This is Zefhir, the only helicopter with a ballistic parachute in the world. It’s installed above the main rotor and designed as a backup for conditions where autorotation cannot be performed – this could occur with flight control failure or loss of maneuverability, flying over an area where an emergency landing cannot be performed safely, and flight conditions that prevent restoring rotor rotation speed.
Back in 2018, a breakthrough test confirmed the use of ballistic parachute safety systems in helicopters for the first time. This type of nail-biting test had never been filmed or documented in the entire history of aerospace technology. The revolutionary technology was tested at the Oristano-Fenosu airport in Sardinia, Italy.

The helicopter had reached forward flight at 30 knots above 300 meters of altitude and an engine was purposely turned off to simulate its failure. The deceleration was stabilized and its ground impact was within the parameters to save human life.
