The theory is known as the "equal transit time" or "longer path" theory which states that wings are designed with the upper surface longer than the lower surface, to generate higher velocities on the upper surface because the molecules of gas on the upper surface have to reach the trailing edge at the same time as the molecules on the lower surface. " " The error in this theory involves the specification of the velocity on the upper surface. In reality, the velocity on the upper surface of a lifting wing is much higher than the velocity which produces an equal transit time " 人家已經挑明告訴你"不能這樣解釋了" 你還想爭什麼? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.217.5 ※ 編輯: void 來自: 140.112.217.5 (06/09 02:05)
