UAVOS Successfully Tests Parachute System

UAVOS has successfully tested its new two-stage parachute system. The new parachute system design is aimed to provide slow descent of the unmanned air system (UAS) at high speed.

It includes two parachutes – the pilot chute and the main chute used to slow and stabilise 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). 
 
The pilot chute allows safe slow descent of the UAV during the main parachute deployment, as well as to open up the main chute at a minimum altitude. 
After landing, the group of the main parachute lines is automatically unfastened to collapse the canopy of the main chute and releases after touchdown to avoid dragging the aircraft along the ground.

Unfastening is carried out by the lock of a three-step release: opening the pilot chute, opening the main chute and release of the group of lines of the main parachute.
 
Aliaksei Stratsilatau, CEO and Lead Developer of UAVOS said: “Computer modeling cannot capture all the complexities. Parachutes encounter turbulent and dynamic airflow, which is almost impossible to replicate with computers. The only way to get a handle on all the possibilities is test.”
