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.
The reading and the lecture are both about the advantages of the airship, a very large balloon that was widely used for transportation before 1940s, makes it suitable to use nowadays, because some aeronautical engineers believe that it is so popular. The author of the reading passage presents three points to support this concept. However, the professor disagrees and shows that there are several reasons why it can not use widely.
First of all, according to the reading passage, these balloons consume less fuel than helicopters and airplanes. This point is challenged by the lecture. The professor mentions that although they use minimum fuel, they need lighter gases that air to float, such as helium and hydrogen, that the hydrogen is so dangerous to use and can easily explode. Also, the helium is not a good option because it has a lower lifting power.
Secondly, the author in the reading notes that they can use for the places that are hard to reach and can carry very heavy loads and burdens. Additionally, in the article, it is said that. The professor, however, disproves this point as well and says that for this purpose, airships should have the ability to be steady. However, they are very light and large, and as a result, it is hard to make them steady, and wind can easily move them.
The final point in the reading is that airships are the best alternative to satellites and can be used for telecommunications. Nevertheless, the professor disagrees and points out that airships are not quite ready for this application. He notes that these balloons can reach up to 40 kilometers of the surface, and they use a lot of fuel at this height. Therefore, they should send for refilling many times, and it is not acceptable for these applications.
