Embodiment Construction

[0034] All features disclosed in this specification, or all disclosed steps in a method or process, may be combined in any way except mutually exclusive features and / or steps.

[0035] Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), unless expressly stated otherwise, may be replaced by other equivalent or alternative features serving a similar purpose. That is, unless expressly stated otherwise, each feature is but one example of a series of equivalent or similar features.

[0036] like figure 1 As shown, it is a schematic diagram of the structure of this embodiment. In this embodiment, the water-cooled support rod includes a rod body 1 and a water-cooled jacket 2 wrapped on the surface of the rod body 1. The water-cooled structure is formed between the shape structure of the water-cooled jacket and the surface of the support rod. for:

Abstract

The invention discloses a water-cooled support rod and a processing method thereof. The connected water-cooled jacket and the support rod respectively have a first water channel and a sixth water channel which are not connected to each other and are arranged between the water-cooled jacket and the surface of the support rod along the axial direction. The water channels are arranged in the water cooling jacket parallel to the second water channel, the third water channel, the fourth water channel and the fifth water channel, and all the water channels are mutually independent structures, which are connected in turn to form a complete water channel structure; Method and 3D printing technology combined processing method to design and process fully water-cooled struts, improve water-cooling efficiency, reduce strut temperature gradient, suppress strut deformation caused by temperature changes in wind tunnel tests, and improve the accuracy of hypersonic wind tunnel force testing .

Description

technical field [0001] The invention belongs to the technical field of aerodynamic measurement of aerospace force measurement test, and specifically relates to a water-cooled support rod and its processing for the problem of deformation of a support rod caused by a sharp rise in the temperature of a flow field during a hypersonic wind tunnel test. method. Background technique [0002] During the force measurement test of the hypersonic wind tunnel, the temperature of the flow field rose sharply to about 800K (when Ma=8) within a few minutes after the wind tunnel was started, and the test model, balance, strut, and wind tunnel support mechanism were all affected by the flow. The influence of the field temperature produces different temperature changes. The test proves that since the strut is directly exposed to the flow field, the temperature change is far more severe than that of the balance inside the model, and there is an obvious temperature gradient on the upper and lowe...
