished to make the assembly fit in a 3x3x7 space.
- A turboshaft does not have this, instead, it is fitted with a rotating power shaft utilized outside of the engine assembly (instead of a turbine). Several turbine shafts are used to make the turbofan, but they are used to turn a generator inside of the assembly instead of helicopter blades.
- The combustion chambers appear to be more tightly packed. While this may be a blunder, it (alongside bypass air not being utilized) could explain the rather low propulsion generated by the engine.
- Blocking the air intake does not impede engine performance. This is done for gameplay reasons.
- The jet fuel used in the turbofan is most likely Jet A-1, as it is kerosene (which would be A0 in this context) with an additive.
- The only allowed additive in real life would be a form of (essentially) antifreeze, not reformate.
