Abstract: This invention provides a mobile aerosol generator which enables the vehicle operator to remotely reposition the droplet launch trajectory during normal operation of the generator and the vehicle. Azimuth and elevation launch directions are controlled separately or simultaneously by the vehicle operator using a remote control box. The repositioning ranges are about 180 degrees in azimuth included angle centered about a preset position, normally the direction of vehicle travel, and from about 60 degrees above to about 15 degrees below the plane of vehicle travel. A turntable like actuator provides azimuth repositioning and a linear actuator coupled to the nozzle provides elevation repositioning. Tubular nozzle support structure also acts as conduit for pressurized air to a two-fluid nozzle. A liquid delivery system provides a controlled amount of liquid to the nozzle where the fluid is sheared into droplets using pressurized air.
