Effects of Fules on Primary Combustion of Boron Based Fuel-rich Propellant

The explosion heat(Qv),the combustion temperature(Tf) and the combustion gas generation rate(η) of boron based fuel-rich propellant contained Mg,Al and magnalium were tested to comparatively study the effects of the metal on its combustion.Results show that Mg improves Qv,Tf,η of propellant better than Al,and the magnalium decreases the Qv,Tf,but increases η higher than Mg.Compared with moderately boron,the coarse or fine boron increases the Qv,Tf higher,and decrease the η lower.The explosion heat,the gas generation rate decrease and the combustion temperature increases with the increasing of the boron content.
