The analysis of pressure in blades of the carrying screw of the helicopter is carried out at their various fastening to the cartridge. The accounts are executed at change of a mode of flight and influence atmospheric turbulence. Accounts with change hard and mass characteristics of the blade also were carried out, by the joint decision of the equations of fluctuations of the blade and equations of balancing of the helicopter. On the basis of the carried out accounts the parameters are established, which influence is most essential, that has allowed to formulate the recommendations for reduction of a level of variable pressure in blades of the carrying screw.
