To the question of the description of the internal combustion engine in the mathematical model of the lifting system of the hovercraft (on the example of the ZMZ-51432.10 CRS engine)

Abstract

Introduction. It is known that about one third of the total capacity of the power plant of the hovercraft (SVP) is spent on the creation of an air cushion that ensures the rise of the main hull of the vessel. At the same time, in SVP, the source of mechanical energy, as a rule, is a diesel internal combustion engine (ICE). This article discusses one of the issues related to the creation of a mathematical model of the lifting system of the SVP, using: ICE, hydraulic transmission, axial fans and an air cushion nozzle scheme. Since in the vast majority of cases, the internal combustion engine performs its work in partial load modes, it becomes necessary to effectively control the power of the internal combustion engine in order to achieve its high efficiency in partial load modes.

AIMS. The purpose of this study is to develop a mathematical description of the operation of the internal combustion engine both in external and partial modes of operation, for use in a mathematical model of the operation of the lifting system of the SVP.

Methods. In this study, a ZMZ-51432.10 CRS diesel engine is used for the lifting system of the hovercraft.

Results. Using the data obtained using the DIESEL-RK program for this ICE, in the Microsoft Excel environment, the corresponding trend lines were obtained for them by approximating the points that identify the partial characteristics of the engine with fourth-order polynomials, as well as the dependence of the coefficients of these polynomials on the control parameter of the ICE operation mode .

Conclusion. The developed mathematical description of engine operation can be integrated with various load models when simulating real systems using internal combustion engines as energy sources. This means that it can also be used in mathematical modeling of the SVP lifting system in the MATLAB Simulink package.
The approach proposed in this article makes it possible to build mathematical models of various systems using internal combustion engines, simplifying the study and saving computational time. Also, the results obtained can be of reference value.
