Ice nucleus testing of th airborne jet seeder

John Carroz, Dennis Garvey


The airborne jet seeder was designed in 1971 and 1972 at the  Naval Weapons Center to burn solutions of silver iodide,  ammonium iodide, water and acetone. Based on the findings of Donnan, et al. the generator was constructed so as not to heat  the silver iodide nuclei to too high a temperature. The burner  design is similar to the stratified combustion engine being developed by Honda Corporation for automobiles. In the jet seeder, solution is  sprayed and mixed with a small portion of air, and combustion begins in this "rich" mixture. The burning mixture is then rapidly  mixed with an excess of air, which cools the mixture so that the  temperature does not rise above 700 C......
