Description

선박프로펠러날개Ship propeller wing

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도 및 제2도는 각각 추진방향의 반대쪽에서 본 프로펠러의 평면도. 제3도는 본 발명에 따른 프로펠러날개의 후연부분을 제1도 및 제2도에서 각각 A-A선 및 B-B선상의 확대 단면도.1 and 2 are plan views of the propellers seen from opposite sides of the propulsion direction, respectively. 3 is an enlarged cross-sectional view of the trailing edge of the propeller blade according to the present invention on the A-A line and the B-B line in FIGS. 1 and 2, respectively.

Claims (4)

프로펠러축에 착설되어 회전하도록 되어 있고 선박을 전방으로 추진시키기 위한 날개의 회전방향에서 볼때 각각 전연 및 후연과 합쳐지는 압축측면과 흡입측면을 가지고 있으며, 프로펠러날개의 후연은 압축측면과 흡입측면에 부식손상 발생이 예상되는 후연부분이 만곡을 이룬 최소한 한개의 만곡부를 가지고 있고, 만곡부는 프로펠러축의 중심으로 부터 공동손상이 예상되는 날개부분 까지와 동일한 반경거리에 위치하고 있는 선박 프로펠러날개.It is installed on the propeller shaft and rotates, and has a compression side and a suction side that are combined with the leading and trailing edges, respectively, when viewed from the rotational direction of the wing to propel the ship forward. Ship propeller wings located at the same radial distance from the center of the propeller shaft to the wing area where joint damage is expected from the center of the propeller shaft. 청구범위 1에서 상기 최소한 한개의 만곡부는 프로펠러날개가 설계된 추진조건하에서 회전할때 날개의 전체회전을 통해서 공동효과가 만곡부에 생기도록 만들어져 있는 프로펠러날개.The propeller wing of claim 1 wherein the at least one bend is made such that the joint effect occurs through the full rotation of the wing when the propeller wing is rotated under the designed propulsion conditions. 청구범위 1에서 상기 최소한 한개의 만곡부는 프로펠러직경의 0.004배가 되는 내측반경으로 만곡되어 있는 프로펠러 날개.The propeller blade of claim 1 wherein the at least one curved portion is curved with an inner radius that is 0.004 times the propeller diameter. 청구범위 3에서 상기 최소한 한개의 만곡부는 45°내지 90°의 원호로 만곡된 프로펠러날개.The at least one curved portion of claim 3 wherein the propeller wings are curved with an arc of 45 ° to 90 °. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
