Rescue systems GRS 4

0,00 € 0,00 €

The GRS system is designed for quick deployment to enable the rescue of crew and aircraft from the lowest possible height. In other systems the parachute is gradually pulled out from the top, exposing the length of the material to distortion by air currents and damage by contact with airframe or detached parts thereof. The GRS canopy is kept contained in a harness until the suspension ropes are fully extended at 15-18m above the airplane (depending on model), where it is then extracted for safe inflation. This design minimises the danger of damage to the fabric and suspension ropes during deployment. Inflation of the canopy starts in 0,4 to 0,7 seconds from activation of the system. The system is designed with reserve capacity to work even under extreme conditions.
