巨大的椭圆形气球——飞艇,又回来了!我们将有望在5～10年后看到这种名副其实的“空中客货轮”重新穿梭于天际。5年来,全世界几乎都在为飞艇而狂热,就连美国军方也开始斥资对它进行研究。“飞艇热”为何会不期而至?其实,它的爆发并非我们所认为的那样突如其来。可以说,自其诞生之日起,工程师们一直对这种庞然大物青睐有加,即使在快捷保险的飞机时代,仍然对它充满梦想。工程师们认定,飞艇必将大有作为。今天,飞艇可以应用于旅游观光,它庞大的身躯更是—块无与伦比的巨大广告牌;将来,它可以替代飞机运送一些过于笨重或体积过大的物品。 Huge oval balloon - airship, is back! We will see in 5 to 10 years to see this veritable “Air Passenger” re-shuttle in the sky. For almost five years, almost all the world has been enthusiastic about airships. Even the U.S. military has begun to spend money on it. Why does “airship fever” come unexpectedly? In fact, its outbreak is not as sudden as we think. It can be said that since the day of its birth, engineers have always favored such monoliths, even though they are still full of dreams in the aircraft insurance era. Engineers believe the airship will do a great job. Today, the airship can be used in tourism and sightseeing, its huge body is - an enormous block of unparalleled billboards; in the future, it can replace the aircraft carrying some bulky or over-bulky items.
