Airplane engine dynamic simulation test bed

Abstract

The invention pertains to the field of 'engine test equipment and test technologies', and relates to an airplane engine dynamic simulation test bed. The airplane engine dynamic simulation test bed consists of a 50-stitch interface definition, a left and right engine full privilege digital electronic controller, an engine electric control unit, an engine vibration detecting instrument, a testing part and a measuring and controlling system. The measuring and controlling system comprises a simulation / dispersion input interface card, measuring and controlling software of an embedded engine simulation model, a sensor simulation unit and an output interface card. The test bad has the advantages of complete function, high intelligent property, fast response time and capability of precisely simulating the dynamic and steady work process and fault monitoring result of the whole flight envelope internal power device system of an airplane by the engine simulation model, an electric simulation technology and a dynamic simulation technology under the condition of no real engine existing. The test bed can be used in the test study of a power device comprehensive control system of the whole system of the airplane and the function study of the airborne testing part.

Description

technical field [0001] The invention belongs to the field of "engine test equipment and test technology". It relates to an aircraft engine dynamic simulation test bed. Background technique [0002] The comprehensive control system of the power plant of advanced aircraft involves the engine full authority digital electronic control (FADEC), the engine electrical control unit (Engine Interface Control Unit (EICU)), the engine vibration detector (Engine Vibration Monitor (Engine Vibration Monitor) The work of airborne control equipment such as EVM)) and the cross-linking work between these equipment and aircraft avionics, flight control, environmental control, landing gear and other systems, the electronic, integrated, and comprehensive degrees between systems are high, and the relationship between systems Complex and interrelated. Therefore, it is necessary to conduct various functional tests and cross-linking tests on the power plant system to verify the function and perfor...
