电子扫描压力测量是70年代在美国NASA兰利研究中心研究成功的一种新型测量技术,其目地主要是解决风洞试验中多点压力测量对扫描速度和测量精度的要求。十多年来,这一测量技术随着集成电路和计算机技术的发展得到进一步的完善和提高,其应用范围也由航空航天扩大到其它工业领域的各个方面。本文将介绍多点压力测量技术的发展,并对电子扫描压力测量系统的主要技术关键问题进行分析。
Electronic scanning pressure measurement is a new type of measurement technology successfully researched by NASA Langley Research Center in the 1970s. Its purpose is to solve the requirements of multi-point pressure measurement in wind tunnel test on scanning speed and measurement accuracy. For more than a decade, this measurement technology has been further improved and improved with the development of integrated circuits and computer technologies. Its application range has also been expanded from aerospace to all aspects of other industrial fields. This article will introduce the development of multi-point pressure measurement techniques and analyze the key technical issues of the electronic scanning pressure measurement system.
