Torque test system of analogue simulation of VBV fuel oil driving motor of civil aircraft

Abstract

The invention discloses a torque test system of analogue simulation of a VBV fuel oil driving motor of a civil aircraft. The torque test system comprises a dynamometer machine, a dynamometer machine control system, a torque rotating speed sensor, a torque rotating speed parameter collecting system, the VBV fuel oil driving motor and a power test platform, wherein the dynamometer machine control system is connected with the dynamometer machine through a cable, one connection shaft of the torque rotating speed sensor is connected with the dynamometer machine, the other connection shaft of the torque rotating speed sensor is connected with the VBV fuel oil driving motor, the torque rotating speed sensor is further connected with the external torque rotating speed parameter collecting system, and the VBV fuel oil driving motor is further connected with the power test platform. The torque test system can test torque of the VBV fuel oil driving motor under set pressure difference and rotating speed, the torque is compared with a relative torque reference value, whether the VBV fuel oil driving motor reaches the standard is judged, and therefore whether the VBV fuel oil driving motor is safe and reliable is judged.

Description

technical field [0001] The invention relates to a test system for civil aircraft components, in particular to a torque test system for simulating a VBV fuel-driven motor of a civil aircraft. Background technique [0002] The VBV system plays a vital role in engine operation: during constant engine speed and acceleration, it is directly controlled by the angular adjustment point of the adjustable compressor stator vane VSV: at low speed, the low pressure compressor provides The compressed air flow greatly exceeds the air flow required by the core machine. At this time, the VBV valve opens to release the excess compressed air out of the core machine. engine running needs. When the thrust of the engine is reduced, the VBV valve opens, and when the thrust is rapidly reduced, the VBV valve is fully opened, and the compressed air of the low-pressure compressor LPC is discharged from the core engine. At this time, the VBV plays the role of increasing the air flow in the LPC and im...
