🌊 Hydrodynamic Drag & Momentum
Scooping water at 70+ knots generates immense drag force proportional to probe depth and square of velocity. Collecting 500+ liters per second demands full power from twin Pratt & Whitney PW123AF turboprops (3,780 shp each) to avoid severe decelerative stall.
⚖️ Dynamic Weight & Center of Gravity
In under 12 seconds, 6,000 kg of water surges into four hull tanks. As mass increases from 18,100 kg empty payload to 24,100 kg full capacity, the aircraft's center of gravity shifts forward, requiring precise elevator trim adjustments to maintain hydrodynamic lift off the water.
🔥 Wildfire Suppression Drop
Once filled, the CL-415 rotates out of the lake surface, climbs over terrain obstacles, and executes a low-altitude target salvo drop. Door release geometry and entry airspeed determine drop pattern density and fire retardant coverage area.
