The SP-55 TS ROS from Sky Power International is an advanced single-cylinder two-stroke engine designed specifically for use in unmanned aerial vehicles (UAVs). With a displacement of 55 cm³ and an output of 3.9 hp (2.9 kW) at 6500 rpm, the engine offers an optimal combination of power and efficiency. The compact design with a rear output shaft allows the engine to be fitted with a generator, making it suitable for various UAV types, such as fixed-wing aircraft, helicopters and VTOL aircraft. This versatility makes the SP-55 TS ROS an excellent choice for demanding applications in the UAV industry.

The SP-55 TS ROS is an excellent solution for UAV operators looking for a reliable, powerful and flexible engine. Its advanced technology and customization options make it ideal for demanding applications, significantly contributing to the efficiency, reliability and performance of modern unmanned aerial vehicles.

The engine design features numerous innovative characteristics. Two spark plugs per cylinder ensure increased reliability and efficiency. The CNC-milled crankcase allows for customization, enabling the engine to meet the specific requirements of different UAV platforms. The SP-55 TS ROS operates in a wide speed range from 2200 to 10,000 RPM, making it ideal for a variety of flight conditions and mission profiles. Weighing only 2.58 kg including the ignition, the engine helps maximize payload capacity while increasing the overall efficiency of the UAV.

The operating voltage of 6 to 8.4 V DC makes the SP-55 TS ROS compatible with most UAV on-board power systems, facilitating integration into existing platforms. Robust construction ensures high reliability and durability, even under demanding operating conditions. Particularly outstanding is the engine’s ability to generate additional power through the optional integration of a generator on the rear output shaft. This feature is especially advantageous in hybrid UAV configurations where an additional power supply is needed.
