Iron Biplane Engines
by BlatFan
Iron Biplane Engines adds five engine tiers, from Copper to Nlium, for the biplanes of Immersive Aircraft on Forge.
What it does
Each engine tier raises engine power and changes fuel use, so higher tiers fly with more thrust and burn more fuel per trip. The Copper Engine gives +20 engine power and needs +10 fuel, the Iron Engine gives +40 and +20, and the Gold Engine gives +60 and +30. The Diamond Engine reaches +80 power with +40 fuel, the Netherite Engine +100 with +50 fuel, and the Blatium Engine +150 with +50 fuel. The top tier, the Nlium Engine, adds +200 engine power.
Immersive Aircraft is required, so it must be installed alongside this mod. Blatium is an optional dependency, and the author notes that the mod is meant to support it. The mod is published for Forge only, for Minecraft 1.20.1, and it runs on client and server, so both the server and every player need it. The code is open source under the MIT License.
Key features
Five engine tiers
Copper, Iron, Gold, Diamond and Netherite engines are added as craftable upgrades for biplanes.
Blatium Engine
A Blatium tier sits above Netherite, with +150 engine power and +50 fuel requirement.
Nlium Engine
The highest tier, the Nlium Engine, adds +200 engine power to the aircraft that carries it.
Power against fuel
Every tier pairs more engine power with a higher fuel requirement, so stronger engines cost more fuel to run.

Use cases
Upgrading a biplane
Players who fly biplanes can move from the Copper Engine up to the Nlium Engine as their materials allow.
Balancing fuel use
Server owners who want flight to cost more can rely on the fuel requirement that rises with each tier.
Who it’s for: Players who already use Immersive Aircraft and want stronger biplane engines, and server owners who run Immersive Aircraft with the mod installed on both sides.
