摘要：
The features of the gasdynamic wave process occurring in the direct-flow air jet engine channel on starting its combustion chamber or changing the mode of fuel feeding are investigated. In this article, the simulation of the nonstationary processes in the channel is based on the nonstationary quasi-single-dimensional Euler equations containing 'source' terms which describe the influx-efflux of mass, impulse, and energy. The operating process model takes into account some experimental relationships, including the relationship of combustion efficiency to the air excess coefficient and to the intrachamber characteristics.
