Research On The Fuel Control System Of Aircraft Engine Test Bed

Summary of aero-engine test bed is an important data such as engine development, shape, measurement simulation testing is an indispensable key equipment, including aero-engine fuel supply system test bed testing equipment is an important part. In order for the aero-engine test-bed to be in normal working condition, while enabling the highest efficiency of fuel burning in the Aero-Engine, fuel must be guaranteed just enter the aviation engine with a constant temperature and pressure. This paper is aimed at aero-engine fuel supply problems, has designed and developed a complete set of temperature and pressure control system for aero-engine fuel, which has a very high value and theoretical significance.The system is based on Siemens S7-200 series PLC (programmable logic controller) as the core, instead of the traditional relay control, thereby solving the lack of poor system design complexity, anti-jamming ability. Of temperature transducers, pressure transmitters, instrument collection, by using PID control algorithm, constant temperature and pressure of the system automatically when insufficient fuel supply, fuel supply. Touch-screen LCD and control cabinet installed, you can set up specific parameters on the LCD. PC communications using Ethernet modules, data transmission over the network, which greatly improves the transfer speed and efficiency. Application of forcecontrol configuration software write PC interface and realizes remote monitoring equipment of operation status, real time and historical, user management, and other functions.In the system’s course of study, the use of PLC technology and improves the reliability of the system, ensuring the proper functioning of the engine fuel, for the development of engines provide a guarantee.
