ABSTRACT:
An airborne container for a liquid or other flowable material has bottom doors which are opened to release the material on the ground below the aircraft. To maintain a specified coverage level, a control system which includes a digital controller repeatedly calculates a differential pressure across the doors and varies the position of the doors to maintain a constant material flow rate as the differential pressure varies. The control system closes the doors when a specified volume of material has been spread.
