pitch plane meaning in English

节面
节平面

When a position gyro is used in the pitch plane the missile is usually launched at a set elevation .
当位置陀螺用在俯仰平面上的时候，导弹通常以一个设定的仰角发射。
To overcome the shortages of the traditional proportional guidance in attacking maneuvering targets , the paper firstly established the relative motion models for the anti - ship missile and the target in three dimensions , then based on the optimal guidance law for aiming at non maneuvering targets and the sliding - mode control theory , the optimal sliding - mode guidance law in three dimensions , which was more easily - accomplished in engineering , was derived by making the pitch plane and yaw plane superposition
摘要针对传统比例导引法攻击机动目标的不足，建立了三维空间中反舰导弹和目标的相对运动模型，在研究反舰导弹攻击非机动目标的最优制导律基础上，利用俯仰和偏航两个平面相叠加的方法，结合滑模控制理论设计了工程上易于实现的三维模型下的反舰导弹最优滑模制导律。
