A fire fighting system uses a bucket suspended from a helicopter to deposit fire retardant onto a fire from an opening in the bottom of the bucket. The bucket has a predetermined configuration and a valve for controlling the area of an opening through which the retardant is deposited when the bucket is suspended from the helicopter. A suitable mechanism, such as an electrically driven valve actuator, varies the area of the opening to deposit the retardant at a volume flow rate as a desired function of time while the helicopter flies along a drop line. Th...
[ What is claimed is:] [1.] A bucket for depositing a flowable material, the bucket comprising:means for attaching the bucket to an aircraft;an opening in the bucket for discharging the material; anda flow controller for varying the characteristics of the flow through said opening to discharge the material at a volume flow rate as a desired function of time while the aircraft flies over a drop zone, wherein said flow controller varies the characteristics of the flow through said opening as a set function of time determined prior to initiation of discharg...
