Abstract

The 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.
