An airship is a type of aircraft that flies using a very large balloon filled with a lighter-than-air gas. Airships were an important means of air transportation before the 1940s but are little used today, having been largely replaced by airplanes and helicopters. However, some aeronautical engineers believe that airships could become popular again because they offer a number of advantages over airplanes and helicopters One advantage of airships is that for vertical lift (the force that keeps the ship airborne), they use a balloon that floats rather than an engine. Airplanes and helicopters use engines for both vertical lift and horizontal movement, but airships use engines solely for horizontal movement. So, airships use less fuel than a typical aircraft—thus making their fuel costs more economical. Another advantage of airships is that they can be used in hard-to-reach locations. Unlike airplanes, airships do not require a long runway for takeoff and landing because of their ab巾ty to lift off and land vertically. The only other aircraft capable of ascending into the sky by going straight up and descending straight down to the ground is the helicopter, which can carry only a small amount of weight. Airships, meanwhile, are able to carry very heavy loads. As a result, airships could do jobs that neither airplanes nor helicopters can do, such as carrying heavy logs from forests to distribution centers. Finally, airships could even be used to replace satellites. Currently, satellites are launched into Earth's orbit carrying all kinds of equipment important in telecommunications or in surveying large areas of Earth's surface for military purposes. Since airships can also rise high above the surface and stay there without refueling for a significant amount of time, they could provide services s1m1lar to those provided by satellites, and at a considerably cheaper cost
The article and lecture discussed the possibility of replacing aircraft with airship in the future. The article suggested that there are three reasons which make using airship likely in the future. The lecturer, on the other hand, responded that the arguments made in the article are not solid enough.
To begin with, the article stated that airship can used for vertical lift. According to the article airship can float easily in the air, moreover it does not require engine nor using fuel. The lecturer, however, stressed that airship require a specific type of gases. According to the lecturer, Helium and Hydrogen are used in the airship, and the using of both gases has drawbacks. Helium gas if difficult to obtain, and Hydrogen can catch fire easily which would cause accidents in the airship.
Second, the article pointed out that airship can be used in locations that are hard to reach by aircrafts, which allows using them to pick things from ground. In contrast, the lecturer responded that using airship to pick things should be done slowly and steadily, however it is hard to keep airship steady in the air especially in the presence of strong wind.
Finally, the author of the article emphasized that airship can be used as satellite in the space. The lecturer, on the other hand, countered that airships are not ready yet to replace the satellite. He explained that the airships can rise up to only forty kilometers height above the surface. Moreover, if there is strong wind, aircrafts will use up fuel continuously and need to be refilled.
