Ekolot ZEUS Drone Completes First Flights: VTOL & CTOL Capabilities Demonstrated

Poland has completed initial test flights of the ZEUS unmanned aerial vehicle (UAV), a new platform designed for both vertical take-off and landing (VTOL) and conventional take-off and landing (CTOL) operations. The flights, conducted by Ekolot Aerospace & Defense (EAD), demonstrated stable flight and autonomous capabilities in a CTOL configuration, according to EPKR Spotters.

The ZEUS platform is the result of collaboration between Poland-based EAD and Spanish firm UAV Navigation-Grupo Oesía. UAV Navigation-Grupo Oesía integrated its flight control systems into the ZEUS, providing guidance, navigation, and control functionalities. The system is designed to address operational requirements where traditional runways are unavailable, offering a versatile solution for a range of missions.

During the initial tests, controlled by Kuba Krukierek, the ZEUS UAV successfully took off in CTOL mode, achieved a stable altitude, and maintained precise flight control. A subsequent automated flight, the first of its size at EPKR, was also completed, EPKR Spotters reported.

The ZEUS family of aircraft encompasses varying configurations, with maximum take-off weights ranging from 100 to 250 kilograms for VTOL variants and up to 350 kilograms for CTOL versions. A modular design allows for adaptation with either VTOL or CTOL conversion kits, utilizing a single base airframe. Payload capacity varies accordingly, from 30 to 120 kilograms for VTOL models and up to 150 kilograms for the CTOL ZEUS G configuration.

The ZEUS G configuration is specifically engineered for long-endurance missions, capable of sustaining flight for 12 to 24 hours depending on payload and operational parameters. This capability is enhanced by advanced autopilot systems from UAV Navigation-Grupo Oesía, which include guidance, navigation, and control functions. The system is designed to function effectively even in environments where satellite navigation signals are degraded or unavailable, employing high-precision inertial navigation and a visual navigation system.

UAV Navigation-Grupo Oesía highlighted the importance of this capability in modern conflict scenarios, where electronic warfare tactics can disrupt or deny access to Global Navigation Satellite Systems (GNSS), potentially impacting the performance of UAVs reliant on satellite signals. The company stated that the ZEUS platform is designed to mitigate these risks.

The development of the ZEUS platform emphasizes modularity and adaptability, aiming to reduce development timelines and streamline logistics by utilizing a common airframe for diverse mission types.
