Discover Zefhir’s exclusive parachute rescue system and the unique turbine helicopter destined to become the go-to brand for air mobility. Zefhir is the first helicopter in the world to be fitted with an innovative ballistic parachute rescue system.
Installed above the main rotor, the parachute is designed as a backup for conditions where autorotation cannot be performed, such as: flight control failure or loss of maneuverability; flying over an area where emergency landing cannot be performed safely; flight conditions that prevent restoring rotor rotation speed.
If you can, autorotate. But if you can’t, the parachute will save your life!During the test, the helicopter reached forward flight at 30 knots above 300 meters of altitude. The engine was then deliberately turned off to simulate its failure. The helicopter’s descent speed stabilized at less than 7.5 m/s (27 km/h).
The ground impact resulted in deceleration peaks well within those required for the safeguarding of human life as routinely assessed in crash tests for the aeronautic and automotive industries.
The system is in fact designed to save the crew’s lives, not necessarily the airframe.The parachute canopy was fully deployed in about 6 seconds, leading to a minimum deployment altitude of 150 meters (450ft).//zefhir
