SWB-45
 |
 |
The SWB-35 which was originally developed for use in medium to large scale UAV applications has since been redesigned to produce 45 pounds of thrust as compared to the original 35 pounds of thrust. The new SWB-45 contains a new highly efficient compressor and redesigned diffuser, along with a re-matched turbine to increase overall performance and efficiency. The SWB-45 comes complete with electronic engine control package and starting equipment.
