The two-stage EMERGENCY RESCUE SYSTEM. The parachute system design is aimed to provide slow descent of the UAS at high speed. It includes two parachutes - the pilot chute and the main chute used to slow and stabilize the UAS. The decrease in the load speed on the UAS occurs due to the main chute opening delay function, when the pilot chute opens first. The parachute system is designed for UAS with speeds of up to 280 mph (450 kph) and weight of up to 110 lb (50 kg).


  • UAV stable descending with main canopy;
  • Absence of parachute collapse phenomenon while UAV descending;
  • Quick and easy replacement of a pyrocartridge;
  • Reusable system.


The following is based on the 75 kg MTOW of UAV
