Like most aircraft, helicopters use airfoils to make lift. An airfoil is a shape commonly found in the cross-section of an airplane’s wings. The rotor blades that spin on top of a helicopter are also airfoils. The shape of an airfoil controls the flow of air around it. Its primary purpose is to accelerate the air that passes over the top of the air...
One of the essential things that pilots of any aircraft must learn to be able to do is control the amount of lift that their flying machine is producing. Lift is the force that acts opposite gravity. To get the machine off of the ground, the pilot must make their aircraft produce a lift force greater than the force of gravity. The exact amount of l...
Of course, the pitch of the blades is closely tied to the speed of rotation. So as the AOA is increased, more power is needed to maintain the speed of the rotors at a constant RPM. So the simple act of getting more lift from a helicopter is actually very complicated. To increase the AOA, the pilot pulls up on the collective control. This is commonl...
The fact that a helicopter does not have to move forward through the air to maintain its lift gives it the freedomto do things that airplanes cannot. For one, a helicopter can hover motionless in midair. A helicopter can also spin on its axis during a hover. The chopper can start flying in any direction from a hover—forward, sideways, or in reverse...
Jan 11, 2023 · Planes make lift with airfoils (wings that have a curved cross-section). As they shoot forwards, their wings change the pressure and direction of the oncoming air, forcing it down behind them and powering them up into the sky: a plane's engines speed it forward, while its wings fling it up. The big problem with a plane is that lots of air has ...
Whether it's a rotor or a wing, it's the airfoil that generates the lift. The shape and angle of the airfoil in flight makes the air flow faster over the top surface than underneath. The faster the air flows, the lower the pressure. And the difference in pressure between the top surface and the bottom means that the airfoil lifts up.

Why do helicopter rotor blades lift?
The rotor blades of a helicopter are rotating wings that create lift. Lift is generated by the blade shape creating a lower pressure above each blade causing it to rise as it rotates. The pilot changes the pitch angle of each rotor blade to also deflect air downwards allowing for directional control. As a young boy, the sight of a helicopter in ...
