This paper introduces the Tilt Rotor Aeroacoustic Model 'TRAM' project. The TRAM project is a key infrastructure investment for NASA and U.S. Army tiltrotor research. The TRAM project consists of the development and testing of two modular, hardware-compatible, test stands: an isolated rotor configuration and a full-span model 'dual rotors with a complete airframe representation'. These two test stands are inclusively called the Tilt Rotor Aeroacoustic Model 'TRAM'. The baseline proprotors and airframe of the TRAM test stands are nominally 1/4-scale representations of the V-22 Osprey aircraft. The research objectives of the project, the TRAM hardware design features and capabilities required to meet those objectives, and the status of the project are discussed in detail in this paper.
