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 carying 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.
In this set of materials, the reading and writing both discuss the Airship. The article strongly postulates that few aeronautical engineers are speculating that airships have certain advantages over airplanes and helicopters so they could be popular soon, and provides three reasons to endorse its idea. however, the lecture mentions that there are several reason that proved the claims made in the reading as dubious and impractical, and gainsays each of them.lly
First and foremost, the writer begins by asserting that airship have advantage to airplanes as they do not require effort for vertical lift that consumes lots of fuel in case of airplanes" engines. On the other hand, the lecturer dismisses the point by insisting that though airship carry less feel there are other problems associated with the usage of hydrogen gas and helium in airships. To be more specific, he argued that hydrogen gas is combustible that could lead to various air accidents. In addition, helium is a expensive gas and light in weightthey cannot be used for lifting airships. As a result, it is economically not favorable and safe.
Furthermore, the lecturer mentions that in order to pick up tree logs from forest, airships must have a steady landing and take off. whereas it is arduous to perform the carrying logs task steadily due to the reason that airships are provided with light gasses. It would result in a collision. Especially if there is a gust of wind, airship carrying trees explode into something and could cause damage. These claims clearly refute the writer's implication that airships could be transported to hard to reach places such as forests as they do not need runways for landing and taking off.
ultimetely, the writer wraps up its arguments by declaring that arship could supersede satellites as they could reach enough height moreover the do not need refueling unlike others satellites. NOt surprisingly, the lecture takes an issue with point by contending that airships can go only up to height of 14 km, and if there is a strong wind they would not stay at one place and might have to exert strong force to stay at one place that consumes it's energy, their tour might not remain uninterrupted.
