Performance and Acoustic Testing of a Variable Camber Propeller

The report presents the test results obtained from a series of performance and acoustic near-field measurements on a propeller fitted with a variable camber feature. The subject propeller effects a change in camber by deflecting a flap positioned along the 72% chordal line of each blade. The tests w...

Description
Summary:The report presents the test results obtained from a series of performance and acoustic near-field measurements on a propeller fitted with a variable camber feature. The subject propeller effects a change in camber by deflecting a flap positioned along the 72% chordal line of each blade. The tests were conducted on a 10,000 horsepower electric whirl rig. The tests represent the only test data available on this unique propeller configuration which is considered to have good potential for V/STOL applications.
