Examples
- A parametric analysis of the inviscid effects of leading edge sweep , sidewall compression , width - height ratio , cowl position and inflow mach number on spillage is finished . numerical simulations are completed for a series of inlets at various flight height and velocity . the research indicates that the area of spillage window , which is mainly determined by the position of the cowl , significantly influences the spillage characteristic of the scramjet inlet
阐明了侧板后掠的侧压进气道设计参数对构型溢流影响;对不同侧板配置方式的侧压式进气道进行了数值模拟,通过对比分析,发现由唇口板的位置所决定的溢流窗面积的大小对进气道溢流特性的影响显著。 - To solve the problems caused by the varieties of the missile dynamics with the difference of flight height , velocity and attitude angle in modeling the missile , in this thesis , the theory of variable structure model reference adaptive control is used to design a pitch channel autopilot based on a longitudinal missile model , the status equation using the measurable parameters of load and angular rate is established , and the methodology to choosing the reference model is discussed also , and the performance of the controller is analyzed by means of simulation
为了解决拦截弹气动参数随飞行高度、速度、姿态的不同，变化范围大，控制系统难以准确建模的困难，基于纵向平面拦截弹模型，采用模型参考变结构控制理论设计了俯仰通道姿控复合控制系统，以可测量变量过载和角速度作为状态量建立了系统的状态方程，讨论了参考模型的选择方法，并对系统的性能作了仿真分析。
