JetCat SPH 5 Helicopter turbine

Jet-Cat SPH 5H Heli turbine

This 2 Axles turbine is special designed for use in a helicopter.

The functioning of the SPH is analogous to the SPT engines, but is instead a planetary gear a 90 degree Angle gearbox mounted, which collects in the normal case in a direct-mounted centrifugal clutch. A Hall sensor measures the Gearbox output speed. The respective ratios are freely programmable in the ECU (gearbox output to Main rotor, tail rotor main rotor). The user can program directly the desired main rotor speed, the software of the ECU will do the rest. The JetCat SPH used preferably in the field of helicopter engines. One specifically for this case developed ECU software allows free programming of up to three main rotor speeds, which then transmitter via 3-position switch are reversible. The electronic control of both waves will make sure that the rotor speed is kept constant even with load change.
