今年我和女儿坐飞机从上海回石家庄,在登机前,我女儿突然一边看着飞机一边问我:“妈妈,为什么飞机的发动机都是挂在机翼下方,而不是放在机翼上方呢?”听到这个问题,我也一时语塞。仔细想,不仅民用飞机是这样,战斗机也是将副油箱、各种导弹、传感器等都装在了飞机机翼下方,没有一架飞机会在机翼上方放置装备。这是为什么呢?想要回答这个问题,就必须先对飞机的主要结构和飞行原理有一定的了解。 This year, my daughter and I fly back to Shijiazhuang from Shanghai. Before boarding, my daughter suddenly asked me while looking at the plane: “Mom, why are the engines of the aircraft hanging below the wings instead of above the wings ? ”" Hear this problem, I also speak for a while. Think carefully, not only for civil aircraft, but also for fighter jets, missiles, sensors, etc., all mounted underneath the wings of the aircraft. No aircraft would place equipment above the wings. Why is this? To answer this question, we must first understand the main structure of the aircraft and the flight principle.
