EXPERIMENTAL AERODYNAMICS

The TUSAS Large Sound Subwind Tunnel has been established to meet the critical experimental aerodynamic needs of aircraft in the development process.

Wind Tunnel model design, analysis, production, installation, instrumentation and wind tunnel tests are carried out. In this context, integrated solutions for wind tunnel test needs are offered. According to the requirements, an integrated solution can be provided with aerodynamic design, analysis and wind tunnel tests. Along with the defense and aviation sector, capabilities are available to meet the needs in areas such as automotive, energy and urbanism.

Within the scope of aerodynamics and test engineering; engineering services such as model wind load forecasts, wall effect corrections and prediction of critical flow conditions and test planning, execution and reporting are provided. An integrated engineering approach is adopted from pre-test optimization to result verification.

Wind tunnel test planning, test matrix optimization
Model wind load analysis
Simulation of wall effect corrections and critical test conditions
Integration of experimental/computational flow dynamics in the solution of design problems
Concept validation and creating a database for full flight

TUSAS Large Sound Under Wind Tunnel (TST) is a closed-loop atmospheric facility. In order to maintain the air temperature in the flow, the exchanger is equipped with flow-regulating curtains for flow regulation along with being available. Acoustic insulations are also available to reduce noise in the test hall and tunnel circuit. With three different test sections, Mach has a speed capacity of up to 0.55’. Thanks to the interchangeable test sections, there are different speed and scale alternatives according to the test demands. With different model support systems, it is also possible to test different air vehicles and areas.

A comprehensive infrastructure is offered with advanced sensor technologies and in-house designed measuring systems to ensure the proper precision and efficiency of the data collected from the tests.Integrated solutions from 6-component high-precision balances to pitot tubes that analyze flow dynamics, maximizes data reliability. All models; prepared in-house with instrumentation, calibration and data collection systems. The sensors used are listed below.

Inner Balances (6 component forces, moment)
accelerometers
Strain gauges
Pitot tubes
Unstable pressure sensors
Hot wire anemometers

Wind tunnel model design, analysis, production, assembly and instrumentation activities are carried out within TUSAS since 2019. From this date until today, all processes of the models used in the tests carried out in different wind tunnels for TUSAS products have been carried out by TUSAS. 5/9 axis precision CNC looms in the model production infrastructure established within the tunnel and model production activities for wind tunnel tests are provided.
