Acoustic tests of MS-21 wing panels completed at TsAGI

25 July 2012

Specialists from the electrical and electromechanical units and the Aircraft and Rocket Aerodynamics department at TsAGI have carried out a range of activities for the commissioning and development for normal operation of a new power supply for the T-106 wind tunnel, installed following modernization in 

2010–2011.

The return of the T-106 to commercial use means the possibility of testing models with minimal distortion in the geometry of the runway configuration at high Reynolds numbers, as well as testing of models at transonic Mach numbers.

At present, specialists from the TsAGI Strength and Load Standards and Aircraft and Rocket Aerodynamics departments have begun the first cycle of industrial tests after the upgrade — flutter testing of a model console of the vertical tail of the future T-50 PAK-FA plane, for JSC Sukhoi.

The rejection of motor-generators due to work carried out in the T-106 wind tunnel, and the commissioning of thyristor converters can save energy and more efficiently prepare the wind tunnel for launches. An increase in the maximum power will make it possible not only to implement the entire operating range of T-106 wind tunnel modes, but also provide the possibility of future expansion, and improved accuracy to maintain the flow rate. The modernization required the equipping of the engine room with water cooling systems, air ventilation and climate control, operated from an automated workstation.

The T-106 wind tunnel is one of the most popular wind installations at TsAGI, used for the study of various aircraft types in a range of high subsonic and transonic speeds.
