T-107 Wind Tunnel is an atmospheric continuous operation closed-loop facility that is equipped with four-component electro-mechanical balance to measure the aerodynamic forces and moments that affect the model. The WT is assigned to research (by use of specialized fan testing device) the high-speed fans, aircraft models and their components aerodynamic characteristics.
T-107 WT provides the following experimental studies to be carried out:
- The only test-bench in TsAGI assigned to test the high-speed fans (bi-rotary ones including) at cruising flight.
- Low test-costs due to lower drive power and air-cooling.
- Low level of flow initial vorticity.
- Application of band suspension enables the minimal model geometry distortion.
It is in T-107 WT where propulsions for such aircraft as Tu-95, An-22, An-70 and so on were enhanced. The total amount of cruising flight regimes tests within DREAM European FP7 was carried out in this WT. The thrust and moment characteristics of high-speed bi-rotary fans, the blades loads, blades strain, distribution of blade pressure, near-field blade noise and engine pylon influence were investigated. The helicopters profiles characteristics were studied.
