Abstract

An aerial firefighting system has a foam production unit attached to an aircraft. The foam production unit has a single unit variable block high expansion foam generator; a light weight bladder tank system for collection and storage of water; a light weight bladder tank system for storage of a foaming agent; a telemetry unit for adjusting air flow, foam agent proportioning, and water pressure; and tubing for foam stream straightening. The foam production unit also has a fan capable of delivering at least 75,000 cubic feet per minute of air. The incorporation of a high-CFM fan increases foam production capability more than tenfold over existing aerial firefighting systems. The volume of firefighting foam produced is in excess of 50,000 cubic feet of foam per minute.
