ASPECTS REGARDING THE KINEMATIC ANALYSIS OF POWER TRANSMISSION FROM HELICOPTER DESIGN

Abstract

The main power transmission of helicopters is a complex technical system, which fulfills its functional role of transforming the kinematic parameters from the turboshaft into the kinematic parameters necessary for the optimal operation of the main rotor of the helicopter. The paper presents a method of kinematic analysis of the power transmission for the main rotor and the anti-torque rotor of a helicopter. Based on the kinematic diagram of this mechanical transmission, the angular velocities and the transmission ratios achieved by the double-planetary gearbox of the main and the secondary transmission are determined.
