Forest Fire All-Terrain Vehicle Lab Blender 5.2

A 6x6 / tracked forest fire vehicle with a 4,000 L tank, roof water monitor and a firebreak blade. Learn traction (tan θ = μ), soft-soil sinkage, rollover from the centre of gravity, the pump and jet, and how a ground fire spreads. Drive with WASD / arrows or the joystick; Space = water, B = blade, R = refill, X = brake, V = view. Tap the ground to aim the monitor. Unmanned training scene; the fire is a stylised model.

Experiment: how steep is safe, full tank vs empty?

Question: on which slope does the vehicle slide, roll over or lose traction, and how does the water in the tank change it? The instant sweep runs a time-domain simulation for 100 %, 50 % and 0 % water and compares it with the formulas. The 3D test tilts a platform under the vehicle in front of you.

Press a button. The current running gear, ground, tyre pressure and baffles are used.

Experiment: how wide must a firebreak be?

Question: does a plough strip of 3, 6, 9 or 12 m stop a fire, and how does the wind change that? This runs the fire model headless many times with the wind and fuel dryness set in "Fire and weather".
