Aeroengine control system teaching device and method

Abstract

The present invention provides a teaching device and method for aero-engine control system. The device and method include: firstly, the operator will complete the programming of the program of the aero-engine digital control system at the engineer station; system; then the operator gives the thrust command of the aero-engine by pulling up or down the throttle lever, and the aero-engine digital control system converts the operator’s command into an actuator command and sends it to the running aero-engine mathematical model; finally The aero-engine mathematical model calculates the current thermal performance characteristics of the aero-engine according to the instructions of the actuator, and feeds it back to the aero-engine digital control system, and at the same time sends corresponding instructions to a demonstration aero-engine physical model for corresponding intuitive state display . The present invention enables students to understand the entire aeroengine control system design, implementation and test run process.

Description

technical field [0001] The invention relates to an aero-engine control system teaching device and method, which are used to demonstrate the design, realization and test run process of the aero-engine control system, and belong to the technical field of aero-engine control. Background technique [0002] Aeroengines are one of the most complex machines ever manufactured, known as the "crown" of the manufacturing industry. The control system, as the "brain" of the aero-engine, needs to ensure that the aero-engine is controlled to work safely, reliably, stably and achieve the best performance under various aerodynamic, thermal and mechanical design constraints, according to the pilot's instructions. The control system is a very important and indispensable part of the entire aerodynamic propulsion system. However, with the multi-objective mission of modern aero-vehicles, the design of aero-engine control systems has become more and more complex, and any small flaw in the design ...

Problems solved by technology

However, with the multi-objective mission of modern aviation aircraft, the design of aero-engine control system becomes more and more complicated, and any small flaw in the design can cause tragic aviation accidents

[0003] On the other hand, the development of aero-engine control systems has gone through mechanical hydraulic, mechanical pneumatic, analog electronic, electronic / mechanical hydraulic hybrid, and now the full authority digital electronic control (FADEC), but its price is still very expensive , the full-authority digital electronic control system of a commercial turbofan engine is as high as several million yuan, and the repair and maintenance costs are also very expensive. As a result, colleges and universities majoring in aero-engine control cannot use these equipment for teaching, and can only stay in full digital simulation teaching stage
