Figure 7: (a): Isentropic Mach Number contours at rotor tip calculated using a 3D viscous analysis of the data for stage 1 and stage 2 rotors for the forward swept configuration (GESFAR) at design speed near peak efficiency, (b): Tip kulite data over rotor 1 at design speed at three throttle settings, (c): Tip kulite data over rotor 1 at 95% speed at three throttle settings and (d): Tip kulite data at 91% speed at three throttle settings.
