The proposed corrected method of conversion of gas-dynamic characteristics of high-pressure stage of turbocharger
operating in the area of high circumferential speeds (conditional Mach numbers > 0,5) to other rotor speeds is given
in the work, taking into account deviation from kinematic and dynamic similarity conditions. The method of combined
control due to creation of swirling of flow in front of impeller and simultaneous change of rotation speed is considered.
Analysis of experimental and theoretical results is done.
