Wind tunnel test deflector

Abstract

The invention provides a wind tunnel test flow-guiding device. The device comprises a base, a flow guiding assembly, an angle adjusting piece and a calibration assembly, a test piece to be examined isarranged on the flow guiding assembly, the flow guiding assembly is used for smoothly transitioning air flow at a wind tunnel air outlet to a surface of the test piece to be examined, the angle adjusting piece is used for adjusting the angle of attack of the test piece to be examined to match a thermal environment state of the set test piece to be examined, the calibration assembly is used for measuring the thermal environment state of the test piece to be examined to calibrate the thermal environment state of the test piece to be examined, and when the thermal environment state measured by the calibration assembly is different from the set thermal environment state, the wind tunnel test flow-guiding device adjusts the angle of attack of the test piece to be examined through the angle adjusting piece to reach the set thermal environment state of the test piece to be examined. The technical scheme of the invention is applied to solve the technical problem in the prior art that a certain section of cabin cannot be examined separately.

Description

technical field

[0001] The invention relates to the technical field of cabin-level wind tunnel tests, in particular to a flow guide device for wind tunnel tests. Background technique

[0002] High-speed and high-speed are the development direction of future aircraft. The aerodynamic and thermal problems of high-speed aircraft are key issues that cannot be avoided. With the continuous increase of the flight Mach number, the aerodynamic and thermal problems are becoming more and more serious. A lot of work has been done in the field to deal with the aerodynamic and thermal problems brought about by high-speed flight. At present, the thermal prediction problem is limited by the existing technology and theoretical development level, and there is still a certain gap between the accuracy and the expectation. In particular, the numerical prediction accuracy is restricted by many interference factors. The wind tunnel test can provide a relatively real application environment. One o...
