In summary, the conversation is about understanding how helicopters work and the potential resources for finding information on the topic. The participants suggest searching on the internet and seeking help from engineering forums. One participant also provides a website with information about the mechanics of helicopters. One participant mentions the relationship between helicopter blades and wings, and another mentions the principle of Bernoulli.

Welcome to PF,

To what level do you need to go? Is it for a project? Have you tried searching on the Internet? Perhaps, this would be more appropriate in the engineering forums and one of the mentors would be kind enough to move it?

If you have specific questions, ask away. I echo Hoot's question. To what level of detail do you want to go?

Here's a pretty good site.

Well, the blades are like wings, and they spin round, and the helicopter goes up.


Otherwise, same answer as the others gave.

Think Bernoulli.
 

FAQ: How Do Helicopters Fly Using Bernoulli's Principle?

How do helicopters stay in the air?

Helicopters stay in the air through the principles of aerodynamics. The rotors on top of the helicopter generate lift by creating a difference in air pressure above and below the blades. This lift, combined with the forward motion of the helicopter, allows it to stay airborne.

How do the rotors on a helicopter work?

The rotors on a helicopter work by rotating at a high speed, creating lift and thrust. The angle of the rotor blades can be adjusted to control the amount of lift and thrust generated, allowing the helicopter to move in different directions.

How does a helicopter change direction?

A helicopter changes direction by adjusting the angle of the rotor blades. Tilting the rotor blades forward or backward causes the helicopter to move forward or backward, while tilting them to the left or right causes the helicopter to move left or right. This is known as cyclic control.

What is the purpose of the tail rotor on a helicopter?

The tail rotor on a helicopter is responsible for counteracting the torque created by the main rotor. This torque, also known as the "spin" of the helicopter, is caused by the main rotor blades rotating in one direction. The tail rotor produces thrust in the opposite direction, keeping the helicopter stable and preventing it from spinning out of control.

How does a helicopter hover in one place?

A helicopter can hover in one place by using a combination of the main rotor and the tail rotor. The main rotor generates lift, while the tail rotor counteracts the torque and helps keep the helicopter stable. By adjusting the angle and speed of the rotors, the helicopter can maintain a stable hover in one place.
