Abstract
1,042,932. Aerial spraying. RIPPER ROBOTS Ltd. Feb. 18, 1964 [Feb. 21, 1963], No. 7091/63. Heading AID. [Also in Division B2] An aircraft has a spray-bar S suspended on two linear actuators J. J<SP>1</SP> e.g. hydraulic, pneumatic or electrically operated jacks automatically controlled by a summing and amplifying unit 18 to keep the spray-bar substantially parallel to and at a substantially constant height above the ground which is being sprayed. Demand signals indicating the required heights of the aircraft and spray bar are fed into the unit 18, as also are signals from height-aboveground measuring devices 15, 15<SP>1</SP> and 17. The signals are algebraically summed and actuator extension error signals are fed to servo-valves V, V<SP>1</SP> respectively to effect extension or retraction of the actuators until the error signals are both zero. The aircraft may also include means which relays height error to a system which controls the aircraft's vertical movements. When traversing rough ground or ground carrying a standing crop filters may be included in the summing and amplifying networks to eliminate unwanted high frequency components.
