Embodiment Construction
[0031] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The invention provides an engine position adjustment device, which can adjust the front and rear, height and pitch positions of the engine in a wind tunnel test section. The device is divided into four parts, one part is the engine mounting frame 1, and the other three parts complete the front and rear, height and pitch adjustment of the engine.
[0033] Such as figure 1 A test frame that can adjust the position of the engine in multiple directions is shown, including an engine mounting frame 1, a front and rear adjustment device 4, a height adjustment device 3 and a pitch adjustment device 2; a pitch adjustment device 2, a height adjustment device 3, and a front and rear adjustment device 4 Set up in order from top to bottom; the pitch adjustment device 2 is used to realize the pitch adjustment of the engine mo...

The invention relates to a test frame capable of adjusting an engine position in multiple directions, and solves the problem that the engine adjustment bracket of the existing wind tunnel test systemhas high test cost, long design cycle and processing cycle and unable implementation of continuous adjustment and the like. The test frame comprises an engine mounting frame, a front and rear adjustment device, a height adjustment device and a pitch adjustment device, wherein the pitch adjustment device is used for realizing pitch adjustment of engine mounting frame; the height adjustment device is used for adjusting up and down displacement of the engine mounting frame; the front and rear adjustment device is used for adjusting front and rear displacement of the engine mounting frame that isdisposed on the pitch adjustment device; the pitch adjustment device, the height adjustment device and the front and rear adjustment device are sequentially arranged from top to bottom; and the pitchadjustment device comprises a first fixed frame, a first movable frame, a first locking device, a first guiding device, a first lead screw, a first driving device, a nut and a mounting frame.
Description
technical field [0001] The invention relates to a wind tunnel test device, in particular to a test frame capable of multi-directionally adjusting the position of an engine. Background technique [0002] In the wind tunnel test of the test piece, the test piece is placed in the wind tunnel test section, and the relative position between the test piece and the outlet of the nozzle is adjusted to meet the requirements of "full hedging between the incoming flow of the wind tunnel and the spray flow of the test piece" and "the nearness of the test piece". The shock turning position (or engine jet shock wave) is located in the Schlieren window" two conditions. The test piece weighs about 3 tons, and it needs to bear a large impact force during the test. Therefore, it is necessary to conduct wind tunnel tests at different engine installation positions (front and rear, height, pitch), and determine the best engine installation position according to the test results. [0003] The ex...
