Abstract
Water is mixed with fire suppressant polymer in a mixer absent a power source. The mixer receives water through a water inlet with water exhibiting high velocity and associated hydrodynamic force. Such velocity is achieved by locating the water inlet connected to a float or other part of an aircraft so that when the aircraft flies over water with the float dipping into the water, water is driven through the opening and into the water inlet of the mixer. A polymer inlet passes into the mixer. A bend is located downstream of the water inlet and the polymer inlet. The bend exhibits sufficient resistance to fluid flow direction therethrough that the polymer is sheared and thoroughly mixed and activated with the water. A colorant inlet is optionally provided within the mixer and the water and polymer mixture is then discharged into a tank for later utilization at a firefighting location.
