GALAXY GRS s.r.o. GBS 10/650 Speedy UAV

The GBS 10/650 Speedy UAV from GALAXY GRS (Czech Republic) is the high-speed variant of the GBS 10/650 ballistic recovery unit for fast UAVs of 35 to 65 kg, such as occur among fixed-wing aircraft and VTOL configurations. A pyrogenerator ejects the canopy. The unit measures 130 mm in diameter and 250 mm in length.

The rated value is the upper limit of 65 kg take-off weight. The system weighs 1,500 g. Motor cut-off (FTS) is optional: a motor disconnector is available as additional equipment, and in the test the electronics switched the motors off automatically on deployment. At masses of 35 to 65 kg and high flight speed, a lot of energy sits in the motion: the opening needs distance and time, and the impact energy grows with the mass and with the square of the sink rate. Minimum deployment altitude and opening speed are to be taken from the manufacturer's data sheet for the real mass.

Aircraft above 25 kg lie outside the EU classes C0 to C6 and the Open category; they are operated in the Specific category with a risk assessment (SORA) and an operational authorisation, or certified. In the test, release was by an impulse from the pilot. The manufacturer names environmental testing to RTCA DO-160G. Evidence to ASTM F3322 or EASA MoC Light-UAS.2511 and 2512 may be required for flights over people and applies only to the tested combination of system and aircraft.

The pyrogenerator is replaced after a deployment; canopy and lines must be checked for tears, heat marks and moisture, above all after an opening at high speed. Pyrotechnic releases can fall under their own transport and storage rules; shipping and storage follow the manufacturer's instructions. Selection turns on take-off weight, cruise speed and the system weight of 1,500 g.
