AbstractThe results of calculations aerodynamic characteristics main rotor helicopter on a hovering are presented. Calculations are executed by a method of numerical modeling hydrodynamic processes (CFD) on supercomputer МАИ. Comparison results of calculation with experiment are presented. The character of a current in a blade tip, form of a vortical trace, field of inductive speeds created by the main rotor helicopter are investigated. Analysis of influence blade tip geometry and anhedral angel for three blade tip types on rotor is executed.
Keywords:aerodynamic characteristics; blade tips of a main rotor helicopter; CFD methods.
