Measurements were obtained as great as 1100 and 900 fps respectively; results indicate that small effects on wake with increasing Mach number are primarily due to changes in rotorload distribution resulting from changes in Mach number rather than to compressibility effects on wake itself; no effect of tip Mach number on instantaneous velocities was observed.
