Full-Span Tiltrotor Aeroacoustic Model "FS TRAM" Overview and Initial Testing

Abstract

The Full-Span Tiltrotor Aeroacoustic Model "FS TRAM" is a dual-rotor, powered wind tunnel model with extensive instrumentation for measurement of structural and aerodynamic loads. The model has been developed to investigate tiltrotor aeromechanics and to generate a comprehensive database for validating analyses, as well as a research platform for studying current and future tiltrotor designs. This paper describes the Full-Span TRAM test stand and the first set of data obtained at the NASA Ames Research Center 40- by 80-Foot Wind Tunnel test conducted in late 2000. Limited results are presented and recommendations for future testing are provided. This model has been established as a valuable national asset for tiltrotor research.
