Designed To Help UAS Traveling At High Speeds

UAVOS has successfully tested its new two-stage parachute system, which is designed to help UAS traveling at high speeds slowly descend to the ground.

The system includes two parachutes: the pilot chute and the main chute used to slow and stabilize the UAS. The pilot chute allows the UAS to slowly descend safely during the main parachute deployment. It also allows the main chute to open up at a minimum altitude.

After the pilot chute opens, the main chute’s opening delay function causes the decrease in the load speed on the UAS. UAVOS says that the parachute system is designed for UAS that can travel at speeds of up to 280 miles per hour, and that weigh up to 110 pounds.

“In the aircraft safety developments, saving an entire aircraft through a deployable parachute system is a crucial thing,” says Aliaksei Stratsilatau, CEO and lead developer of UAVOS.

“These trials have generated an amount of data which allows us to quantify the performance of parachute system for future missions. 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.”

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 the UAS being dragged along the ground.

Unfastening is carried out by the lock of a three-step release. During the first stage, the pilot chute is opened. During the second stage, the main chute is opened. During the third and final stage, the group of lines of the main parachute is released.
