飞行模拟逼真度概念

指出定义飞行模拟逼真度时只考虑气动力特性的精度是不够的，其研究应以驾驶员－收音机操纵回路的分析为基础。介绍了在真实飞行和模拟飞行的操纵回路。比较这两个回路可以发现，对于台飞行模拟器来说，某种程度的不逼真性是不可避免，因此必须在需要和可能之间进行折衷。并给出了一些具度和定义和验证以及改善逼真度的方法和经验的讨论。

Inquire into Concepts of Flight Simulation Fidelity

This paper points that just considering the accuracy of aerodynamic characteristics is not enough to define flight simulation fidelity. According to the author's experience,the definition of fidelity ought to be based on the analysis of pilot-aircraft controlling loop. Both the controlling loops in actual flight and in simulation are introduced here. Comparing the two loops, it is found that a certain degree of infidelity is unavoidable for an aircraft simulator, so that a compromise has to be made between the need and possibility.Some definitions of fidelity,and the approaches of verifying and lin proving flight simulation fidelity are also described.
