What is helicopter pitch
Helicopter pitch is an important concept in helicopter flight control, which directly affects the lift, speed and stability of the helicopter. This article will introduce in detail the definition, classification, function and related hot topics of helicopter pitch to help readers fully understand this key technology.
1. Definition of helicopter pitch
Helicopter pitch refers to the angle between the helicopter rotor blades and the plane of rotation. By adjusting the pitch, the pilot can change the amount of lift generated by the rotor, thereby controlling the helicopter's climb, descent, or hover.
2. Classification of helicopter pitch
| Type | Description |
|---|---|
| Overall distance | All rotor blades change the same angle at the same time, which is used to control the vertical movement of the helicopter. |
| Periodic distance | The rotor blades periodically change angles during rotation to control the attitude and direction of the helicopter. |
3. The role of helicopter pitch
1.Control lift: By adjusting the collective pitch, the pilot can increase or decrease lift to achieve climb or descent.
2.Adjust posture: Changes in periodic distance can change the pitch and roll attitude of the helicopter.
3.Improve efficiency: Optimizing the pitch can reduce energy loss and improve flight efficiency.
4. Recent hot topics and hot content
The following are the hot topics and hot content about helicopter pitch on the Internet in the past 10 days:
| topic | heat index | Main content |
