HAV304航空器是英国最近研制的世界上最大的航空飞行器。它的外形像是飞机、飞艇和直升机的混合体。HAV304航空器长92米,比世界最长的民航客机空客A380还长11米,机身足有一个足球场那么宽敞。它有两层楼那么高,以纯金属建造,使用氦气为动力,非常环保节能,能节约大量能源,油耗只是传统飞机的1/4。HAV304航空器不需要跑道起降。这个巨无霸航行的速度为148千米/时,却能在空中飞行超过3周的时间。
The HAV304 aircraft is the world’s largest aerospace vehicle recently developed in the United Kingdom. It looks like a mixture of aircraft, airships and helicopters. The HAV304 aircraft is 92 meters long and 11 meters longer than the world’s longest civil airliner, the Airbus A380. The fuselage has enough space for a soccer field. It has two floors so high, built of pure metal, the use of helium-powered, very environmentally friendly energy saving, can save a lot of energy, fuel consumption is only 1/4 of the traditional aircraft. HAV304 aircraft does not require runway movements. The giant is sailing at 148 km / h, but can fly in the air for more than three weeks.
