  2. The running condition would be deteriorated and at last the parts of the engine would be damaged if the revolution were reduced too low. the propeller must be redesigned or be modified in this situation. people usually modify the propeller rather than change the propeller because it will be more easily and economical

    此時若要更換新的必然造成經濟上過重的負擔,較方便可行的方法是對原來的採取切邊修改的方法,減少的直徑、盤距,使的扭矩減小,變「輕」 。
  3. Presently most of the theoretical method to predict the propeller - induced hull pressure fluctuation is based on the calculation method in which the pressure is induced by pulsating source in infinite flow. the calculation method is adopted and the corresponded computer program is complied. the propeller - induced hull pressure fluctuation due to blade thickness, blade load, cavity thickness and the change of the cavity volume can be analyzed respectively in the computer program

    目前,誘導的船體表脈動壓力的理論預報方法,大多是以無限流場中點脈動源誘導的周圍流場的脈動壓力的計算方法為基礎的,本文採用該方法編制了計算程序,可以分別考慮葉厚度、葉負荷、葉上空泡厚度及其體變化在船體表指定位置上產生的脈動壓力。
  4.
