前言科学试验是航空科学发展的基础。随着我国航空工业的不断发展,新机研制和航空科学理论领域内的试验任务大量增加。这些试验如飞机的静、动力强度试验、热应力试验、空气动力试验、疲劳试验以及飞行试验等等。其中大部分试验要求在极短时间内测取大最科学试验数据,并尽可能迅速地进行数据处理。有时还需要进行实时控制。正因如此,以计算机为中心的数据采集与控制系统在航空测试自动化过程中正在起着越来越重要的作用。以计算机为中心的数据采集和控制系统一 Foreword Scientific experiments are the basis of aviation science development. With the continuous development of aviation industry in our country, the testing tasks in the fields of new aircraft development and aviation science theory have been greatly increased. These tests, such as the aircraft static, dynamic strength test, thermal stress test, aerodynamic test, fatigue test and flight test and so on. Most of these tests require large scientific test data to be taken within a very short period of time and data processed as rapidly as possible. Sometimes you need real-time control. Because of this, the computer-centric data acquisition and control system is playing an increasingly important role in the automation of aviation testing.
