Study extends initial investigation (see Engineering Index 1956, p 56, under Aircraft Propellers -- Vibrations) to obtain information on oscillating pressures at various forward speeds, power, and engine speed; effects shown as comparisons of noise emitted from rectangular and tapered blade propellers with changes in operating parameters of Mach number, power, and engine speed.
