关于汽轮机巡航速度？ 这里指的是早期的汽轮机在船舶航行速度为巡航速度时的效率较低。 见 https:///wiki/steam_turbine 。巡航速度一般为船舶航行最快速度的50% the quest for economy was even more important when cruising speeds were considered. cruising speed is roughly 50% of a warship's maximum speed and 20-25% of its maximum power level. this would be a speed used on long voyages when fuel economy is desired. although this brought the propeller speeds down to an efficient range, turbine efficiency was greatly reduced, and early turbine ships had poor cruising ranges. 查看更多
