The most common model , the 47g introduced in 1953 , can be recognized by the full bubble canopy , exposed welded - tube tail boom , and saddle fuel tanks 最普通的贝尔47g在1953年投入使用，他拥有一个全玻璃的座舱，和一个暴露的金属管焊接而成的机尾及马鞍状的油箱。
While maintaining constant altitude and speed , execute a 360 degree turn in the opposit direction , the helicopter should flying directly at the pilot again 在降落区的上空将机头朝左保持停悬，向右后退飞行，然后执行外侧3 / 4水平圆，此时机尾朝向操控者后退飞行。
The twin - engine plane was shattered to bits upon impact , leaving only its tail largely intact and a swath of charred ground amid scrub brush at an altitude of 13 , 500 feet 双引擎飞机被撞得粉碎，只留下大部分机尾完整无缺，在烧焦了一大片位于海拔13500英尺的灌木丛。
With the helicopter hovering tail - in , add left cyclic and flip the helicopter to inverted , continue until the helicopter has completed 2 rolls to the left 机尾朝向操控者保持停悬，将副翼打左舵使直升机翻滚为倒飞的姿态，持续地将副翼打左舵使直升机向左完成侧滚二圈。
With the helicopter hovering tail - in pull back cyclic , and work the collective to complete at least two ( 2 ) full back tumbles while maintaining a constant altitude and heading 机尾朝向操控者保持停悬，将升降舵拉升舵使直升机保持固定的高度及方向，向后翻滚至少二圈。
With the helicopter hovering tail - in , add right cyclic and flip the helicopter to inverted , continue until the helicopter has completed 2 rolls to the right 机尾朝向操控者保持停悬，将副翼打右舵使直升机翻滚为倒飞的姿态，持续地将副翼打右舵使直升机向右完成侧滚二圈。
Move the helicopter to the right , keeping the tail pointed at the pilot , in a circle around the pilot . until the helicopter is hovering over the take - off point 保持机尾朝向操控者，以操控者为圆心，以顺时针的方向，执行直径10公尺的水平圆。直到直升机到达起飞点的上空。
B . move the helicopter to the right , keeping the tail pointed at the pilot , in a circle around the pilot . until the helicopter is hovering over the take - off point 保持机尾朝向操控者，以操控者为圆心，以顺时针的方向，执行直径10公尺的水平圆。直到直升机到达起飞点的上空。
While maintaining a constant altitude use the tail rolor to rotate the helicopter clockwise 90 degrees , the helicoper will back to nose - out , hold for ten ( 10 ) seconds 保持稳定的停悬高度，将方向舵打右舵，使直升机顺时针旋转90 ，此时机尾又朝向操控者，保持静止倒飞停悬10秒钟。
Abstract : the scheme of introducing bulk cement tanker and dustless charger for discharing end dust transport system was discussed , and the operating effect was presented 文摘:介绍了马钢三烧在机尾除尘干灰回收工艺中为引进散装水泥罐车和无尘装车机所做的方案论证研究,并介绍了实际改造效果。
