Losses in the transonic mode are primarily caused by shock-induced separation on the suction side of the rear blade.
The study shows a significant increase in shock losses at higher Mach numbers in the high-speed windmilling mode.
Shock interactions at the leading edge impact the airflow angle, affecting boundary layer losses on the rear blade.
Under supersonic conditions, a re-laminarization phenomenon occurs on the suction side of the rear blade.
