新型运动提示客观测试技术在A320模拟机的实现

Implement Objective Motion Cueing Test on the A320 Full Flight Simulator

飞行员的主观评价一直是运动提示系统的性能和算法调校的依据,也是民航局方鉴定全动飞行模拟机的主要参考标准。受飞行员的主观因素差异的影响,每一台模拟机的运动提示各不相同。为客观评价A320全动飞行模拟机运动提示系统的逼真度,基于国际民航组织于2015年正式发布的OMCT测试技术原理并通过改装加以实现,通过测量信号从飞行仿真模型到运动平台的信号传输的模数和相位差,获得运动提示系统在包线范围内的频率响应特征和传输延迟,并进一步使用OMCT对洗出算法参数进行优化,通过时域测试对比证实动态特性改善明显。

Pilot＇s subjective evaluation has been used for motion cueing tuning and calibration for years, and widely recognized as the major criteria in civil full flight simulator qualification. Due to the diversity of human perception, it is impossible to reproduce the same motion cueing on different simulators. In order to objectively evaluate the A320 full flight simulator motion cueing system performance, an engineering practice has been carried out recently by implementation of the OMCT（Objective Motion Cueing TesOwhich was published by ICAO in 2015. It aims to measure the signal transport delay between the flight model and motion platform, through analyzing the system frequency response within motion envelop, furthermore such test is also used to optimize the parameters of the motion drive washout algorithm. After comparison with time domain test, the system dynamic characteristics can be found significantly improved after tuning.
