Abstract

The invention provides a modeling simulation method of turbojet engine modified hot snow blowing device equipment, and belongs to the technical field of turbojet engine modeling simulation. Accordingto the method, the composition and the working principle of the engine are analyzed; an air inlet channel model, an air compressor model, a combustion chamber model, a turbine model, a bent exhaust channel model and an exhaust nozzle model are established; system model modeling of the whole snow blowing device is completed through joint simulation between the models, then engine steady-state worksimulation analysis is carried out, the danger and cost of actual test run are effectively avoided, and the method can serve as a reference basis for control and fault diagnosis of the hot snow blowing device.

Description

technical field [0001] The invention belongs to the technical field of turbojet engine modeling and simulation, and in particular relates to a method for simulating the actual turbojet engine working condition by using computer simulation technology. Background technique [0002] At present, the method for removing important and critical road surface ice quickly and in time is to use the high-speed and high-temperature exhaust gas of a turbojet engine to blow off road snow and thin ice. The turbojet engine is placed on the chassis of the truck. The high-speed and high-temperature engine exhaust passes through the exhaust hood and duct, and is blown to the road surface by the nozzle. Remove the thin layer of road surface ice in important and critical places. [0003] Retrofitting the turbojet engine into a deicing device has high deicing efficiency and complete deicing, but the cost of deicing is relatively high. Using computer simulation technology to establish a turbojet ...
