Mil Mi-8

The Mil Mi-8 is a Soviet-designed, twin-engine medium transport helicopter used for military and civilian missions. Its wide production and export made it one of the world’s most numerous helicopter types.

Helicopter rotor: A rotating airfoil system that produces lift and control forces in a helicopter. The Mi-8’s main rotor supplies lift, while its tail rotor counters torque and enables yaw control.
Mikhail Mil: A Soviet helicopter designer who founded the design bureau responsible for the Mi-8. Mil led the bureau that developed the helicopter and gave the aircraft its name.
Military transport aircraft: Aircraft designed to carry troops, equipment, or supplies for armed forces. Military transport is a foundational role for the Mi-8’s troop and cargo configurations.
Helicopter exports of the Soviet Union: The overseas sale and transfer of Soviet-designed helicopters to allied and other states. Exports spread Mi-8s across military and civilian fleets worldwide.
Sikorsky UH-60 Black Hawk: An American twin-engine utility helicopter developed for the United States Army. The Black Hawk is a Western counterpart with a different design lineage and operating ecosystem.
Turboshaft engine: A gas turbine engine that delivers shaft power to drive a rotor or other machinery. Two turboshaft engines power the Mi-8’s transmission and provide redundancy.
Mil Moscow Helicopter Plant: A Russian aerospace manufacturer and design organization specializing in helicopters. The design bureau developed the Mi-8, while production involved multiple Soviet factories.
Air ambulance: An aircraft equipped to transport patients and provide medical care during flight. Mi-8 variants can evacuate casualties from locations difficult to reach by road.
Warsaw Pact: A Cold War military alliance led by the Soviet Union from 1955 to 1991. Mi-8s became standard utility helicopters in many Warsaw Pact armed forces.
Boeing CH-47 Chinook: An American tandem-rotor helicopter designed for heavy transport. The Chinook carries heavier loads using two main rotors rather than the Mi-8’s single main rotor.
