用在飞机上的自动控制技术目前已有了令人瞩目的发展,这是由于实现所要控制规律的飞行电气控制系统的能力有了显著的进步。采用先进的飞行控制技术的飞机在进行飞行试验时所化的费用,所遇到的复杂性和所冒的风险不断上升。于是人们就利用模拟技术研究飞机的动力性能,这种方法就成为一种重要而又有高费效比的手段。只要借助一台模拟机,数字机或混合机就可以进行飞机动力学的模仿和模拟。此外,如要取得大一点的逼真度或直观性也可使用模型自由飞的方法。不过,进行真实的自由飞模型试验以研究飞机动力学中的稳定性和操纵性问题,其费用,复杂性和结果的不易判定等问题使有效地使用这种方法困难重 The automatic control technology used on airplanes now has a remarkable development, due to the remarkable progress made in the capability of the flying electric control system that realizes the desired control law. The cost, complexity and risk posed by aircraft using advanced flight control technology during flight tests are on the rise. So people use simulation technology to study the dynamic performance of aircraft, this method has become an important and cost-effective means. With just one simulator, a digital or hybrid machine can simulate and simulate aircraft dynamics. In addition, the model can be freely fly if you want to get a bit more realistic or intuitive. However, carrying out a true free-flight model test to study the stability and maneuverability issues in aircraft dynamics, the cost, complexity and inconvenience of determining the results make it difficult to effectively use this method
