A COMPARISON OF DUCTED PROPELLER THEORY WITH BELL X-22A EXPERIMENTAL DATA
Abstract
For the forward flight regime, a limited comparison is made between theoretical predictions of duct pressure distributions and data obtained from one-third and full scale model tests of the X-22A ducted propeller unit. The theoretical calculations are based upon previous studies of ducted propellers with finite blade number. It is found that the theory is in reasonable agreement with experiment and generally tends to underestimate the measured pressures. Also, the characteristic shape of the predicted distribution agrees well with the measured distribution.
