Energy Technologies & Resource Saving| Резюме: | The results of the comparative researches of given and new profiles are offered. The new profile is received on the basis of inverse problem solving which allows to get aerodynamic loss minimization and necessary index of rotor blade’s resistance in the zone with serving wires. The results are examined from the gas dynamics improvement of this zone of rotor blade in the area of transonic velocities point of view. It is shown that in this area new profile has a noticeably smaller loss profile coefficient than the given one which is used in real blade. |
