Model Rotor Test Data for Verification of Blade Response and Rotor Performance Calculations

Abstract

Dynamically scaled model helicopter rotor tests were carried out to collect data for the verification and improvement of helicopter rotor and blade response calculations. Four fully articulated model rotor blade configurations were fabricated and tested. The configurations included variation in built-in twist, airfoil camber, and stiffness. The dynamically scaled configurations were based on H-34 rotor blades previously tested at full scale. The complete body of rotor performance and blade response time history data is preserved in digital form on magnetic tapes. A computer program to sample the data tapes and perform the most common types of processing is also available.
