On the issue of increasing the efficiency of the workflow in the combustion chamber of the evaporative type of aviation gas turbine engines when operating on fuel with an anti-turbulent additive

The work is devoted to the analysis of the effect of an anti–turbulent additive, polyisobutylene, on the working process (ignition and combustion of kerosene) in the combustion chamber of an evaporative type of an aviation gas turbine engine. Gorenje is a member of the Russian Academy of Sciences. Experimental values of the ignition induction period of kerosene with the addition of polyisobutylene up to 1% by weight, obtained in an impact tube, are presented. Ignition was carried out in the temperature range up to 1600 K at pressures up to 0.25 MPa. Calculated data on the effect of the ignition induction period on the coefficient of completeness of combustion of TC-1 kerosene with polyisobutylene in an evaporative type combustion chamber of an aviation gas turbine engine are presented. A comparison of the calculated and experimental values of the coefficient of completeness of combustion in evaporative-type combustion chamber in the range of values of the coefficient of excess air from 3 to 7. The results obtained are intended for use in the design of evaporative-type combustion chamber of aviation gas turbine engines.
