Reduction of torque pulsation in ultralight helicopter transmission
(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 ... -
REDUCTION OF UNCERTAINTIES IN LASER STRIPE MEASUREMENT OF SOLID PARTICLES CONCENTRATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Laser stripe measurement (LSM) is a relatively novel method for measuring a local concentration of coarse particles in a mixture with fluid. It is based on an analysis of camera records of the laser sheet penetration in ... -
