Abstract

A high-output airborne metaldehyde smoke generator was designed for cloud seeding purposes and tested on the ground and in cumulus clouds.

The condensation method was employed for smoke production. Hot exhaust gas from the aircraft engine was diluted with air and used as the carrier gas for metaldehyde powder to evaporate and recondense. An output of 1012 nuclei sec−1 was estimated, effective at −5C.
