基于飞/推一体化模型的TOC研究

TOC Research Based on Flight/Propulsion Model

为了研究大型民航机在失去部分或全部液压系统时,能否仅依靠推力变化来控制飞机姿态,使其安全降落,将发动机部件级模型和波音747-100运动模型结合,介绍了民航机飞/推一体化性能模型建模方法,并在此基础上研究了仅靠推力变化控制飞机姿态的效果。论证了TOC控制的可行性,测试了TOC在飞/推一体化模型上的控制效果。结果证明,TOC能在飞机控制面失效时作为主要控制手段较为有效地控制飞机姿态,满足飞机在紧急情况下的控制要求。

In order to research whether civil aircraft can control its attitude and landing safely with only thrust change when it lost part or all of the hydraulic system. The component-level engine model is combined with B747-100 kinematics model, the preformance modeling of commercial aircraft flight/propulsion is introduced,and the effect to control the aircraft＇ s attitude with engine thrust only with it is researthed. The feasibility of TOC is demonstrated, the effect of TOC on flight/propulsion model is tested. Results show that the TOC is capable of controlling aircraft attitude effectively as main means while the control surface is out of control and can meet the aircraft＇ control requirements in emergency situation.
