Improving the completeness of combustion of boron particles in a solid-fuel ducted rocket owing to distributed air supply to the secondary combustor

Abstract

A model of combustion of boron particles in ducted rocket using distributed air supply to the secondary combustor was developed for the first time. The completeness of boron combustion in ducted rocket using air supply to the secondary combustor through one outlet or two outlets (distributed air supply) was calculated. It was shown that, in some cases, distributed air supply significantly (by a factor of 1.5–3) decreases the time of complete combustion of boron particles and thereby increases the completeness of fuel combustion in ducted rocket. The modeling results agree with the known experimental data.
