A FEASIBILITY STUDY ON THE MEASUREMENT OF THE TIME-DEPENDENT SHROUDD PRESSURE OF A DUCTED PROPELLER

1961

HOUGH, GARY R.

Results of a limited study on the measurement of the instantaneous incremental shroud pressure on a ducted propeller by means of a piezoelectric transducer are given. The instrumentation is described and photographs of the observed pressure pattern presented. The feasibility of such measurements, the reproducibility and quality of the signal, and the magnitude and decay of the higher harmonics over a range of advance ratios are examined.
