The landing gear systems on rotary-wing aircraft come in several different designs.
Some helicopters have a nose landing gear while others have a tail landing gear.
The tail landing gear on both these helicopters is nonretractable. As you can see, helicopter landing gear systems come in several different configurations. The landing gear systems on most of the helicopters used in the Navy use wheel and brake assemblies. The components used in the landing gear system of a helicopter are very similar to those used in a fixed-wing aircraft landing gear system. In helicopters that use retractable landing gear systems, the components and means of actuation are also similar in design to fixed-wing aircraft.
