PROPELLER STATIC PERFORMANCE TESTS FOR V/STOL AIRCRAFT. PART 1. SUMMARY REPORT

Abstract

The tests were made because of a static performance thrust deficiency encountered during flight tests of the XC-142A V/STOL cargo aircraft. Twenty- eight versions of propellers were tested. Parameters studied during the tests included blade cuff (on or off), tip shape, twist, activity factor, camber, and airfoil section. Reduced data are presented in the form of performance coefficients and various tip Mach numbers for each configuration tested. Data on several other VTOL static thrust propellers are presented for additional information although they were not a part of this test series. Complete blade characteristic charts describing the physical characteristics of each blade tested provide a means of comparing the distribution of twist, thickness, chord, and camber against blade redial location for any given blade.
