摘　　要：通过对航空机电液压、环控、燃油等专业产品地面试验器的压力测量系统进行调查,发现了其存在的可计量性问题,本文将航空机电产品地面试验器压力测量系统的可计量性问题分为技术指标不合理、测量仪表选择不合理、管路及设计不合理、试验器布局不合理四个方面,逐一进行介绍,最后为改进航空机电产品地面试验器压力测量系统可计量性提出了可行性建议。Through the investigation of the pressure measurement system of the ground tester of the aviation electromechanical hydraulic,environmental control,fuel oil and other professional products,the existing problems of the measurability are found.In this paper,the measurability problems of the pressure measurement system of the ground tester of the aviation electromechanical products are divided into unreasonable technical indicators,unreasonable selection of measuring instruments,unreasonable pipeline design and unreasonable layout of the tester.Four aspects are introduced in detail one by one.Finally,three suggestions are put forward to improve the measurability of the pressure measurement system of the ground tester of the aviation electromechanical products.
