Fireboat Jet Reaction, Thrust and Stability Lab Blender 5.2

A harbour fireboat and an offshore fire-fighting ship put water on a burning warehouse. The jets push the vessel back and heel it; the thrusters and the hull stability have to cope. Drag to orbit, wheel or pinch to zoom, tap the warehouse or sea to aim every monitor there.

Presets

Vessel, pumps and monitors

Pattern Aim at

Auto-aim (tracks the target as the vessel moves)

Station keeping and weather

Thrusters hold station Feed-forward of jet and wind force

The pumps and the thrusters share the engines, so firing more water leaves less power for holding position.

Stability and loading

Pump, jet and graphs

Experiment: how far, and what thruster power?

Question: for this vessel, how far can the jet reach with and without air drag, and how much thruster force and power does it take to hold the vessel against the reaction at five pump speeds? The sweep runs the full station-keeping simulation for 120 s per speed, and the reach scan integrates the jet for every elevation from 5 to 80 degrees. Results are compared with the closed forms.

Press the button. The selected monitors, nozzle, pattern, loading and tank are used; calm sea, no wind.
