yawing motion meaning in Chinese
偏航运动
Examples
- Identical autopilots are used to control the pitch and yaw motions if the missile has two planes of symmetry .
如果导弹有两个对称面，则使用相同的自动驾驶仪控制俯仰和偏航运动。 - In this paper , wheel - rail rolling contact creepages and creeps of independently rotating wheel are analyzed , the effects of lateral and yaw motions of independently rotating wheel , and the curve radius to creepages of wheel - rail rolling contact are emphasisatically researched . 4
论文对独立旋转车轮的轮轨滚动接触蠕滑率/力进行了分析，研究了轮对横移和摇头运动以及曲线半径对独立旋转车轮轮轨蠕滑率的影响情况。 - This paper studies optimal helicopter flight operations in the event one - engine failure . a three - dimensional point mass with a yawing motion of uh - 60a has been used to study rto and cto from an elevated heliport or from a heliport , a first order dynamic of the oei contingency power is considered . flight after engine failure are formulated as nonlinear optimal control problems
双发及多发直升机单发失效后,直升机飞行所需要的功率由剩余发动机提供,而在某些需要大功率的飞行状态时,如起飞状态、着陆状态等,剩余发动机提供的功率可能满足不了,这就需要对剩余发动机的可用功率进行合理利用。 - The problem is then fed to a nonlinear programming routine to solve for all parameters . the flight dynamics model with yawing motion of uh - 60a is given , scale factors of state variables and control variables are applied based on the consideration of algorithm convergence . then , the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits , faa regulation and so on
首先,建立带偏航运动的直升机点质量模型,然后对状态变量和控制变量进行无量纲处理,因为状态变量和控制变量量值相差较大,这使得优化算法收敛效果变差,所以需要选择适当的缩放因子,最后把直升机单台发动机停车后的飞行轨迹表示成一个最优控制问题,即在考虑直升机性能限制和far规范后,指定一个优化性能指标,选择合适的路径约束,然后再解最优控制问题。
