戰斗機早已拋棄螺旋槳，可軍艦卻仍在使用，一用就是一百多年。從 1845 年的那場 「拔河」 比賽說起，探究螺旋槳推進的高效、節能、穩定等優勢。對於戰斗機而言，速度就是生命，但軍艦的速度並沒有那麼重要，想要換掉螺旋槳，或許只能等待技術革命。
Fighter planes have long abandoned propellers, but warships are still using them for more than a hundred years. Let's start with the "tug of war" game in 1845 and explore the advantages of propeller propulsion, such as high efficiency, energy saving, and stability. For fighter planes, speed is life, but the speed of warships is not that important. If you want to replace the propeller, you may have to wait for a technological revolution.
