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 ability 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 similar to those provided by satellites, and at a considerably cheaper cost.
Largely being replaced by the aircrafts and helicopters prior to 1940s, some engineers still believe that airships could gain its' position again. The writer supports the idea by mentioning some merits of airships over aircrafts while the speaker discards all these possible amenities because they are not likely to implement successfully.
The first dispute revolves around the benefits of having engines for lifting movement and the associated fuel consumption. The professor argues that in order to ensure vertical movement using the balloon, airships require gases lighter than air such as Hydrogen and Helium which have their own problems and disadvantages. For instance, Hydrogen can create fire and cause accidents which was quite common during 1940s or before. Meanwhile, Helium gas, despite its' inert nature, is difficult to find and also very expensive. So, using Helium in the airships will not be an economical decision. However, the article claims that dependence on fuel will lower the cost compared to the aircrafts and thus airships would be a good choice to bring economical boons.
Moreover, another topic of debate focuses on the loading and unloading facilities of the airships in the remote places. The narrator finds this challenging since it requires stability and slow movement in those locations. As airships are proposed to carry large as well as heavy logs and also lifted with balloons full of gases, it is tough to be steady and make the operation successful. Particularly, during windy condition, it would be really daunting to hold the balance and consequently there is high possibility to fall on some accidents with the tress. Nonetheless, the passage support the fact that airships could mitigate the disadvantages of carrying heavy loads and large number of weights without any troubles.
Last but not the least, the argument is related to the use of airships as the replacement of satellites. The speaker is not convinced with the idea because the airships are not fully developed for it. For example, at present the airships can fly to a height of 14 km from the surface, the height that covers strong winds. As a result, the airships need to consume its' fuel to resist against the wind storm and its' fuel can't last for a long duration. So it needs to descend to recharge again and frequent charging and discharging will make the whole process interrupted. Therefore, the substitution is not fruitful till now. On the contrary, the text argues that airships would reduce the costs if they are launched to perform the tasks by the satellites.
