Characteristics of eight airfoils at speeds of 0.5-1.08 times speed of sound have been determined in open-jet air stream 2 in. in diam., using models of 1-in. chord; section of blades of propellers intended for use at high tip speeds should be of circular-arc form for outer part of blade and should be changed gradually to R. A. F. or Clark Y form as hub is approached.
