Aerospace Instrument-Making Annotation << Back SYNTHESIS OF SYSTEM OF SYNCHRONIZATION OF OPERATION MODES OF ENGINES OF THE POWER-PLANT OF THE HELICOPTER S.G. Mikrjukov V.N. Efanov A.A. Zajtseva The task of synchronization of engines within the limits of a multiimpellent power-plant of the helicopter is considered. The purpose of such synchronization consists in preventing of inadmissible operation modes and in support of the uniform expenditure of a resource by each of engines. The analysis of the modern approaches to the synchronization, the laws of regulation of frequencies of rotation connected to change and creation of an additional circuit of regulation on the parameters is carried out, allowing to estimate allocated capacities of engines and to align their values. A mathematical model of the power plant, consisting of two helicopter turboshaft engines with free turbines, for a total of loaded mechanical transmission, which drives the helicopter rotor. Formation of mathematical models implemented in three phases. Initially, item-based universal nonlinear engine model, which reflects the physical interaction of individual components and peripherals. Next is the linearization of the model to obtain a mathematical description that is suitable for design problems. In the third stage added to the resulting model equations describing the control of the system. The method of synthesis of a man-agement system a helicopter power-plant on the complex of parameters providing syn-chronization of operation modes of engines taking into account requirements to quality of managerial processes is offered. Key words: synthesis, synchronization, power-plant, helicopter. Contacts: E-mail: efanov@mail.rb.ru Pp. 03-09.
