EXPANDED RESIN CUFFS FOR MODIFYING INBOARD SECTIONS OF HIGH SPEED MODEL PROPELLER TEST BLADES

摘要

A method of applying expanded resin cuffs to model propeller blades for use in aerodynamic test programs on the USAF propeller dynamometer in the Cornell Aeronautical Laboratory Variable Density Wind Tunnel is presented.nIn addition to the method of application, a brief resume of the proof testing of the cuff material is presented.nNo attempt has been made to competitively evaluate the commer¬cial products used in fabrication of the cuffs. It should not be construed that the commercial products or trade names included in the report are the only products satisfactory for cuffs of this type.
