随着航空和电子技术的蓬勃发展,近10年来试飞测试技术发生了巨大的变化。传感器的精度明显提高,采集数据的手段几乎完全数字化,磁记录器的记录方式由高密度数字记录(HDDR)、高位记录(HBR)进展到用旋转磁头记录器记录高速率的试飞数据。飞行试验机载测试系统除了敏感、采集、记录试飞参数之外,还可以将参数和景象发送到地面站。飞行试验数 With the rapid development of aviation and electronic technology, the test flight test technology has undergone tremendous changes in recent 10 years. The accuracy of the sensor was significantly improved and the means of acquiring data were almost completely digitized. The recording method of the magnetic recorder progressed from high-density digital recording (HDDR) and high-level recording (HBR) to high-rate flight test data recorded with a rotary head recorder. Flight Test The onboard test system, in addition to sensing, acquiring and recording test flight parameters, can also send parameters and scenes to ground stations. Flight test number
