第二百三十四章 每秒下坠102米!(1 / 2)

鹰掠九天 仲渊2 1194 字 2022-05-01

银灰色L-15C猎鹰拖着修长的尖状威严,恍若雄鹰,露出凌厉气势,迎头掠向更高的天空。

五千米!

七千米!

一万米!

穿梭薄薄的高空积云层之后,机尾挂着两条修长而久久不能散去的尾迹云,整架战鹰爬升到永远蔚蓝的万米高空。

这里空气稀薄,世间仅有少数人踏足,有资格欣赏到永远不会厌倦的绝美风景。

伴随着高度不断增长,空气愈发稀薄,两台WS-17涡扇引擎输出的动力逐渐减少,灵活而轻巧的L-15C猎鹰,渐渐如同缓慢的蜗牛,机动性和爬升效率呈线性下降趋势。

一万两千米。

一万三千米。

十数秒后,笨拙缓慢的L-15C猎鹰爬升至预定高度,机头前压改变自身迎角,平稳改出飞行。

“现在放杆,按照下坠姿势,尾旋一般分为三种,机尾朝下,机身水平,机头朝下,其中机头尾旋最容易改出,机身水平尾旋难度其次,需要将水平改为机头尾旋,机尾朝下尾旋最危险也最难以操控。”

待爬升到预定高度后,杨晓龙顺势接过机体控制权,透过无线电通信器,向周海仔细讲解关于尾旋的情况:“飞机之所以出现不同尾旋姿态,与失速之前的动作和重心分布有关,失速不一定尾旋,而尾旋则必然处于失速状态。”

“嗯。”

周海安静聆听,杨晓龙一番讲解之中,既包含早已熟知的航空理论知识,也有珍贵的个人飞行经验。

失速尾旋改出——这个充满极高危险性的训练科目,必须慎重对待,周海可不会掉以轻心。

“周海,处理失速尾旋最重要的一点,冷静,冷静!在飞机进入失速尾旋状态后,决不能着急慌乱,避免盲目操作。”

杨晓龙平稳握着操纵杆,保持机身水平姿态,强调道:“去年一架山鹰高教在训练高空失速尾旋改出的时候,就因为学员太过紧张慌乱,胡乱拉杆,导致机头朝下变为机尾朝下姿态,又遇到高空乱流影响,最后无法改出,只有弹射跳伞,浪费国家一架宝贵的战机和资源。”

“学员和教员呢?”周海听到这番话,心中一沉,轻声询问道。

“两个人平安,没什么大碍。处置尾旋,时间最为重要,一万四千米的高度,我们大概有140秒时间,在机头尾旋状态之下,我们要油门归零,让发动机处于慢车状态,压杆向前,保持俯冲控制杆位。”

杨晓龙声音沉稳而有力,缓缓仔细讲解处理尾旋的相关步骤和内容:“这时候,迅速判断尾旋方向,假设向右围绕竖轴旋转,我们需要踩满旋转方向相反的左侧方向舵,进而减缓或消除旋转,这时候飞机姿态稳定,气动舵面恢复作用,平稳向下加速,即可改出飞行,记住了吗?”

“记住了。”

周海听完关于杨晓龙的仔细讲解,对于失速尾旋改出的操作步骤和过程已有基础概念,深呼吸一口气,回应道。

复杂!

真的复杂!
