Gas generator development for the ejection of particles, generating aerosol clouds

The controlled generation of particle clouds in the surrounding atmosphere is of interest in several research projects of ICT. Gas generators yield a rapid gas production, the rate of which can be adapted to the specific needs of the application. A gas generator formulation for the ejection of particles was developed and tested concerning their safety parameters, thermal and interior ballistic behaviour. The formulation showed good results with respect to the specified application. The influence of the formulation on the particle dispersal behaviour was investigated in a mock up by means of pressure and temperature measurements and the ejection process by high speed video cameras.
