General description

T-131B WIND TUNNEL

T-131B is a high-speed wind tunnel of a cyclic operation type with open loop and open-type test section. The T-131B is equipped with a four-stage ejector, a gas-flame air-heater and flow oxygen enrichment. Is also equipped with TV and photo cameras, the optical Toepler device for flow visualization, the gauging equipment for pressure, temperature, heat flow and flow rate; the six-component strain gauge balance, the high-efficiency computer system for the data acquisition and processing.

T-131V AERODYNAMIC TEST BENCH

T-131V Aerodynamic Test Bench is intended to investigate the operation processes in high speed jet engines combustion chambers. The tests are performed by the method of adjoined air ducting with gas-flame fore-heating and flow oxygen enrichment. The Test Bench is equipped with measuring system, instrumentation and gauging equipment for pressure, temperature and heat flow, gas and liquid consumption, optical Toepler device for flow visualization, TV and photo cameras and rapid videorecording system, thermal IR imager, thermal near-IR imager. The tests are performed when using the optical diagnosis techniques (emission spectroscopy, laser absorption spectroscopy, laser cutter and laser induced fluorescence).
