摘要
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 was a new measurement technique developed in NASA Langley Research Center in 1970s'. The goal was mainly to im prove the scanning rate and the measurement accuracy of multi-point pressure measurement in Wind Tunnel tests. With the development of integrated circuit and computer. this technique has been improved and enhanced for the past 10 years, and its using range has been expanded from aerospace research to industrial application field.The paper discribes the development of electronic scanning pressure measurement technique, and analyses some main key techniques of the new electronic scanning pressure measurement system.
