圆柱段轴线偏转矢量喷管(AT) 这种装置的主要特点是把喷管的圆柱段分为前后两截,在搭接处的左右两侧设置了两个侧向销轴。这样整个排气喷管就可作俯仰平面内的上下摆动,从而获得附加的飞机操纵力矩。该装置的优点是运动原理非常简单,轴对称收-扩喷管可以不作任何改动,A8和A9也无需改变。其最大缺点是转动段长度达1.3米到1.7米,而且转动部位靠前,外阻很大,结构上受到的附加载荷很大,达十几吨。为了抵消这一附加载荷,必须设置笨重的承力
Cylindrical section axis deflection vector nozzle (AT) The main feature of this device is the cylindrical section of the nozzle is divided into two before and after the lap at the left and right sides with two lateral pin. This allows the entire exhaust nozzle to be tilted up and down within the plane, resulting in additional aircraft maneuvering moments. The device has the advantage of the principle of movement is very simple, axisymmetric income - expansion nozzle without any changes, A8 and A9 do not need to change. The biggest drawback is the length of the rotating section of 1.3 meters to 1.7 meters, and the rotating part of the front, a large external resistance, the structure of the additional load is large, up to ten tons. In order to counteract this additional load, heavy loads must be provided
