Description

The SP-275 TS ROS from Sky Power International is a powerful two-cylinder two-stroke Boxer engine with a displacement of 275 cm³. Developed for use in unmanned aerial vehicles (UAVs), this engine offers an ideal combination of power, reliability and efficiency. With a maximum power output of 21.7 hp (16.0 kW) at 6000 rpm, the SP-275 TS ROS is the largest and most powerful two-cylinder engine in the Sky Power International portfolio. It is particularly suitable for UAVs with a maximum take-off weight (MTOW) between 100 and 150 kg.

Sky Power places a strong emphasis on customer support and provides comprehensive services to ensure that the SP-275 TS ROS meets individual requirements. With state-of-the-art technology and continuous development, Sky Power ensures that its Boxer engines meet the highest standards in the UAV industry. The SP-275 TS ROS is therefore the ideal choice for operators looking for a reliable, powerful and versatile engine for demanding applications.

The dual ignition ensures increased operational reliability, while the rear output shaft enables versatile integration options in various applications. The light weight engine is compact yet powerful. The optimized oil-fuel mixture ratio of 1:50 guarantees clean combustion and a long service life. Thanks to its wide speed range of 1500 to 10,000 rpm, the SP-275 TS ROS is suitable for both long-haul flights and highly dynamic missions.

This engine type has been successfully produced for over a decade and has completed more than 10,000 operating hours. Stringent testing procedures, including over 800 hours on the test stand with a wide range of mission profiles, guarantee maximum reliability. With over 1,000 units produced, the engine is widely used in a variety of climatic conditions, from extreme cold to high humidity, salty air and dusty environments. Many operators use the SP-275 TS ROS for long-range flights, including beyond visual line of sight (BVLOS) missions.

A key feature of the SP-275 TS ROS is the optional integration of a starter generator on the rear output shaft. This function not only allows the engine to be started electrically, but also to generate power during operation. This is particularly advantageous for UAVs with increased energy requirements, for example, due to on-board electronics or communication systems. The robust construction and the use of high-quality materials ensure a long service life and reliable operation even under demanding conditions.

For environmentally conscious operators, Sky Power offers the option of using pre-mixed Aspen 2-stroke fuel. This fuel ensures clean combustion, reduces deposits in the engine and extends maintenance intervals. In addition, Sky Power offers a wide range of accessories, including specific tools such as the propeller drilling template, which facilitates precise installation and maintenance of the engine.
