SKY POWER SP-275 FI TS Engine
SP-275 2-stroke dual cylinder with 275cc is the largest and most powerful dual cylinder, making it the most versatile 2 stroke engine in our portfolio. This power dense propulsion system is most suited to programs from 100-150kg MTOW due to its dimensions and power output. This engine size has been manufactured for over a decade and accrued more than 10,000 operational hours. Internal development and testing has accumulated over 800hrs on dynamometer simulating various mission profiles and conditions. With over 1000 engine systems produced to date, the robustness and durability of the SP-275 has been proven in all global scenarios, from extreme cold to heat, humid and salty conditions to dust.
Many customers fly over 12 hours continuously and BVLOS, due to this engines target market system. With the starter generator mounted on the ROS, the 3W SP-275 is a dynamic propulsion system capable of several different configurations
VERSIONS INCLUDE:
CR/TS VERSION (INCLUDING IGNITION AND AIR FILTER)
TS/ROS VERSION (INCLUDING IGNITION AND AIR FILTER)
FI/TS VERSION (IGNITION ECU & EXHAUST)
FI GEN VERSION (FI W/IGNITION ECU & EXHAUST)/FI OR EFI ONE KEY STARTER/GENERATOR WITH CONTROLLER
HF/FI/TS VERSION (HF, EFI/FI, ONE KEY STARTER/GENERATOR WITH CONTROLLER)
The SP-275 series is designed with twin spark plugs and can be equipped with a carburetor or a fuel injection. The generator is mounted on the rear output shaft. All engines, except SP-275 TS CR, are equipped with the ignition HKZ215 and the ECU030. The electronics of the HKZ215 can be installed on an additional system carrier which sits on top of the cylinders. The engine is available with or without system carrier.
A dedicated version, the SP-275 TS CR, is designed especially for target drone applications. This version has a rear carburetor and has a low-profile design optimized for high speed training flights requiring minimal aerodynamic cross section.
The HKZ215 is a high performance ignition system which achieves considerably higher ignition performance. Thereby the overall performance of the engine is increased and the exhaust emission values are improved.
The HKZ is installed in a light and robust, nickel-plated aluminium housing. All add-on components such as connection sockets, spark plug connectors are designed for demanding areas of application. The ignition system is shielded and only has low interference radiation.
The SP-275 TS CR is designed with twin spark plugs and manual decompression valves. The engine is very compact due to the rear carburetor.
