既然能够承受整架飞机重量的降落伞已经存在,我们为何不给民航客机装上降落伞呢?这种想法在理论上可行,但不切实际,其中一个重要原因在于降落伞过于笨重。安装降落伞意味着不得不损失客机的大部分有效载荷,不得不减少乘客人数。 Since a parachute that can withstand the weight of the entire aircraft already exists, why should we not attach a parachute to an airliner? This idea is theoretically feasible but unrealistic. One of the important reasons for this is that the parachute is too bulky. Installing a parachute means having to lose most of the passenger payload and having to reduce the number of passengers.
