Problems solved by technology

[0004] In order to prevent the transition unit from falling off in advance, the pre-cut dot marks in the finished rubber strip should not be too deep, and the surface processing quality of the test models varies greatly, and some materials have poor bonding viscosity with the adhesive backing, causing the strip Time transition elements are often carried along and do not stay on the model surface as expected
At this time, the operator can only fix a single transition unit with a thin iron wire on one side, and then remove the adhesive strip, so that the transition unit fixed with the iron wire is easy to slip on the model, and the operation can only be performed individually (two meters The aircraft model in the two-stage wind tunnel generally needs to paste thousands of transition units, and some models need to carry out the transition position influence test, which may need to be pasted several times), which is time-consuming and labor-intensive, and delays the progress of the test

Embodiment 1

[0031] refer to Figure 1 to Figure 3 shown. The invention discloses a fast sticking device for a transition belt of a wind tunnel test model. The quick pasting device 10 at least includes a roller 11 and several thimbles 12 . The thimble 12 is used to press each transition unit on the transition zone to the surface of the wing model 20 to assist the separation of each transition unit from the transition zone.

[0032] Preferably, the roller 11 is a cylindrical structure. The ejector pins 12 are arranged on the side wall of the roller 11, and the distance between the heads of adjacent ejector pins 12 is equal to the distance between adjacent transition units on the transition belt.

[0033] Preferably, a groove 13 is provided on the side wall of the thimble 12 close to the head. The groove 13 is used to engage the transition belt during the rotation of the roller 11, so as to drive the transition belt to separate from the attached wing model.

[0034] Preferably, the open...

Embodiment 2

[0041] On the basis of embodiment 1, the present invention also discloses a fast pasting method for a transition belt of a wind tunnel test model. Described fast pasting method comprises the steps:

[0042] Step S1: Determine the pasting position of the transition belt on the wing model 20, and mark the pasting position of each transition unit by connecting lines or dots with a marker pen.

[0043] Step S2: align a certain thimble 12 of the quick pasting device 10 disclosed in Example 1 with the transition unit on the transition belt. And press the transition unit to the pasting position of the transition unit marked in step S1, and at the same time snap the transition belt into the groove 13 of the thimble 12 .

[0044] Step S3: Control the roller 11 of the pasting device to roll along the lines of the pasting positions indicated in the step S1, so that the thimble 12 presses the transition units on the transition belt to the wing model 20, so that the transition units are b...

Abstract

The invention discloses a fast pasting device for a transition belt of a wind tunnel test model. The fast pasting device at least includes a roller and several thimbles, the roller is a cylindrical structure, and the thimble is arranged on the side wall of the roller , and the distance between adjacent thimble heads is equal to the distance between adjacent transition units on the transition zone. The wind tunnel test model columnar transition belt quick pasting device of the present invention has the advantages of simple structure, low processing and manufacturing cost, simple and convenient use, and easy to use. The transition unit is automatically compressed by means of rollers, which saves working time, especially for parts with narrow operating spaces such as lips and connotation channels in the delivery room, which has great advantages. Therefore, the wind tunnel test model columnar transition belt fast sticking device of the present invention can effectively improve the transition belt sticking efficiency, reduce the rework rate, reduce the preparation time of the wind tunnel test, and improve the quality and efficiency of the wind tunnel test.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel tests, and in particular relates to a fast pasting device and a pasting method for a transition belt of a wind tunnel test model. Background technique [0002] At present, wind tunnel test is the main means to obtain the aerodynamic characteristics of aircraft and other aircraft. During the wind tunnel test, the transition and transition position of each part of the model have a great influence on the surface flow state of the model, which in turn has a great influence on the resistance and moment characteristics of the whole machine. If it cannot be simulated accurately, the engineering application of the wind tunnel test data value. The Reynolds number is an important factor affecting the boundary layer transition and transition position, while the Reynolds number of the model in the wind tunnel test is low (unless it is a full-scale Reynolds number wind tunnel), the viscous effect is large...
