Description

선박용 프로펠러Marine propeller

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

제1도는 날개표면의 경계층과 프로펠러 후류(slipstream)의 예시도, 제2도는 선체뒤의 웨이크(wake)의 예시도, 제3도는 웨이크에서 블레이드팁으로부터 발생된 와류(vortex)의 피치각 변화의 예시도, 제4도는 블레이드 팁으로부터 발생된 와류의 피치에 대한 실험결과도.FIG. 1 illustrates the boundary layer and propeller slipstream of the wing surface, FIG. 2 illustrates the wake behind the hull, and FIG. 3 illustrates the pitch angle change of the vortex generated from the blade tip at the wake. 4 is an experimental result of the pitch of the vortex generated from the blade tip.
