The cyclic and collective controls affect the attitude of the main rotor disk(s), but how does that control input transfer to the disk? The answer is the swashplate.
The video below explains how the helicopter swashplate works, demonstrated on...
All helicopters have at least one main rotor for lift, but there are many helicopter rotor configurations:
Traditional or Conventional like the Robinson R22
Tandem like the CH-47 Chinook
Transverse like the V22 Osprey
Coaxial like the...
All helicopters have at least one main rotor to produce the lift that keeps helicopters in the air. The type of main rotor system is defined by how the blades are connected to the rotor hub. The blades may have hinges or bearings to allow them to feather,...
Single rotor helicopters require a way to counter the torque created by turning the main rotor. There are three such options:
Traditional tail rotor
Ducted fan or Fenestron
The video below covers the three different types...
Most small training helicopters are powered by lightweight, air-cooled piston engines.
Piston engines are not as powerful as turbine engines, but they are a lot cheaper, hence they are popular in smaller helicopters.
The video below explains...
Helicopters have many rotating parts and vibrations are inevitable. But sudden increased or new vibrations can lead to catastrophic failure of components.
Helicopter vibrations can be broken down into the following by frequency:
Turbine engines are used in most medium to larger helicopters and are also used in some smaller helicopters. They provide a better power-to-weight ratio than piston engines but are more costly.
The video below explains how the helicopter turbine...
