Jetcat SPH 5 Heli Turbine

JETCAT SPH

JetCat SPH Two-Shaft Helicopter Engines

The function of the SPH engines is similar to the SPT engines, but instead of a planetary gear a 90 degree angular gear is mounted, which normally drives a directly mounted centrifugal clutch. A Hall sensor measures the gearbox output speed. The respective transmission ratios are freely programmable in the ECU (gear output to main rotor, main rotor to tail rotor). The user can program the desired main rotor speed directly, the rest is done by the ECU software. 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 by means of a 3-step switch. The electronic control of both shafts ensures that the rotor speed is kept constant even during load changes.
