XV-5A AERODYNAMIC-PROPULSION DATA CORRELATION AND CHARACTERISTICS DEVELOPMENT BASED ON WIND TUNNEL CHARACTERISTICS

William C. Parks, Swingle, Robert L., William A. Swope

Abstract

The report presents the results of efforts to correlate data for the XV-5A V/STOL aircraft configuration, including small-scale and full-scale wind tunnel investigations and wind tunnel and thrust stand tests of the actual aircraft. The majority of the data correlation work was performed utilizing results from 1/6-scale and full-scale model tests which were conducted during the period of aircraft development. Correlation was limited primarily to wing- body characteristics. Corrections for configuration differences were developed, and the effects of dynamic dissimilarity of the fan systems were evaluated in the data comparison effort. Wind tunnel wall corrections were applied to the full-scale data.
