Abstract
The study objective is the possibility of thrust augmentation of a turbojet engine due to upgrading the nozzle cluster by installing an external duct of the annular combustor on the engine case, acting as a nozzle. The problem to which the article is devoted is to get a new product with higher operating parameters at minimal cost by upgrading a mass-produced engine. The novelty of the work is in the introduction of an annular combustor into existing engines that are in serial production, thereby reducing the cost of producing a completely new product with greater thrust. During the research, a number of theoretical advantages of a new product based on a mass-produced engine are obtained, including increased thrust with minimal change in its weight, as well as the economic benefits of producing such units with minimal production changeover. At the stage of theoretical research of this topic, a retrofitted engine with an annular combustor has a number of advantages over the standard engine taken as a basis.
