KARI has been developing key helicopter technologies such as an anti-torque system, next-generation torque system, and bearing-free rotor hub to help that can be applied to develop Korean helicopters.
KARI participated in the Korean Helicopter Program (KHP) and as the managing agency responsible for the development of key modules of 'Surion', which can be used for dual civil-military purposes. It cooperated with diverse enterprises and universities in Korea and overseas on the development of 18 key units, including the rotors, engine, auxiliary drive system, fuel system parts, pressure accumulator, hydraulic oil pump, landing system, and air data system.
Moreover, it constructed the helicopter development infrastructure - including testing equipment and facilities for rotorcraft development, and a whirl tower testing facility to test rotor performance, dynamic properties, and durability - at the Goheung Aerospace Center, and expanded the open wind tunnel testing unit which is suitable for testing rotorcraft, as part of the Surion Development project.
Utilizing the technologies and infrastructure acquired as part of the Surion Development project, KARI is developing the main rotor blade, automatic flight control system, (AFCS) and active vibration control system as the key technologies of the light civilian helicopter (LCH).
