Description

비행선용 추력편향장치{Thrust Vectoring System of Airship}Thrust Deflection System for Airships {Thrust Vectoring System of Airship}

본 발명은 비행선구조물에 추력편향장치를 설치하여 비행선의 저속 조종성 및 이착륙거리 단축을 위하여 필요한 추력편향(벡터추력)기능을 구현하기 위한 장치로 추력을 발생시키는 프로펠러 디스크를 회전시켜 원하는 방향의 추력을 얻기 위한 비행선용 추력편향장치에 관한 것이다.The present invention is to install a thrust deflection device in the airship structure to implement the thrust deflection (vector thrust) function required for low-speed maneuverability and shortening landing and landing distance by rotating the propeller disk to generate a thrust to the thrust in the desired direction It relates to an airship thrust deflection device for obtaining.

비행선은 일반 항공기와 비교할 때 동적 양력에 의존하지 않고 부력에 의해 부양할 수 있기 때문에 비교적 저속 또는 정지상태에서도 운용할 수 있다.Airships can be operated at relatively low speeds or at rest because they can be floated by buoyancy rather than dynamic lift compared to standard aircraft.

하지만 저속 비행 시에는 비행선의 제어면을 이용한 자세 제어 효과가 미약한 단점을 갖고 있다.However, in low-speed flight, the attitude control effect using the control surface of the airship has a weak disadvantage.

따라서 비행선의 상승 및 하강 속도의 증가에 의한 이착륙 거리 감소 및 자세제어를 위해서는 추력편향(벡터 추력) 기능이 요구된다.Therefore, the thrust deflection (vector thrust) function is required to reduce the take-off and landing distance and attitude control by increasing the airship ascent and descent speed.

특히 비행선의 이착륙거리 단축은 비행선의 운용에서 매우 중요한 문제이다.In particular, shortening the take-off and landing distance of the airship is a very important problem in the operation of the airship.

일반적으로 추력편향기능을 이용하는 경우에 이륙거리는 약 1/5로 단축되고, 착륙거리는 약2/5로 단축될 수 있기 때문에, 최근에 개발되는 대부분의 비행선들은 벡터 추력 기능을 갖추고 있으며, 이것은 비행선이 대형화 될 수록 반드시 필요한 기술이다.In general, when the thrust deflection function is used, the takeoff distance can be reduced to about 1/5, and the landing distance can be reduced to about 2/5, so most of the recently developed airships have a vector thrust function. As it gets bigger, it is a necessary skill.

벡터 추력을 구현하는 방법은 크게 두 가지가 있으며, 하나는 틸트 로터와 같이 프로펠러 디스크 면의 방향을 바꾸어 주는 방법이고, 다른 하나는 프로펠러 후류에 베인을 설치하거나 또는 엔진의 노즐방향을 바꾸어 줌으로써 벡터 추력을 얻는 방법이다.There are two ways to implement vector thrust. One is to change the direction of the propeller disk face like the tilt rotor, and the other is to set the vector thrust by installing vanes in the back of the propeller or by changing the nozzle direction of the engine. How to get.

종래의 비행선 방향 제어 시스템은 본 발명의 출원인이 출원한 공개특허공보 제2000-0067382호(2000. 11. 15. 공개)는 성층권에서 장기 체공하는 비행선의 방향을 선회시키는 시스템에 관한 것으로 비행선 후미에 설치된 프로펠러의 피치를 주기적으로 가변 피치각 제어로 선회 모멘트를 발생시켜 방향을 선회시키도록 하는 것이었다.Conventional airship direction control system is disclosed in the Patent Application Publication No. 2000-0067382 (published on November 15, 2000) filed by the applicant of the present invention relates to a system for turning the direction of the airship in the stratosphere for long-term flight The pitch of the propeller was periodically changed to generate a turning moment by variable pitch angle control.

또한 국제특허출원의 출원공개공보 제1996-7003757호(1996. 8. 31. 공개)는 길이방향 축선과 제1 및 제2단부를 갖는 파일론을 포함하며, 상기 파일론의 제1단부는 비행선으로부터 외측으로 연장된다.International Patent Application Publication No. 1996-7003757 (published Aug. 31, 1996) also includes a pylon having a longitudinal axis and first and second ends, wherein the first end of the pylon is outside the airship. Extends.

파일론은 비행선의 길이방향 축선에 수직한 평면에서 제1단부 주위에서 회전가능하고, 추력생성 조립체는 파일론의 제2단부상에 장착되며, 파일론의 길이방향 축선에 수직한 면에서 회전축선 주위에서 회전 가능하다.The pylon is rotatable around the first end in a plane perpendicular to the longitudinal axis of the airship, and the thrust generating assembly is mounted on the second end of the pylon and rotates around the axis of rotation in a plane perpendicular to the longitudinal axis of the pylon. It is possible.

동력 공급부 조립체는 동력을 공급하기 위해 추력 생성 조립체에 연결되며, 작동 시스템은 조립체를 회전축선 주위로 회전시키도록 하고, 제2작동 시스템은 파일론을 제1단부 주위로 회전시키기 위해 제공된다.The power supply assembly is connected to the thrust generating assembly for powering, the actuation system causes the assembly to rotate about the axis of rotation, and a second actuation system is provided for rotating the pylon around the first end.

그러나 추력을 생성시키기 위한 구조가 복잡하고, 다수의 엔진 및 기능을 필요로 하는 것이었다.However, the structure for generating thrust was complicated and required a number of engines and functions.

본 발명은 비행선의 저속 조종성 및 이착륙거리 단축을 위하여 필요한 추력편향(벡터 추력)기능을 구현하기 위한 장치로 추력을 발생시키는 프로펠러 디스크를 회전시켜 원하는 방향의 추력을 제공하는 것이다.The present invention is to provide a thrust in the desired direction by rotating the propeller disk to generate a thrust deflection (vector thrust) function necessary for low-speed maneuverability and shortening landing and landing distance of the airship.

It is.

그러나 위와 같은 위치에 설치되는 추력편향장치(10)는 비행선 외피(20)에 부착되는 위치 및 작동각도는 실시예를 표시한 것으로 필요에 따라 달라질 수 있는 것이다.However, the thrust deflection device 10 installed at the position as described above is attached to the airship shell 20 and the operating angle is an embodiment that will vary as needed.

추력편향장치(10)는 도 2, 3 과 같이 추력편향장치 회전부(1)와 추력편향장치 고정부(2)로 크게 두 부분으로 나누어진다.The thrust deflector 10 is divided into two parts, as shown in Figs. 2 and 3, the thrust deflector rotating unit 1 and the thrust deflector fixing unit 2.

추력편향장치 회전부(1)는 일자형의 내부에서 호퍼형태로 연결되며 외측으로 내접 스퍼어기어(9)와 연결되어 함께 회전되는 것이다.Thrust deflection device rotating part 1 is connected in a hopper form inside the straight shape and is connected to the internal spur gear 9 to the outside to rotate together.

추력편향장치 회전부(1)는 외측에서 베어링(3)으로 추력편향장치 고정부(2)와 연결되어 자유로이 회전이 가능하도록 하는 것이다.Thrust deflection device rotating part (1) is connected to the thrust deflection device fixing part (2) from the outside to the bearing (3) to enable free rotation.
