Details: This poster shows a military helicopter flying over a desert landscape.
A helicopter is an aircraft that is lifted and propelled by one or more horizontal rotors, each rotor consisting of two or more rotor blades. Helicopters are classified as rotorcraft or rotary-wing aircraft to distinguish them from fixed-wing aircraft because the helicopter achieves lift with the rotor blades which rotate around a mast. The primary advantage of a helicopter is from the rotor which provides lift without the aircraft needing to move forward, allowing the helicopter take off and land vertically without a runway. A military helicopter is a helicopter used by military forces. It can be found in a variety of roles in different militaries of which the tactical airlift mission is the most common.
