About this book
NASA Technical Reports Server (NTRS) 19930091376: Full-Scale Wind-Tunnel Tests of a Series of Metal Propellers on a VE-7 Airplane
Author: NASA Technical Reports Server (NTRS)
Year: 1929
An adjustable blade metal propeller was tested at five different angle settings, forming a series varying in pitch. The propeller was mounted on a VE-7 airplane in the twenty-foot propeller research tunnel of the National Advisory Committee for Aeronautics. The efficiencies were found to be from 4 to 7 per cent higher than those of standard wood propellers operating under the same conditions. The results are given in convenient form for use in selecting propellers for aircraft.
