The SP-56 ROS is the smallest two-cylinder boxer engine in the Sky Power portfolio and is specifically designed for unmanned aerial vehicle systems (UAS). With a displacement of 56 cm³ and an output of 4.6 hp (3.4 kW) at 7,000 rpm, this two-stroke engine offers an impressive combination of power and size. The SP-56 ROS is characterized by its compact design and high thermal stability. The improved cylinder design ensures optimal heat dissipation, which means that the engine works reliably even under demanding conditions. The rear output shaft (ROS) enables the installation of a generator, which is particularly advantageous for applications with increased energy requirements.

The SP-56 ROS from Sky Power is an excellent choice for users looking for a powerful, reliable and versatile two-cylinder engine for their unmanned aerial vehicle systems. Its technical specifications, combined with its flexibility in terms of equipment and high manufacturing quality, make it a first-class solution for a wide range of applications in the UAS sector.

One outstanding feature of the SP-56 ROS is its low vibration level. Thanks to the boxer engine design, vibrations are minimized, which extends the engine’s service life and increases operational reliability. This feature is particularly important for UAS since stable and low-vibration engines are easier on the sensors and electronics on board. The engine is equipped with a standard carburetor but can be optionally upgraded with a starter generator and controller. This flexibility makes it possible to adapt the SP-56 ROS to different application scenarios and to meet the specific requirements of various UAS platforms.

The high-power density of the SP-56 ROS makes it ideal for use in small helicopter UAS and fixed-wing platforms. Its low weight and compact design help to keep the aircraft’s total weight low, which in turn improves flight time and maneuverability. Sky Power places a high value on quality and precision, which is why the SP-56 ROS is manufactured using the latest CNC technology to ensure the highest accuracy of fit and reliability. The use of high-quality materials and careful workmanship are reflected in the durability and performance of the engine.

Another advantage of the SP-56 ROS is its easy maintenance. The engine’s design allows quick access to all relevant components, making inspections and service work easier. This reduces downtime and increases the operational readiness of the UAS. For operators who value sustainability, the SP-56 ROS offers a more environmentally friendly option compared to other engines in its class due to its efficient fuel consumption. This not only results in lower operating costs, but also in a reduced environmental impact.
