K8飞机自由飞模型飞控系统设计研究

The Flight Control System Research of Free-Flight Model for K8 Aircraft

自由飞模型是按相似原理以飞机模型空中投放试验来验证原型飞机的操稳性能或获取飞机参数等。现通过对K8飞机自由飞模型控制系统的研究，设计了静不稳定飞行状态下的控制增稳系统。并根据自由飞的特点，设置控制器接通与否两种工作状态，可进行人工操纵飞行和接入控制器的操纵飞行。飞行记录表明，控制系统设计是成功的，可起到对原型机仿真的作用。

Free-flight of aircratf model which is kindred to prototype aircraft is used to validate the performance of prototype aircraft and/or get its parameters. This paper develops a CAS (Control Augmented System) for static unstable model. There are two working modes in the CAS: direct link mode and normal mode. Flying records show that this fight control system is successful and free-flight model can simulate the prototype aircraft.
