ABSTRACT:
A system for automatically filling and launching balloons which may be used, for example, for cloud seeding. The system includes a balloon launching station frame, a nozzle mounted on the frame onto which the narrow end of a balloon can be attached so that gas can flow through the nozzle into the balloon, a conduit coupled to a source of gas and to the nozzle for delivering gas through the nozzle into the balloon, gas flow control apparatus responsive to first signals for controlling the flow of gas through the conduit, and a release mechanism responsive to second signals for disengaging the balloon from the nozzle to thereby release the balloon to the atmosphere. For launching a series of balloons, the system may include a plurality of nozzles, conduits, gas flow control mechanisms, and release mechanisms arranged so that after one balloon is filled and released, a second balloon may be filled and launched at a selectable time thereafter, etc. The filling and releasing of the balloons is controlled by an electronic control unit which automatically applies the first and second signals at appropriate times.
