Abstract

A foam delivery chute to improve the aerial firefighting process of dropping fire suppressant foam onto fires. The chute is made up of fire-resistant material arranged in a Kresling pattern and designed to provide a guide for the fire suppressant foam. This results in much more accurate delivery of foam, thus making the entire process much more efficient and accurate. The chute is extended or retracted by a mechanical shaft system and is operated by the pilot of the aerial vehicle.
