Correlation of Ah-1g Airframe Flight Vibration Data with a Coupled Rotor-Fuselage Analysis
Author: National Aeronautics and Space Administration (NASA)
Publisher: Createspace Independent Publishing Platform
ISBN: 9781723548345
Category :
Languages : en
Pages : 228
Book Description
The formulation and features of the Rotor-Airframe Comprehensive Analysis Program (RACAP) is described. The analysis employs a frequency domain, transfer matrix approach for the blade structural model, a time domain wake or momentum theory aerodynamic model, and impedance matching for rotor-fuselage coupling. The analysis is applied to the AH-1G helicopter, and a correlation study is conducted on fuselage vibration predictions. The purpose of the study is to evaluate the state-of-the-art in helicopter fuselage vibration prediction technology. The fuselage vibration predicted using RACAP are fairly good in the vertical direction and somewhat deficient in the lateral/longitudinal directions. Some of these deficiencies are traced to the fuselage finite element model. Sangha, K. and Shamie, J. Unspecified Center NASA-CR-181974, NAS 1.26:181974 NAS1-17498; RTOP 505-63-51-01...
