Fire fighting bucket suspendable from aircraft

摘要

Firefighting bucket ( 11 ) suspended from an aircraft by lines ( 15 ), has open top ( 12 A) and a valve at base ( 13 ). The valve is attachable to the aircraft by remotely actuatable line ( 16 ) and independent movement of lines ( 15 - 16 ) may utilise the weight of the water to facilitate opening and closing of the valve. Dynamic sensing of a bucket attribute, e.g. weight, enables bucket ( 11 ) to be filled or discharged by a pre-determined volume by the pilot. Chemical fire retardant may be added by entraining it with water discharging from the valve.
