Justification of methods for reducing ground-level gas pollution from operating aircraft engines

Abstract

A detailed narrow-minded survey was carried out on one of the three zones of the technological infrastructure of a specialized facility - a hangar for aircraft. A general list of pollutants discharged into the air zone of the facility on the 2nd site with differentiation into 4 sections with eruption generators is established. It has been recorded that environmental indicators of air pollution do not exceed the norms of maximum permissible emissions and maximum permissible concentrations of harmful substances. It was noted that for one ingredient NO2, an analytical assessment indicates a certain excess of the MPC for the energy and test section of the special facility and additional procedures are needed to protect the atmospheric air. The techniques and procedures of the organizational and technical regulations that minimize the accumulation of contaminants (gases) of functioning aircraft engines are analyzed and recommended. A method is proposed for reducing surface gas pollution from operating aircraft engines based on an analysis of environmental protection measures at specialized facilities. The method is based on variations in the orientation of the outflow of gas flows from functioning aircraft engines during launch, taxiing, takeoff, landing, passage of an aircraft along the airfield.
