The Thermo-Gas-Dynamic Modeling of Afterburning Turbofan Engine for High Maneuverable Aircraft Combined with Its Automatics

摘要

The article considers modeling of aviation afterburning turbofan engine combined with its electrohydromechanical automatic control systems, supervision and diagnostics for high maneuverable aircraft. It describes an aviation engine and its automatic control system Dvig_Otladka2 developed based on Framework SAMCTO imitating simulation system. The designed imitation models sensors, regulators and actuating mechanism are described. A description of automatic control system action of one of modern aviation afterburning turbofan engine IV generation is presented; the change of main engine parameters by simulating of transient process of afterburner engagement and appearance on the augmented maximum rating are analyzed. The described technology of thermo-gas-dynamic simulation of aviation engines combined with its automatic control system allows selecting and optimizing the control and regulation programs considerably to accelerate fundamental phases of aviation engines design.
