摘要

数字虚拟飞行仿真计算是一种基于“人-机-环”数学模型的一个完整飞行任务的仿真计算。在方案设计阶段,采用该方法能初步完成飞机飞行品质等级、适航符合性等评定,有效地解决在飞机研制后期若试验/试飞发现问题无法修改设计等问题。对于同一科目不同飞行状态或民机改型有关科目的适航审定等,可直接应用数字虚拟飞行仿真计算的结果,且该计算方法在民机适航审定中的应用日益广泛。较系统地介绍了飞机数字虚拟飞行仿真计算方法,特别是评估飞行任务及数字化与数字飞行员建模方法等,并给出了该方法在民机构型参数设计与使用条件确定、复杂场景的飞行性能精确计算、民机适航符合性评估、军机飞行品质评定和Ⅲ类非线性PIO预测等方面的应用示例。数字虚拟飞行仿真计算为飞机设计、适航取证或飞行品质评定等提供了一套实用的数学计算方法。

Abstract

Aircraft digital virtual flight simulation method is a simulation method based on the “human-pilot-environment” mathematical model for complete flight missions. During the preliminary design phase, this method enables initial assessment of aircraft flying qualities and airworthiness compliance, effectively addressing issues that may be difficult to modify if discovered during flight test. Furthermore, this method proves effective for the airworthiness verification of different flight states or civil aircraft developments in the same flight test course, and is increasingly being adopted in civil aircraft airworthiness verification. This paper systematically introduces the aircraft digital virtual flight simulation method, with particular emphasis on flight mission digitization and digital pilot modeling. Application examples are presented in several areas: civil aircraft configuration parameter design and operating condition determination, precise flight performance calculation, civil aircraft airworthiness compliance evaluation, military aircraft flying qualities assessment, and Category Ⅲ nonlinear PIO prediction. This paper provides a practical digital computation methodology for aircraft design, airworthiness verification, and flying qualities assessment.
