Abstract
The invention discloses a middle-boron-content rich fuel propellant with a high burning rate pressure exponent. The middle-boron-content rich fuel propellant is prepared from 20-28 wt% of adhesive system which is composed of an adhesive and plasticizer, 20-28 wt% of oxidizing agent, 10-20 wt% of metal fuel, 5-15 wt% of amorphous boron powder, 10-20 wt% of agglomerated boron, 3-6 wt% of burning rate catalyst, 0.5-1.5 wt% of curing agent and 0.5-6 wt% of modifier, wherein the modifier is selected from one of titanium hydride, fluorene, ammonium nitrate, nanometer ferric oxide, adamantane, anthracene and anthraquinone. By means of the middle-boron-content rich fuel propellant, the burning rate pressure exponent can be increased, and the negative influence on the energy performance of the richfuel propellant is reduced.
