The SWB-25 is an aerospace grade micro-turbine which was designed to meet the need for a powerful engine required for smaller size applications. Unlike other small aero-model turbines, this engine is specifically designed for professional UAV applications. It is longer lasting, has superior bearings, and a much lower fuel consumption. Originally designed for 30 pounds of thrust, the turbine has been de-rated to 25 pounds of thrust for extended service life. The original SWB-25 prototype was used repeatedly in the development of our electronic turbine control system. With over 3,000 runs on this turbine, the engine continues to run flawlessly. The SWB-25 comes complete with electronic engine control package and starting equipment.
