Aerodynamics4MC

Now compatible with Create: Aeronaustics

📦 What to Download

Core – The physics simulation. Required on every server and in single‑player.

Create: Aeronautics Compat – Want true flight physics? Angle of attack, lift/drag curves (Cl/Cd), and real aerodynamics for your aircraft? Then grab aerodynamics4mc-compat-create-aeronautics-*.jar. It’s the compatibility layer that connects the wind simulation to Create: Aeronautics.

Content Add‑on – Anemometers, sailboats, weather maps, wind vanes… download aerodynamics4mc-content-*.jar. This is the official content pack that lets you see and interact with the wind.

🔬 How It Works

A multi‑scale, server‑authoritative wind field that streams to the client for visual effects — no gimmicks, just physics.

Layer Grid Description 🌍 WorldDriver event‑driven Cyclones, convective clusters, tornado genesis, Rossby waves — large‑scale atmospheric phenomena 🗺️ L0 41×41 (global) Pressure field, geostrophic wind, terrain drag, roughness length ⛰️ L1 33×33×8 (local) Topographic effects, boundary‑layer shear, gap winds, building wakes 💨 L2 (client‑only)(disabled by default) 32³ Sub‑grid turbulence via Lattice‑Boltzmann (LBM) + Smagorinsky model. Drives particles (smoke, leaves, flames) with realistic vortex dynamics

L0 & L1 → calculated on the server, deterministic for everyone. L2 → purely visual, client‑side, required on demand by other mods. Zero network overhead, no gameplay impact.

✈️ Real Flight Physics — Create: Aeronautics Compat

The aerodynamics4mc-compat-create-aeronautics-*.jar replaces arcade-style flight with real aerodynamics. Your aircraft now responds to the live wind field, not just button inputs.

Real wing shapes – NACA 0012 (symmetrical, aerobatic), NACA 2412 (cambered, high lift), and flat plates are built in. Each has its own personality.

Angle of Attack (AoA) – The angle between your wing and the actual wind. Too little → no lift. Too much → stall and sudden drop. You must manage it constantly.

Lift & drag from real data – Cl (lift coefficient) and Cd (drag coefficient) are looked up from real NACA curves based on your current AoA and wing type. This determines exactly how hard the wind lifts and pushes your plane.

Stall dynamics – Exceed the critical AoA and lift collapses. The wind won't forgive bad piloting.

In short: the wind isn't decoration anymore. It lifts your wings, drags you back, and punishes steep angles. You fly in the wind, not through it.

Just install the compat jar on both server and client — no extra setup needed.

❓ Quick Answers

🧩 For Modders & Developers

Aerodynamics4MC exposes a clean API so your own mods can react to realistic wind.
Source code and integration examples live at the Core Repository.

// Example: query the wind vector at any position WindField field = AerodynamicsAPI.getWindField(level); Vector3 wind = field.getWindAt(pos);
