  • Reduction of torque pulsation in ultralight helicopter transmission 

    Autor: Dudnik, Vitaly
    (České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)
    Usually, 1–2 seats helicopters use piston engines. One of their disadvantages is a significant torque pulsation on the engine shaft. The main reason for such fluctuations is the change in parameters during the engine’s ...
