Abstract

The paper presents an analysis of the peculiarities of operation of gas-turbine engines with an afterburner. The main shortcomings of the existing afterburners are described.  The structural design of afterburners is analyzed. It is shown that the existing afterburners do not provide efficient control of the working process throughout the operational range of heights and speeds of flight. Methods of calculating the parameters of the working process organization in the afterburners are specified. The necessity to control the place and the angle of supply of fuel upstream of the flame stabilizer is proved. New operating factors are proposed for the system of automatic control of the afterburner. The use of new structural designs of collector devices incorporated in the afterburner is justified. These devices allow efficient control of the organization of the working process in them throughout the operational range of heights and speeds of flight. The classification of afterburners is specified and the advantages of gas-turbine engines incorporating afterburners with adaptive fuel supply collector devices are justified.
