Life support systems for manned space ships and civil aviation vessels, disperse assessment method composition of alkaline metals peroxide compounds

To calculate the parameters of human life support systems for manned aircraft, a method is proposed for determining the disperse composition of peroxide compounds of alkali metals and their mixtures, based on inertial separation of particles. A relationship has been established between the dispersed composition of composite mixtures of alkali metal peroxide compounds based on potassium superoxide, obtained from hydrogen peroxide and potassium hydroxide in a spray reactor with a chemical composition that can be varied during synthesis. On the basis of the calculated estimate, it was proposed to use an alkali-resistant BMD-K glass fiber made of super-thin staple fiber as a filter in life support systems. The efficiency of the filtration system of alkaline aerosols of the smoke-protective hood of the oxy-gen system of the MC 21 and SSJ NEW airliners, proposed on the basis of the calculations carried out according to the original method, was 99.4%. During the research, it was experimentally revealed that the main mass of the retained dust is made up of particles with a size of 10 ÷ 40 μm and their conglomerates, the average size of which is 50 ÷ 70 μm, which fully corresponds to the calculated parameters obtained using the proposed method.
