FLIR Systems has developed an improved propulsion system for its R80D SkyRaider Group 1 vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) that also increases the aircraft’s payload capacity and endurance.
Mark Holden, FLIR unmanned and integrated systems director of product strategy for the United States government, told Janes on 7 October during the Association for Unmanned Vehicle Systems International (AUVSI) Xponential trade show that this new propulsion system is plug and play. Current SkyRaider operators can simply remove the aircraft’s arms that house the standard motors and propellers, and replace them with new arms that house the improved propulsion system.

FLIR, Holden said, used a more robust motor in this improved propulsion system to better withstand sand and water ingress. This will enable the SkyRaider to operate better in sand and maritime environments.
The improved propulsion system increases the SkyRaider’s payload capacity from 2 kg to 3.5 kg. Holden told Janes on 6 October that FLIR, with the improved propulsion system, was able to increase the SkyRaider’s payload capacity while retaining the aircraft’s weight.
While the SkyRaider in its packed configuration remains roughly the same, Holden said the propellers with the new propulsion system grew from 47 cm in diameter to 54.6 cm in the standard propulsion system. The aircraft, including airframe, legs, four batteries, and no payload, weighs 4.5 kg. The standard pack of aircraft, base station, and HDZoom 30 payload weighs 8.5 kg.
