 The SWB-35 micro-turbine was SWB’s first production engine. This turbine has proven to be an extremely reliable power plant and has flown repeatedly in such projects as LoFLYTE and NSCU/Navy  NAV-AIR F-18 among others.  This turbine has been extensively tested in our test cell using the ASME 19.1 industry standard turbine testing procedures.  With the AMA's new rule limiting model turbine thrust at 35 pounds, we are now making the SWB-35 available to modelers for large scale jets.  The SWB-35 comes complete with state of the art electronic engine control package and starting equipment.  Call today to place an order.

 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.

 SWB Turbines would like for you to experience their newest turbojet engine developed and tailored specifically to turbine aero modelers, Measuring a mere 3.5 inches in diameter, this engine produces 11 pounds of screaming thrust and weighs just over 1 ½ pounds!!! Originally designed to produce 14 pounds of thrust, the Mamba was derated to 11 pounds to achieve its low fuel consumption, high reliability, and long life. The Mamba was designed to perfectly suit smaller 60-size ducted fan aircraft. The Mamba turbojets come ready to fly, ready to install in your model jet. If you are interested in the Mamba for your model, just call us at 920-725-3721, or email us: @ swbtubines.tds
