point本文在分析我院某发动机试车台上安装的DSA3217型气体压力扫描阀结构原理和技术要求的基础上,通过计算并进行理论分析,提出了一种无需对高度差引入的测量误差进行逐点逐通道修正的现场原位校准方法。该方法在解决现场原位校准难题的同时,避免了繁琐的高度差修正工作,从而提高了工作效率。同时,该方法对科研试飞现场其他气体压力参数的现场原位校准工作也具有一定的技术指导意义。
point Based on the analysis of the structural principle and technical requirements of the DSA3217 gas pressure scanning valve installed on an engine test bench in our hospital, a calculation method is proposed to calculate the gas pressure of the DSA3217 gas pressure scanning valve. On-Site Correction Method by Channel Correction. The method can solve the problem of on-site calibration in situ and avoid the tedious correction of height difference, thereby improving the work efficiency. At the same time, this method also has certain technical guidance significance for on-the-spot calibration of other gas pressure parameters on the test flight site.
