Description

소음여자 및 압력변동의 고산출 및 저레벨을 성취하기 위한 선박 프로펠러Ship propellers to achieve high output and low levels of noise excitation and pressure fluctuations

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 프로펠러 블레이드와 이에 관련된 폐쇄판이 프로펠러 샤프트선을 통과하는 평면에서 교차하는 것의 개략도.1 is a schematic view of the propeller blades and their associated closure plates intersecting in a plane passing through the propeller shaft line.

제2도는 액체 베인(vein)을 둘러싸는 회전면의 기능양상을 나타낸 사시도.2 is a perspective view showing a functional feature of a rotating surface surrounding a liquid vane;

제3도는 액체 베인을 둘러싸는 회전면과 샤프트 라인을 포함하는 일반적인 평면 사이의 교점을 나타낸 도면.3 shows an intersection between a plane of rotation surrounding a liquid vane and a general plane comprising a shaft line.

제4도 및 제5도는 허브를 갖는 프로펠러의 일반적인 블레이드의 사시도.4 and 5 are perspective views of a general blade of a propeller with a hub.

제6도는 프로펠러의 일반적인 블레이드, 프로펠러에 외접한 실린더 및 액체 베인을 둘러싸는 회전면에서 말린 유선을 나타낸 사시도.FIG. 6 is a perspective view showing a streamline rolled around a general blade of a propeller, a cylinder circumscribed to the propeller, and a rotating surface surrounding the liquid vane. FIG.
