IN-FLIGHT MEASUREMENT OF ROTOR BLADE AIRLOADS, BENDING MOMENTS, AND MOTIONS, TOGETHER WITH ROTOR SHAFT LOADS AND FUSELAGE VIBRATION, ON A TANDEM ROTOR HELICOPTER. VOLUME 1. INSTRUMENTATION AND IN-FLIGHT RECORDING SYSTEM

Abstract

An extensively instrumented tandem rotor helicopter was developed to measure the rotor blade airloads and the resulting rotor blade motions and bending moments, rotor shaft loads and moments, and fuselage vibration. The report details the design, assembly, and testing of the instrumentation system and documents the capability of the system for fulfilling the requirements of the program. The selection and testing of the system components are described in detail, along with the integration of these components into the overall instrumentation and recording system. The exhaustive tests of the system, both on the ground and in flight, are described in step-by-step sequence. The capacities and capabilities of the system are delineated and illustrated. Four technical appendixes, giving precise engineering data and statistical records, are included in the report.
