US: Drone Rescue will launch its parachute systems DRS-5 and DRS-10 for the first time at Intergeo, at stand 12.0B.112 in Hall 12, Oct. 16-18.

Parachute rescue system DRS-5 is designed for multicopters with a total weight of up to 8 kg. The system consists of a carbon cage in which the parachute is stored, as well as the associated electronics.

The electronics, including the sensors, monitor the flight status of a drone independent of the flight controller. A sophisticated algorithm merges this sensor data, through which an automatic crash detection can be realized, the company said.

Also, the algorithm reacts faster than the pilot: the system ejects the parachute itself. All flight data and movements are recorded in a black box. In an emergency, these can be read out at the request of the customer and made available to insurance companies or authorities.

“Our goal is to ensure that even in an emergency beyond visual line of sight the drone can be safely intercepted. With our parachute system, that is always possible, due to the electronics that are completely separate and independent of the flight controller,” said Andreas Ploier, CEO and co-founder of Drone Rescue. “In addition, our system has the advantage that it manages completely without explosive, pyrotechnical solutions. Consequently, we have a system that is considerably lighter, and functions even in a worst-case scenario.”

In both cases, the DRS-5 was attached to the side of the main body of the drone. In each of the tests, the parachute was ejected at a height of 30 meters. Every test was documented.

Furthermore, the data were saved both in the flight controller as well as in the DRS-5 sensor system. After every 10th test, the parachute system was subjected to a visual examination and checked for possible damage or wear.

“After conclusion of the tests, it can be recorded that all 100 flights were successfully completed,” Ploier said. “In every test the multicopter landed safely. Thereby, the kinetic energy was significantly below the limit of 79 J. All requirements specified by the European Aviation Safety Agency (EASA) were observed.”

Besides the DRS-5, the structurally identical parachute system DRS-10, which is designed for multicopters with a total weight between 5 and 20 kg, will also be presented at  Intergeo 2018. “The DRS-10 system functions exactly the same as the DRS-5 and falls back on the same components. These are constructed identically, just oriented for a higher payload. The functioning method of both parachute systems is identical,” Ploier said.
