Wind-tunnel Tests of Single- and Dual-rotating Tractor Propellers of Large Blade Width

J. D. Maynard

Abstract

Report presenting tests of 10-foot diameter, single- and dual-rotating tractor propellers with two to eight blades conducted in the 20-foot propeller-research tunnel. The blades were 50 percent wider than those used in previous investigations. Results regarding the effect of dual rotation and effect of solidity are provided.
