Description

선박용 스큐 프로펠러(skewde propeller)Ship skewde propeller

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

제1도는 날개응력에 미치는 스큐 각도의 영향을 도시하는 그래프도.1 is a graph showing the influence of skew angle on wing stress.

제3도는 정면의 등익(等翼) 응력선도.3 is a frontal spine stress diagram.

제4도는 날개끝부근의 날개폭이 프로펠러 효율과 캐비테이션(cavitation)에 미치는 영향을 도시하는 그래프도.4 is a graph showing the effect of the wing width near the blade tip on propeller efficiency and cavitation.
