CALCULATION OF LOADS ON THE CONTROLS WITH HELICOPTER MAIN ROTOR OF SINGLE-ROTOR DESIGN
Published 2016-11-01“…On the basis of the hinge moments values data loads on rotorcraft rotating ring, arising at different azimuthal location of the rotating main rotor blades are calculated.The calculations executed on the example of Mi-34 helicopter main rotor have shown that average loads in one revolution in the channel of collective pitch control increase in a control path at flying speed. At the same time loads in the channel of longitudinal control make up to 80 % of loads in the channel of collective pitch control, and in the channel oflateral control - to 40 % that will well be coordinated with the provided data of flight tests.…”
