Abstract
The results of calculations aerodynamic characteristics a profile and blade tips helicopter rotor executed by a method of numerical modeling hydrodynamic processes (CFD) on supercomputer МАI are presented. Represents comparative testing of RANS turbulence models on the basis of calculation results aerodynamic characteristics profile NACA 230-12 and their comparisons with experiment. Represents results of calculations aerodynamic characteristics for four blade tips and comparison their with results of the experiments conducted on a models in wind tunnels МАI.Keywords:
model of turbulence RANS; aerodynamic characteristics; blade profile; blade tips of main helicopter rotor.Download
