GöKHUN Unmanned Aerial System Takes Off Powered by Sky Power’s SP 210 FI GS Engine

The GöKHUN Unmanned Aerial System (UAS), developed by Turkish manufacturer ESEN, is a tactical VTOL drone designed for operational flexibility without requiring a runway. Powered by the modern SP 210 FI GS 2-stroke engine from Sky Power International, the GöKHUN UAS delivers superior performance for intelligence, surveillance, and reconnaissance (ISR) missions on land and sea.

Key Features of the GöKHUN UAS

• Vertical Take-Off and Landing (VTOL): Can take off and land in a compact 10×10 meter area, enabling deployment in challenging terrains and aboard ships without infrastructure.

• Weight and Payload: Maximum take-off weight of 110 kg, with up to 26 kg fuel and payload capacity.

• Flight Endurance: Up to 16 hours of flight time with minimum payload; approximately 9 hours with a 12 kg sensor load.

• Speed and Range: Cruising speeds between 96 and 158 km/h with a direct line-of-sight range exceeding 150 km.

• Service Ceiling: Operational altitude of around 5,500 meters.

• Dual Payload Capability: Supports simultaneous operation of two different payloads, such as EO/IR sensors for day and night or communication and reconnaissance systems.

Advanced Engine Technology by Sky Power International

The GöKHUN’s propulsion system features the SP 210 FI GS, a two-cylinder 210 cc 2-stroke engine delivering 11 kW (14.9 hp) at 5,500 rpm. This engine is specifically designed for tactical drones with take-off weights between 60 and 100 kg.

• Robust and Compact: Weighs only 9.4 kg and includes integrated twin spark ignition, ECU, fuel pump, sensors, preheating system, starter generator, and stainless-steel exhaust.

• Fuel Efficiency: Electronic fuel injection (EFI) ensures precise engine management for reduced fuel consumption and emissions.

• Reliability: Redundant ignition and power supply with 12–15 V DC output supports sensor integration and onboard communication.

• Environmental Adaptability: Engine performance optimized for harsh conditions, from dry deserts to humid maritime environments.

Karsten Schudt, Managing Director of Sky Power International GmbH, notes:

“The modular engine design, long mission endurance, and redundant safety features perfectly complement the GöKHUN platform, delivering a state-of-the-art ISR solution for demanding operational environments.”

Versatile Applications and Robust Safety Features

The GöKHUN UAS excels in ISR applications but is equally suited for environmental monitoring, disaster relief, border surveillance, anti-smuggling, and precision agriculture. Key system features include:

• GNSS-Independent Navigation: Integrated vision-based GöRDES navigation allows operation in GPS-denied environments.

• Redundant Systems: Double or triple redundancy in navigation, flight control, data transmission, and power supply ensures mission safety.

• Autonomous Return: UAV automatically returns to the launch point if communication is lost.

• Electronic Interference Protection: GNSS interference protection maintains operation integrity in electronic warfare conditions.

• Rapid Deployment: Two technicians can prepare the system for operation in approximately 15 minutes; transportable in two standard vehicles.

• Modular and Maintainable: Easy payload swaps and system maintenance support various mission profiles.

Compliance and Integration

• ITAR-free design facilitates international export.

• NATO standards compliance (AEP-83/84) ensures seamless integration with existing tactical networks.

• Operating temperature range from −30°C to +55°C and stability in winds up to 40 knots underline operational robustness.
