Abstract:

The results of preliminary upper atmosphere release package design studies are presented in this report these include a parametric series of thermochemical equilibrium calculations, pressure-time history calculations following steady burning and explosive releases and estimates of the position of atomic Fe vapor condensation onset during the expansion of Flashbulb combustion products to ambient pressure. Results of the latter calculations show that homogeneous nucleation will be frozen for Flashbulb combustion pressure less than about 10 atm.
