Transonic Dynamics Tunnel (TDT) Facility
The Transonic Dynamics Tunnel (TDT) is a closed-circuit, continuous flow, variable pressure wind tunnel. The TDT is dedicated to identifying and solving aeroelasticity issues confronting fixed-wing aircraft and helicopter and tiltrotor configurations.

Characteristics
The Transonic Dynamics Tunnel (TDT) is a closed-circuit, continuous-flow, variable-pressure wind tunnel capable of using either air or R-134a as a test medium.
Quick Facts
Rotary-wing tests at the TDT have investigated performance, loads, and stability characteristics, while fixed-wing flutter, buffet, and divergence have been scrutinized as well.
Data Acquisition
Particularly useful for flutter tests is a group of four bypass valves that connect the TDT test section area to the opposite leg of the wind tunnel circuit downstream of the fan motor.
