HELICOPTER MAIN ROTOR BLADE TRACKING DEVICE

摘要

This report has been prepared by the Systems Management and Engineering Department, Fairchild Camera and Instrument Corporation, to describe the design, development and testing of a Helicopter Main Rotor Blade Tracking Device, as specified in Navy Contract NONR-1767(00). In its final configuration, Device 9U96 consisted of a hand-held viewer and its attendant power supply and five corner cube wing tip reflectors of different colors. The Device was used to measure the out-of-track of the Main Rotor Blades of an H-37B aircraft. It was found that Device 9U96 was capable of measuring individual out-of-track to less than 1/4 of an inch at the blade cap at night. Testing during the day revealed that the Device did not have full 24-hour capability.
