Solution Burner for Weather Modification - Advanced Development of an Airborne Jet Seeder.
Abstract
As part of a cold cloud modification subsystem, the Naval Weapons Center has designed, developed, and tested an airborne jet seeder (AJS), which operates on the ramjet principle. Under approximately 120-lb/sq in. pressure, a swirl nozzle sprays a solution of silver iodide, ammonium iodide, and acetone into a chamber, where it is mixed with air and burned. From each gram of silver iodide in the solution, about 10 to the 14th power silver iodide particles (nuclei), each with a radius of not more than 0.2 micron, are delivered from the aft end. Users can vary nozzle size and solution concentration to optimize the count for particular missions. The AJS operated successfully at various speeds and altitudes when flight-tested with a Cessna 337 aircraft. Acetone solutions containing up to 10% of silver iodide ignited and burned. Solutions of 10% lithium chloride dissolved in methanol and acetone burned, also. Under consideration are design modifications to adapt the AJS for burning other solutions that would produce particles useful for generating smoke, measuring air currents, picking up atmospheric contaminants, and for meteorological research.
