| Dual SWB-35 turbines in the NSCU/Navy NAV-AIR F-18 project |
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.
