在采用试验机研究一种全新的气动布局飞机过程中,模拟技术扮演着日益重要的角色。 通常用于研究飞行试验的模拟可分为五类:非实时(分批处理)模拟、实时全软件模拟、硬件环路模拟、铁鸟模拟、飞机环路模拟。其中分批处理模拟不与模拟座舱相连,而是单独在使用者的工作台上操作。实时全软件模拟包括模拟飞机座舱但不包括飞机的其它部分;硬件环路模拟系统是在实验室中使飞行与模拟计算机对接,它用来支持造价比较低和容易控制环境下的飞行计算机试验。“铁鸟”习惯于用来代表完全用于地面试验的飞机, Simulation technology plays an increasingly important role in the testing of a completely new aerodynamic layout aircraft using a testing machine. Commonly used to study flight test simulation can be divided into five categories: non-real-time (batch processing) simulation, real-time full software simulation, hardware loop simulation, iron bird simulation, aircraft loop simulation. The batch process simulation is not connected to the simulated cockpit, but operates on the user’s workbench alone. Real-time full software simulations include simulating the cockpit but excluding the rest of the aircraft; the hardware loop simulation system interfaces the flight to the analog computer in the lab and is used to support flight computer testing in relatively inexpensive and easily controlled environments. “Iron bird” is used to represent the plane completely used for ground tests,
