Description
본 발명은 액체로켓 엔진 개발의 초기 단계에서 수행될 연소시험 이전에 액체로켓엔진의 단일 분사기에 대한 수력학적 특성인 분무의 질량분포 자료를 획득하기 위한 비연소(수류) 시험장치로서, 수류시험 대상 단일 분사기에서 분사되는 다양한 모의 유체 조합에 대해 분사기의 하부에서 추진제의 이차원적인 질량분포를 안정적으로 계측하는 인젝터의 분무형태를 측정하는 튜브다발 형상의 패터네이터에 관한 것이다.The present invention is a non-combustion (water flow) test apparatus for acquiring mass distribution data of a spray which is a hydraulic characteristic for a single injector of a liquid rocket engine before a combustion test to be performed at an early stage of liquid rocket engine development. It relates to a tube bundle-shaped patternator that measures the spray pattern of an injector that reliably measures the two-dimensional mass distribution of the propellant at the bottom of the injector for various simulated fluid combinations injected from a single injector.
종래 방전가공에 의한 사각격자 방식의 패터네이터는 분사되는 유체를 모으는 부분의 형태가 사각형의 구멍으로 이루어져 있으며, 이 사각형의 구멍 하측에서는 원형의 튜브를 연결하므로 제작상 채집상부에서 채집하부로의 유로의 단면적 변화가 형성되어 병목현상으로 원활한 배수가 용이하지 않다.The square grid pattern patterner by the conventional electric discharge machining has a rectangular hole in the shape of collecting fluid to be injected, and in the lower part of the rectangular hole, a circular tube is connected so that the flow path from the top of the collector to the bottom of the collector The cross-sectional area of is formed, and bottlenecking is not easy to drain smoothly.
이로 인해 많은 유량이 분무될 시 채집관에서 넘치거나 분무된 액적들이 튀어 다른 격자로 채집되는 등 오차 발생 요인이 많은 결점이 있다.As a result, when a large flow rate is sprayed, there are many defects in generating errors, such as overflowing or sprayed droplets from the collection pipe and being collected by another grid.
이는 채집관의 크기 즉 격자의 크기를 증가시킴으로써 해결될 수 있으나 분해능이 현저히 떨어지는 단점이 있다.This can be solved by increasing the size of the collecting tube, that is, the size of the grid, but has a disadvantage in that the resolution is significantly lowered.
즉, 측정의 정확도를 높이기 위해서는 격자의 크기를 최소화하는 것이 유리하나 제작상 어려움이 있고, 채집하부와의 연결시 유로의 단면적 변화를 초래하는결점이 있다.That is, it is advantageous to minimize the size of the grid in order to increase the accuracy of the measurement, but there is a difficulty in manufacturing, and there is a defect that causes a change in the cross-sectional area of the flow path when connecting to the collecting bottom.
본 발명은 이러한 종래의 결점을 해소시키기 위하여 안출된 것으로, 이차원적인 질량분포를 정확하게 계측하기 위해서 채집 오차 발생 요인을 최소하 하는 것이다.The present invention has been devised to solve such a conventional drawback, and minimizes a collection error occurrence factor in order to accurately measure two-dimensional mass distribution.
본 발명은 채집부가 튜브다발의 방식을 취하고 채집관내의 단면적이 축소되는 병목현상이 없어 분사기의 유량이 큰 경우에도 측정부로의 배수가 원활히 이루어질 수 있도록 하는 것이다.According to the present invention, there is no bottleneck in which the collecting part takes the form of a tube bundle and the cross-sectional area in the collecting pipe is reduced, so that even if the flow rate of the injector is large, drainage to the measuring part can be made smoothly.

이는 테프론 튜브(6)내의 원활한 배수를 위한 채집하부쪽에서의 흡입장치 설치시 기밀을 유지해야 하기 때문이다.This is because airtightness must be maintained when the suction device is installed at the lower side of the collection for smooth drainage in the Teflon tube 6.
테프론 튜브(6)의 선단이 연결되는 채집용기(8)는 보정된 눈금의 규격품이며 투명한 재료를 사용하고 가이드레일을 사용하여 한 열에 15개 정도씩 일체형이 되어 동시에 분리될 수 있도록 측정부(5)를 설치한다.The collecting container 8, to which the tip of the Teflon tube 6 is connected, is a standard product of a calibrated scale, and uses a transparent material and a guide rail, which is about 15 pieces in a row, so that it can be separated at the same time. Install).
