上海飞机制造厂在国产大型客机Y10飞机的试飞中,采用机载激光测高仪测试并配以微机快速处理系统,迅速准确地获得了飞机仪表的气动修正量,包括飞行高度、速度、马赫数的修正和温度恢复系数的测定等。通过理论分析和在波音707飞机上与进口仪表所测试得到的修正量对照,表明机载激光测试的气动修正量准确、可靠。 Shanghai Aircraft Manufacturing Co., Ltd. made rapid and accurate aerodynamic correction of aircraft instrumentation with flight laser altimeter testing and computerized rapid processing system during the test flight of the domestic large passenger aircraft Y10. The flight altitude, speed, Mach number The correction and determination of temperature recovery coefficient. Through theoretical analysis and comparison of the correction values ​​measured with the imported instruments on the Boeing 707 aircraft, it shows that the aerodynamic correction of airborne laser test is accurate and reliable.
