摘要
针对飞翼飞行器不同于常规布局的特点,该文以飞翼飞行器为对象讨论了其气动伺服弹性耦合问题。利用分支模态法建立了考虑刚体动力学的综合动力学模型,并结合控制结构及传感器布放位置获得全机的气动伺服弹性模型,详细讨论了不同高度、马赫数情况飞翼飞行器飞行-控制-结构动力学之间的相互影响关系,并对其耦合的动力学特性进行了描述与分析。该文所得的结论对此类飞机的气动伺服弹性分析和设计具有一定的参考价值。
The aeroservoelastic(ASE) dynamic characteristics of elastic flight-wings are discussed in this study. A coupled dynamic model of a flight-wing is developed using the branch mode method, which considers the interactions between flight dynamics, structure dynamics and aerodynamics. At the same time, an ASE model of the entire aircraft is obtained by integrating controlling structures and sensor layouts. Using this model, the interactions among flight dynamics, controlling structures and structure dynamics for flight-wings are examined at various altitudes and Mach numbers. Subsequently, characteristics of the coupled dynamics are investigated, the conclusions of which are expected to offer referencing information for future ASE analysis and design of aircrafts of similar kind.
