JetCat SPH5 twin-shaft helicopter engines
The operation of the SPH engines is analogous to the SPT engines, but instead of a planetary gear, a 90 degree bevel gear is mounted, which drives in the normal case in a directly mounted centrifugal clutch. A Hall sensor measures the transmission output speed. The respective gear ratios are freely programmable in the ECU (gear output to main rotor, main rotor to tail rotor). The user can thus directly program the desired main rotor speed, the rest is done by the software of the ECU. The JetCat SPH engines are preferably used in helicopters. An ECU software specially developed for this application allows the free programming of up to three main rotor speeds, which can then be switched on the transmitter side via a 3-position switch.
