为什么定翼飞机和直升机的著陸模式是如此的不同?

当我學飛直升机時,已经學了定翼機。所以有以上这个问题。直升机的降落過程,是沿著一條直線下降軋,逐渐减少速度和高度。而定翼机的降落過程,是在低速飛行下,最後制停著陸,跳伞也是用類似的方法。

直升机也可以像定翼机,在低速飛行下,最後制停著陸。但要快速停止,你需要把直升機拉到高高昂起,这涉及大量的协调,在较短的时间要求非常高的技術。

這種降落方式當遇上任何其他不利条件(例如重負載,尾风,阵风),很有可能會导致灾难性後果。

Why the approach in helicopter is so different from fixed-wing aircraft ?

When I learnt helicopter flying, I already had the FW license.  I had this question in mind.  The helicopter approach is normally through a glide path where you gradually reduce the air-speed and altitude together.  For FW approach, they keep flying at low air-speed and flare at the end which is like the flare in parachuting or quick stop in helicopter.

Helicopter can do the same thing like the FW, to fly at low air-speed and terminate by a quick stop.  But, in quick stop, you will need a high nose altitude.  That will involve a lot of coordinations in short time which demands very high skill.

Trying to land with a nose high attitude along with any other unfavourable condition (i.e., high gross weight, tail wind, gusty wind) is most likely to end in disaster.

Hello All !

I build this blog to share the helicopter flying experiences. Why helicopter instead of fixed-wing airplane ?  Because its more practical and enjoyable to fly helicopter than FW.
