Increasing the mobility of armored combat vehicles in service with the Russian Army is an urgent direction for improving the weapons and military equipment of the Ground Forces. One of the ways to increase the mobility of combat vehicles equipped with gas turbine supercharged diesel engines is to improve the characteristics of a diesel engine in unsteady operating modes when there is a mismatch in the supply of fuel and the air necessary for its combustion. The analysis of possible technical solutions for the coordination of the hydraulic characteristics of the supercharging units and the diesel engine, and the possibility of their use in the production and modernization of combat vehicles. The optimal technical solution has been determined, which makes it possible to coordinate the air supply to the engine in unsteady operating modes. A mathematical model has been developed to determine the main indicators of diesel engines equipped with turbochargers with an adjustable turbine nozzle, taking into account the specifics of the engine placement in the engine and transmission compartment of a combat vehicle. A technical solution has been proposed for the use of such diesel engines at existing weapons and equipment facilities. The effectiveness of the developed model and technical solution was evaluated in accordance with the approved methods for assessing the mobility of combat vehicles, which showed that the use of the developed utility model will increase the level of mobility of the BBM at low cost.
