Hybrid propulsion systems consisting of combustion and electric engines
Sky Power GmbH offers a wide range of innovative hybrid propulsion systems that have been specifically developed for use in unmanned aerial vehicles (UAVs). These systems combine the advantages of combustion engines and electric drives, enabling UAVs to achieve a greater range and longer flight times. The hybrid propulsion systems therefore represent a flexible and efficient solution that meets the requirements of a wide range of missions. Thanks to the combination of combustion and electric engine technology, these hybrid systems enable longer flight times, greater ranges and the ability to safely transport heavier payloads. Especially when transporting heavy loads, hybrid solutions provide safe and reliable engine performance, even under demanding operating conditions.
The hybrid propulsion systems consist of several key components that ensure optimum function and efficiency. A precise fuel injection system ensures accurate fuel delivery, which increases engine performance and reduces fuel consumption. The brushless DC generator efficiently converts mechanical energy into electrical energy to power the UAV’s electrical systems. The SGC 352 starter-generator controller, a lightweight and compact control unit, regulates both the engine starting process and the generation of electrical energy. The integrated HKZ ignition system improves ignition performance and thus contributes to increased engine performance and reduced emissions. An additional cooling system ensures effective temperature regulation of the engine and generator, which ensures reliable operation under different environmental conditions.
The hybrid engines are designed for efficiency and compactness. The engine is integrated into a robust aluminum frame, with injection, control unit, temperature regulation and air supply mounted on the side. The UAV generator is located on the rear output shaft, making the hybrid system particularly space-saving. The cooling system is located above the engine and generator, providing the necessary fresh air supply and dissipating hot air.
Sky Power offers various hybrid configurations to meet different requirements
SP-55 FI TS
The SP-55 FI TS is a 2-stroke-engine, which was specially developed for smaller UAVs and impresses with its compactness and efficiency.
SP-180 SRE hybrid
The SP-180 SRE hybrid, a powerful Wankel engine, is available for more power-intensive applications.
SP-180 HF SRE
Another variant is the SP-180 HF SRE, which has been optimized for operation with heavy fuel and is therefore ideal for ISR missions.
SP-180 SRE Hybrid Demonstrator
SP-180 SRE Hybrid Demonstrator provides a test solution for the SP-180. Due to the compact design the whole test stand is well suited for portable use.
