Sky Power and Cavok UAS Announce Strategic Partnership for European Long Endurance VTOL Convertible UAV

Sky Power GmbH, renowned as a leading manufacturer of cutting-edge 2-stroke combustion and Wankel engines for unmanned aerial systems (UAS) with an MTOW range of 25 to 120kg, is making waves in the drone industry. The company’s propulsion portfolio encompasses a comprehensive lineup, including TRL9 fuel injection, carburetor, hybrid, and heavy fuel engine systems. Setting the bar high for innovation and performance, Sky Power proudly manufactures all engines in Germany using state-of-the-art technology.

Adding to this exciting development, Cavok UAS, a premier professional drone manufacturer based in France, has carved its niche in the market with an impressive range of electrical and internal combustion drones designed for security, logistics, and industrial applications, boasting MTOW capacities between 2 and 1360kg.

This dynamic partnership is rooted in the shared vision of producing European-made drones, ensuring the delivery of cutting-edge solutions within the continent. Cavok UAS has handpicked Sky Power’s SP-110 FI TS propulsion system to equip their CK50 VTOL convertible UAV. Thanks to the remarkable performance of the SP-110 FI TS engine, the CK50 showcases an impressive flight endurance of over 10.5 hours, leveraging the full potential of CK50’s high efficiency design.

“This collaboration between Cavok UAS and Sky Power is a critical milestone in the European UAV production landscape,” stated the CEO of Cavok UAS. “In times of uncertainty, where supply chains and production capacities face challenges due to pandemics or conflicts, our alliance with European producers becomes a key success factor for institutional clients who demand regional production for strategic equipment delivery, technical support, and MRO services.”

Beyond the origin of components, the success of this venture relies on perfect harmony between performance, reliability, and interfaces, ensuring seamless integration of cutting-edge technology for the benefit of end-users. With a shared commitment to flight safety, Cavok UAS values the close technical collaboration between their teams and the availability of crucial information from SP-110 FI TS engine parameters.
