autohelisüsteem

Autohelisüsteem, often translated as automatic helicopter or auto-rotor system, refers to a crucial safety feature in rotorcraft designed to prevent catastrophic failure in case of engine malfunction. Its primary function is to allow the helicopter to descend safely and land in a controlled manner even without engine power. This is achieved by the phenomenon of autorotation, where the upward flow of air through the rotor disc, generated by the helicopter's descent, keeps the rotor blades spinning. This continuous rotation generates lift, allowing the pilot to maintain control during the descent and flare the aircraft for a landing.

The effectiveness of autorotation depends on several factors, including the helicopter's altitude, airspeed, rotor RPM, and the pilot's skill in managing the descent. Pilots undergo extensive training to master autorotation techniques, as it is a critical emergency procedure. Modern autohelisüsteem designs often incorporate advanced control systems and rotor dynamics to enhance safety and predictability during such events. While the term itself might be less commonly used in everyday English discussion, the underlying principle of autorotation and the systems that facilitate it are fundamental to helicopter safety worldwide.
