How Does a Jet Engine Move an Airplane?


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.


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.

Why Did I Choose My Major?

When I was child, I always liked to disassemble my toys, especially, the toys that play by batters. Actually, my parents were encouraging me to be engineer. During my teenage period, I used to go with my father to car workshops in the industrial region if his car broke down. I still remember my questions I had asked to my father, which always were formatting as “how that’s working.” Additionally, when I was high school student, my favorite classes were the physical classes in the lab. After I graduated from high school, I got high grads in my scientific materials. Therefore, I desire to be mechanical engineer. I want working on the jet engines of aircrafts in the workshops of my city’s airport. The main reason that why I have chosen this major because I like making movements in my working place more then staying in the office. Finally, I hope to graduate as mechanical engineer to make my parents proud of me.

Strange Food

Actually, I have never eaten strange food because I didn't use to taste the strange food until I know what it includes. Whatever, I remember one time that I tried to eat spicy food. There was one time that I asked my Indonesian server to make delicious Indonesian meal. She asked me for buying some Asian spices from Indonesian Grocery. Because she wants to cook traditional Indonesian meal that called" Gado-gado." After I got the required spices, she said if I want more spices or little. I said without hesitation "yes I want more than you usually do." Than when she finished cooking, I tasted it. The first tasting was good and but the end of tasting I felt like my mouth is burning. Actually, that was only my first attempt to eat something different then I have usually eaten.

Producing More Engine Power


According to Marshall Brain's article "Producing More Engine Power," he points out the variables that auto industry companies compete for creating cars' engines that have strength and efficiency in consuming the fuel. First of all, adding more cylinders or creating larger cylinders to make more power for increasing of engines' power. Second, increase the compression on mixed air and fuel to get more powerful. Third, fill each cylinder with air to give it power by the compression process. Fourth, cool the next air to expand when combustion occurs. Fifth, allow air to flow easily to avoid air resistance. Sixth, make the exhaust of the cylinders go out by the valves to not cause high compression. Seventh, everything should be lighter because the piston changes direction if you aren't in one direction. Finally, measure accurately how much fuel there is in each cylinder by Fuel injection. In conclusion, the author states the variables which car manufacturers try to improve and explains each one and how we can make more engine power.


In my own opinion, the article is generally a little complicated. It has many terms of some parts of the cars' engine which just car experts know. But it is really interesting to me because I like discovering engines and how they work. When I was child, I was always going with my father to cars workshops in the industrial region if his car broke down. I remember many questions that I asked about many things that were in the article. Also, it's exciting to recognize the variables which cars' engines depend on to work efficiently and all cars' countries compete in. Finally, the article entirely was useful giving specific information about car's engine.

My Legacy

I do like to be remembered by my remaining achievements with my faith to Gad. I actually don't care what people are talking about what I did and then they eulogize me. I should make good marks relating to me before my death. I always imagine establishing a big foundation that generally takes care of poor people. I want my foundation help people who can’t buy their medicines. We believe that is good deeds can help dead people in Islam religion. Also for my children, I'll write my experience that I had learned from my whole life. I want my children to learn from experiences that advice them to be more successful than me in their life. I want to leave good marks for generations that might motion me after my death. I should work hard to achieve what I planned. I conclude that is our achievements depend on what we really did for our society in our whole life.

Saudi Tradition

There are many various stereotypes that are from different regions in Saudi Arabia. However, I'll talk about the most traditional one, which many Saudi men used to wear. The Saudi formal clothing consists of the Thob, the Koffiyeh, and the Agal. The Thob is a long dress that is usually made of cotton or wool. The Koffiyeh, also known as Al-Shemag, is a white-and-red headdress. It might be folded and wrapped in different styles around the head. The Agal is a black rope circlet that holds the Koffiyeh in place. Actually, most Saudi men wear this style in working places, schools, and festivals. This style is considered the most popular uniform of Saudi Arabia and the Gulf States. Finally, that symbolizes the Arabic and Islamic clothes.

Mechanical Engineering


Mechanical engineering deals with different applications of mechanical systems using physics principles. Mechanical engineering has improved since the world wars and nowadays it is important to many other fields. Mechanical engineering includes designing machines and engines. Mechanical engineers have basic background of related fields of study. They also need to consider designing machines that are economical and they have to provide safe and good products to people. The mechanical engineering program covers many areas of interest. The first area is designing, which includes drafting programs and mechanisms for different mechanical products. The second area includes making products such as machines. The third area studies “statics and dynamics.” The fourth area studies heat and temperature to make machines such as fridges. The fifth area studies fluids and liquids. The last area is concerned with measurements and instruments. In conclusion, nowadays, mechanical engineering is developing widely, and one of the most common focuses is robotics.


The article is completely understandable. It doesn't have scientific words that nobody can understand. I liked the beginning of the article, which reminded the history of mechanical engineering. Also, it's interesting to recognize which mechanical engineering include. I couldn't imagine that all modern industries are depending on mechanical engineering. In addition, mechanical engineering program that takes in many areas of interest is interesting to me. As well, the article generally is exciting to read and I really learned valuable information about mechanical engineering.
