Description

항공기의 노즐 페어링 결합장치{Joining apparatus for the nozzle fairing of aerospace}Joining apparatus for the nozzle fairing of aerospace

본 발명은 항공기의 노즐 페어링 결합장치에 관한 것으로, 더욱 상세하게는 항공기의 노즐 페어링의 결합구조를 보다 간단하고, 효율적으로 구현한 항공기의노즐 페어링 결합장치에 관한 것이다.The present invention relates to a nozzle pairing coupling device for an aircraft, and more particularly to a nozzle pairing coupling device for an aircraft that more simply and efficiently implement the coupling structure of the nozzle pairing of the aircraft.

일반적으로 항공기에는 공기의 흐름을 평활하게 하기 위한 목적으로 항공기의 각종 구조부에 씌워져 결합되는 유선형 덮개의 일종인 페어링이 사용된다. 이 페어링은 그 설치되는 부분에 따라 다양한 형상과 구조로 구현되며, 또한 결합되는 구조부에 따라 각기 다른 결합방법으로 결합된다.In general, a pairing is used in an aircraft, which is a kind of streamlined cover that is covered and coupled to various structural parts of the aircraft for the purpose of smoothing the flow of air. The pairing is implemented in a variety of shapes and structures depending on the part to be installed, and is also coupled in different coupling methods depending on the structure to be joined.

이중에서 항공기의 엔진 노즐부분에 설치되는 페어링은 사선형태의 외주면을 가진 물고기 비늘 형태로 되어 노즐 외측으로 별도의 금속재질의 결합밴드에 의하여 강하게 밀착되어 결합되게 되어 있다.Among these, the pairing installed in the engine nozzle portion of the aircraft is in the form of fish scales having an oblique outer peripheral surface is to be strongly adhered to the outside of the nozzle by a separate metal coupling band.

여기서 이 결합밴드는 효과적인 결합상태의 유지를 위하여 그 결합 토오크 값이 정확히 조절되어 결합되어야 한다. 따라서 결합밴드는 필수적으로 결합상태의 조절이 가능한 결합장치에 의하여 그 결합이 이루어진다.In this case, the coupling band should be coupled by adjusting the coupling torque value precisely to maintain the effective coupling state. Therefore, the coupling band is essentially made by the coupling device that can adjust the coupling state.

그런데 종래에 항공기의 노즐 페어링을 결합하기 위한 결합밴드를 고정시키는 결합장치의 구조는 상당히 복잡한 2단계 래치구조로 되어 있고, 무게 또한 상당한 중량을 가진다. 그리고 복잡한 래치구조에 의하여 주변 구조물의 구조도 상당히 복잡하여 구조물과 결합장치의 제조단가가 높아지게 되고, 설치 및 조절을 위한 작업효율도 낮은 문제점이 있다.However, in the related art, the structure of the coupling device for fixing the coupling band for coupling the nozzle pairing of the aircraft has a fairly complicated two-stage latch structure, and also has a considerable weight. In addition, due to the complicated latch structure, the structure of the surrounding structure is also quite complicated, thereby increasing the manufacturing cost of the structure and the coupling device, and there is also a problem of low work efficiency for installation and adjustment.

본 발명은 전술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 간단한 볼트 및 너트 구조로 결합 및 제조가 가능하여 그 제조단가 및 중량을 줄일 수 있도록 하고, 또한 정확한 토오크 값의 조절이 가능하도록 한 항공기의 노즐 페어링결합장치를 제공하기 위한 것이다.The present invention is to solve the above problems, an object of the present invention is to be able to combine and manufacture in a simple bolt and nut structure to reduce the manufacturing cost and weight, and also to enable accurate torque value adjustment It is to provide a nozzle pairing coupling device of the aircraft.
