Full-Scale S-76 Rotor Performance and Loads at Low Speeds in the NASA Ames 80- by 120-Foot Wind Tunnel. Volume 2.
Abstract
Detailed dynamic loads data are divided into two sections; thrust sweep data and speed sweep data. Data for both forward flight thrust sweep conditions and speed sweep conditions with minimized flapping trim are presented in tabulated form in this appendix. Thrust sweep data runs are grouped in terms of increasing rotor advance ratio and shaft angle-of-attack, os. Speed sweep data runs are grouped in terms of increasing shaft angle-of-attack, a5, and thrust condition. For each of the measurements, the time-averaged mean, root-mean-square, one-half peak-to-peak value (absolute maximum minus the absolute minimum divided by 2), and the first twenty harmonics expressed in terms of Cosine and Sine components are presented. Definitions of the measurements that are presented in this section are shown below. Identification of test conditions and its location within this appendix are presented following these definitions.
