The paper addresses a recent major facility upgrade of the VTI T-38 wind tunnel. More than 30 years after the wind tunnel commissioning, a novel solution for test automation developed by VTI brings more than an order of magnitude improved testing accuracy, higher versatility of information obtained from the tests, as well as significantly reduced wind-on time and energy consumption, confirming the VTI T-38 ability to perform tests with the uniform quality from low subsonic speeds via transonic conditions and up to high supersonic speeds.
