T-106 is a close-layout, continuous-operation, variable-density wind tunnel designed for investigating aerodynamic characteristics of aircraft models and flight vehicle components at subsonic and transonic velocities. The flow is generated by a compressor with an electric drive of 32 MW.
Test section with a circular cross-section and perforated walls is equipped with an electric-mechanical balance and a set of in-model strain-gauge balances for measuring aerodynamic forces and moments of models and their elements, and with supporting devices of 3 types (strip suspension, tail sting and under-fuselage strut).
The wind tunnel is equipped with automated computation and measurement complex for data monitoring, registration, acquisition, and processing during the experiment.
- electric-mechanical and strain-gauge balance measurements of total aerodynamic characteristics of aircraft models and their elements;
- measurement of pressure distribution along the model surface using electronic pressure modules for 1000 points;
- determination of characteristics of inlet models and aircraft models with the flow passing through the internal channels of thenacelles;
- investigation of the models with simulation of the high-pressure jets (power plant nozzles, including those of variable thrust vector,jet flaps, etc.;
- investigation of characteristics of aircraft models static and dynamic aeroelasticity;
- test of half-models on a special supporting device;
- investigation of wing profiles;
- physical investigations.
During 70 years T-106 has been one of the most loaded TsAGI’s facilities for investigating different-application flight vehicles at high subsonic and transonic velocities.
