Abstract:

Aiming at the shortcomings of areo engine sensor in the ground test, a deep research is carried out to propose a new mode of hardware-in-the-loop simulation. It solves the problems of traditional complex experimental operation, vulnerable to be interfered and bad scalability. Based on the extensible processing platform Zynq, the simulation system, with suitable embedded systems, transplants the small TCP/IP protocol stack LwIP, which can be connected to the comprehensive experimental network. For different experimental requirements, the scalability is improved and system integration is easy to realized by adjusting the number of devices accessing the network. Users is able to complete a series of operations such as model simulation, parameter verification, and data testing without entering the lab. The results of practical use show that the comprehensive performance of the new simulation system is much better than the traditional mode. It provides an efficient and convenient solution in the simulation and testing of aero engines. Besides, it can improve the experimental efficiency by more than 30% and be successfully applied into poly-type areo engine comprehensive labs.
