Study on the influence of some factors on the high burning rate of energy-carrying materials based on acrylonitrile butadiene rubber with end-chain carboxyl group

Abstract

Heterogeneous energy-carrying materials possess outstanding advantages compared to other energy-carrying materials, therefore, research and development of this type of material to create propulsion for flying objects is an inevitable trend in the field of military science and space. This paper presents the results of research on the influence of a number of factors on the technological properties and combustion rate of heterogeneous energy-carrying materials based on acrylonitrile butadiene rubber CKH-10KTP and ammonium perchlorate (AP).The research results show that the combustion law depends on the pressure of heterogeneous energy-carrying materials based on CKH-10KTP and ultra-fine AP (specific surface area 2.61÷3.85 m2/g), using a combustion catalyst ferrocene derivative. The study also determined the optimal content of combustion catalyst - plasticiser to be 3.5÷3.8%. The research results are a solid scientific basis for optimally determining the parameters of radioactivity, energy of energy-carrying materials, supplementing the national data source in the design of aircraft engines, meeting requirements in the new context.
