Abstract:
This paper presents the results of an experimental study of the ignition and slagging characteristics during combustion of boron-containing solid propellants with ammonium perchlorate as an oxidizer under conditions simulating working processes in a gas generator and in the afterburner of a rocket-ramjet engine. It is shown that the introduction of fluorine-containing additives into the propellant reduces the content and adhesion of primary condensed combustion products (slags). The dependences of the ignition delay on the density of the radiant heat flux in the range
20–180 W/cm$^2$ are obtained for model solid propellants containing boron, carbon, boron carbide, and slag particles collected in the gasifier.
Keywords:
rocket-ramjet engine, boron-containing solid propellant, primary combustion products, slagging, radiant heat flux, ignition delay.
