How Does a Jet Engine Move an Airplane?


Summary:

In Paul Bright's article "How Does a Jet Engine Move an Airplane?," he explains the four processes of the jet propulsion that are "suck, squeeze, bang and blow," in order. Actually, all jet engine aircraft depend on these processes for taking off. First of all, he mentions the first process that is called "suck," in which the blades flatter the oxygen into the engine and the electronic signals are sent to pipes of plugs to start the burning of fuel for making enough heat to let the air rotate into the engine. Second, he states the second process that is called "squeeze," the importance of the front of engine being wider than the middle of engine to assist in the compression of air to produce a greater quantity of heat and power. Lastly, he concludes with the last process, which ends when it takes off from the land what is called " bang and blow". The mixture of air, spark, and fuel make a great power of energy. This energy tries to find the place that "blow" accrues in compressed conditions. The hot air goes out from the exhaust. In conclusion, the article shows the mechanism of action of jet engines by sucking the air to make the aircrafts fly forward.

Reaction:

In my own opinion, I found this article to be very interesting and informative to me because it is talking about the part of my own major. Now, I could figure out how all aircraft can take off from land by depending on the four processes. Actually, the title encouraged me to read the whole article. A good quote is “that seem too large to get off of the ground. ” because most people think that way. In addition, this article is written in a non-scientific way that might be easier to understand. Also, I liked this, “How a jet engine works really comes down to four stages: suck, squeeze, bang and blow;” this sentence states all the processes briefly. Finally, the article entirely was useful in that it gave me valuable information about how jet engines make aircraft to take off from the land.

hi, this is Paul Bright, author of the article you just referenced. Thanks for using it! I was actually a 10-year jet engine mechanic for the United States Air Force. Worked on the C-17. Thanks again!
