Abstract
In work results of experimental study of influence dispersion of metal powder on burning rate in mixed solid fuel are provided. As metal fuel used additive of aluminum of different type depending on dispersion of powder. The prepared samples of mixed solid fuel were tested in constant volume combustion chamber. The received results of burning rate show that at reduction of dispersion of aluminum powder the burning rate of mixed solid fuel increases.
Highlights
The use of high-energy materials nowadays is important [1]
Gas generators which generally represent solid-fuel element which consists of mix components the including fuel and oxidizer
The solid-fuel charge of the gas generator has a sufficient amount of oxidizer for combustion in a vacuum
Summary
The use of high-energy materials nowadays is important [1]. High-energy materials are widely used in different areas, in fire-extinguishing systems, orientation of spacecraft, rescue operations etc. [2, 3]. The solid-fuel charge of the gas generator has a sufficient amount of oxidizer for combustion in a vacuum. These types of solid fuels are explosive and dangerous during their production, storage and transportation. New types of gas generator and engines, operating on metallized mixed high-energy materials, are characterized by a wide range of variation of the regime parameters, for example, the pressure, the relative content of the components, and the metal fuel content and its dispersity. For ensuring increase of power characteristics a combustion catalyst is added to the solid fuel composition or metals powders and their oxides into composition of the mixed solid fuel (MSF) [4].
