Abstract
An aerial spray system can be attached to the undersurface of a helicopter for spraying ground level targets while the helicopter is hovering or in level flight. A television camera can be located in near proximity to the spray nozzles for electronically delivering a picture of the ground level condition to a television monitor in the helicopter, such that the technician is better enabled to aim the spray nozzles or target a specific ground level area. The aerial system can be used for riot control, or crop spraying, or forest fire containment.
Claims11
A system for spraying liquid solutions from the undersurface of a helicopter downwardly onto ground level targets, comprising a liquid storage tank means;
- downwardly-directed spray nozzle means;
- a piping system connecting said liquid storage tank means to said spray nozzle means;
- a television camera sighted downwardly onto the nozzle target area;
- and a television monitor in the helicopter adapted to display the picture taken by the camera;
- said liquid storage tank means comprising a first water tank, a second tank containing a liquid tear gas solution, and a third tank containing a liquid dye;
- said piping system comprising a first mixing means for mixing water from the first tank with tear gas solution from the second tank to produce a dilute tear gas solution, a second mixing means for mixing tear gas solution from the second tank with liquid dye from the third tank to produce a colored tear gas solution, a first pump for pumping water from the water tank directly to the spray nozzle means, and a second pump for pumping tear gas solution and colored tear gas solution to said spray nozzle means.
A system for spraying liquid solutions from the undersurface of a helicopter downwardly onto ground level targets, comprising a liquid storage tank means;
- downwardly-directed spray nozzle means;
- a piping system connecting said liquid storage tank means to said spray nozzle means;
- a television camera sighted downwardly onto the nozzle target area;
- and a television monitor in the helicopter adapted to display the picture taken by said camera;
- said liquid storage tank means comprising a first water tank, and a second tank containing a second liquid solution;
- said water tank having a bottom discharge port means (60) for rapid gravitational discharge of the water content out of said water tank, and a motor-operated valve (62) for opening said discharge port means.
A system for spraying liquid solutions from the undersurface of a helicopter downwardly onto ground level targets, comprising a liquid storage tank means;
- downwardly-directed spray nozzle means;
- a piping system connecting said liquid storage tank means to said spray nozzle means;
- a television camera sighted downwardly onto the nozzle target area;
- and a television monitor in the helicopter adapted to display the picture taken by the camera;
- said spray nozzle means comprising a central bank of nozzles, a left hand bank of nozzles, and a right hand bank of nozzles;
- said liquid storage tank means comprising a first tank containing a liquid tear gas solution, and a second tank containing a liquid dye;
- said piping system comprising a mixing means for mixing liquid tear gas solution from said first tank with liquid dye from said second tank to produce a liquid mixture, a pump for pumping said liquid mixture and said tear gas solution from said first tank to said spray nozzle means, a first solenoid valve controlling liquid flow to the left hand bank of nozzles, and a second solenoid valve controlling liquid flow to the right hand bank of nozzles.
