| Popis: | An analysis of the problems that arise when dealing with issues of increasing the efficiency of using an afterburner as part of a current aircraft engine is presented, where the complex problem of reducing its influence in non-afterburning operation and improving the work process when using it is solved. In a number of cases, solving the problem comes down to a compromise which does not allow full realization of all the advantages of the design element in question. The results of a study of the influence of the method of gas-dynamic flame stabilization on the main target indicator – specific fuel consumption in a real engine are presented, which makes it possible to justify conducting this kind of research on a real object. Graphs of changes in specific fuel consumption and thrust of a gas turbine engine when changing the engine rotor speed for non-afterburning operating modes are presented, as well as graphs of changes in specific fuel consumption and thrust of a gas turbine engine when changing the speed of the aircraft for afterburning operating modes. A conclusion is drawn about the expedience of using gas-dynamic flame stabilization in the afterburner from the point of view of its effect on specific fuel consumption. |