채집용기(8)는 동시에 채집하부(12)에서 분리될 수 있으며 하나 하나씩 분리되도록 하며, 바닥에는 고정부(7)를 설치하여 수평 이동 및 고정이 가능한 구조를 제공하는 것이다.Collecting container (8) can be separated at the same time can be separated from the lower portion 12 and to be separated one by one, to provide a structure capable of horizontal movement and fixing by installing a fixed portion (7) at the bottom.
이러한 본 발명은 액체로켓 엔진 개발의 초기 단계에서 수행될 연소시험 이전에 액체로켓엔진의 단일 분사기에 대한 수력학적 특성인 분무의 질량분포 자료를 획득하기 위한 비연소(수류) 시험장치로서, 2차원적인 질량분포를 측정하게 된다.The present invention is a non-combustion (water flow) test apparatus for acquiring mass distribution data of spray, which is a hydraulic characteristic for a single injector of a liquid rocket engine, before a combustion test to be performed at an early stage of liquid rocket engine development. The mass distribution is measured.
채집관(1)의 상부에서 분무되는 액적들은 채집관(1)의 상부에서 수집되는 것으로, 다발관으로 형성된 다수의 채집관(1) 상부에서 액적들이 분무되어 수집된 후 수직으로 이동되어 테프론 튜브(6)를 통하여 측정부(5)의 채집용기(8)에 각각 채집되는 것이다.Droplets sprayed from the upper part of the collecting tube 1 are collected at the upper part of the collecting tube 1, and the droplets are sprayed and collected at the upper part of the plurality of collecting tubes 1 formed of the bundle tube, and then moved vertically to be a Teflon tube. (6) is to be collected in each of the collection container 8 of the measuring unit (5).
이때 채집관(1)은 상부에서 분무되는 액적들을 수집하는 것이며, 채집관(1)의 끝단 수직 배치 높이가 모두 일치하므로 분무된 액적만을 수집할 수 있고, 채집관(1)의 끝단에 형성된 에지각(1')을 통하여 분무되는 액적이 되튀김에 의한 수집을 방지하여 채집관(1)에 들어온 액적만을 채집할 수 있도록 하여 측정 오차를 줄이도록 하는 것이다.At this time, the collecting tube (1) is to collect the droplets sprayed from the top, because the height of the vertical arrangement of the ends of the collecting tube (1) can only collect the sprayed droplets, the edge formed at the end of the collecting tube (1) The droplets sprayed through the angle 1 'are prevented from being collected by flipping so that only the droplets entering the collecting tube 1 can be collected to reduce the measurement error.
채집관(1)에 분무된 액적만이 수집되어 수직설치를 통한 하측으로 이동 후 3차원 형상의 곡면부를 갖도록 연결된 테프론 튜브(6)를 통하여 하부로의 배수가 용이하게 이루어진다.Only the droplets sprayed on the collecting tube 1 are collected and moved downward through the vertical installation, and then easily drained downward through the Teflon tube 6 connected to have a three-dimensional curved surface.
상기 채집관(1)이 설치된 지지판(2)은 경사면(22)을 형성하고 있어서 채집관(1)에 채집되지 않는 분무액적들이 외측으로 원활하게 배수 처리되도록 하며, 지지판(2)에서 배수된 유체는 유체 배수관(3)을 통하여 외부로 배수되므로 채집 오차에는 영향을 주지 않게 된다.The support plate 2 provided with the collection tube 1 forms an inclined surface 22 so that spray droplets that are not collected in the collection tube 1 can be drained to the outside smoothly, and the fluid drained from the support plate 2 is disposed. Since it is drained to the outside through the fluid drain pipe (3) does not affect the collection error.
테프론 튜브(6)를 통하여 배수되는 채집 유체는 채집용기(8)에 공급되므로 측정부(5)의 눈금을 통하여 정확한 분무의 질량분포 자료를 제공하는 것이다.Since the collecting fluid drained through the Teflon tube 6 is supplied to the collecting container 8, it provides the mass distribution data of the accurate spray through the scale of the measuring unit 5.
