My Favourite Phoster
I had a few so I will put each Phoster that caught my eye:
This one caught my eye since the words "LEST WE FORGET" made me remember of Rememberance Day, which to me, is such a memorable event.
This one caught my eye because it showed be a dock which appears to be very long and a light blue sky and tells me a message: Go on, Go as long as you can go, there is no end to things"
This one caught my eye since it tells me to read everywhere no matter where you are, even if you're in bed.

Aerodynamics: What is it?
Aerodynamics: What is it?
By: Aerospot
Aerodynamics doesn't seem to interest the general public. Normally, when someone hear the word "Aero", they often refer it to airplanes or the massive engines abord a jet. Aerodynamics doesn't just apply to the world of advanced aviation and its partner, aeronautics. Aerodynamics apply to planes, engines, cars, trains, boats and even yourself, you have aerodynamical properties. Aerodynamics involves, in aviation, drag, thrust, weight and lift, the four principles of flight. When you run, you have aerodynamical properties. When you run, you can make yourself faster by changing your aerodynamical properties. For example, if you run with a clenched fist, you create drag, therefore, making yourself slower and harder for you to run fast. But, when you run with your hand straight at your side against the wind, you reduce the amount of drag making it easier for you to run and, therefore, run faster. This is a basic rule of aerodynamics, which involves 2 of the principles of flight indicated above. Aerodynamics is an interaction with a moving object. This means that anything that moves, has aerodynamics involved. In advanced science, aerodynamics is a branch of dynamics. Cars have aerodynamical properties too. A car produces drag when it hits the oncoming air. The thrust in this part is the engine, which provides power to move forward. Aerodynamics, which involves trains and cars, also has significant in the area of air and flight. Specifically moving to aviation and aeronautics. In aviation, you do not have only lift and drag, you have all sorts of things like turbulence (differences in air pressure), pressure changes, even strong winds can affect the airplanes performance and even it's aerodynamical characteristics. The winds can be a factor of thrust, or a factor of drag. If the wind is a tailwind (a wind that goes in the direction of the plane - push the aircraft forward) is a thrust factor. If the wind is a headwind (a wind that goes in the opposite direction of the plane - pushes the aircraft backward) is a drag factor. The reason why a headwind is like a drag factor is because it makes it harder for the aircraft to gain speed. The reason why a tailwind is like a thrust factor is because it makes it easier for the aircraft to gain speed. Remember, aerodynamics is not just about planes, about every moving thing.

How Does an Afterburner Work?
How does an Afterburner Work?
A jet engine, like many other engines is a reaction engine. It works by absorbing air, compressing the air in a combustion chamber where the air expands greatly and then it is shot back out at the back of the engine as air and exaust at about Mach 2 or about 1500 miles/hour. This is known as thrust. An engine absorbs air and shoots it out as a hot gas.
An afterburner is a part of an engine that acts like a booster. The afterburner is another stage fitted on only a certain amount of their engines like that of a Rolls Royce/SNECMA Olympus 593 fitted on the Supersonic Concorde. The afterburner injects fuel directly into the exaust stream expanding the air even more and creating nearly 50% more thrust to the engines' thrust.

Modern jet engines use a turbine to improve the fuel effiency of a jet engine. This allows the jet engine to work at lower speeds and therefore lower temperatures. The turbine compresses the air before fuel is injected in the combustion chamber. This modern engine is extremely efficent. For example, on a Boeing 747-400, the aircraft can earn up to 19 miles per passenger gallon.
An afterburner is a part of an engine that acts like a booster. The afterburner is another stage fitted on only a certain amount of their engines like that of a Rolls Royce/SNECMA Olympus 593 fitted on the Supersonic Concorde. The afterburner injects fuel directly into the exaust stream expanding the air even more and creating nearly 50% more thrust to the engines' thrust.
The advantage of an afterburner is it can significantly add more thrust without adding weight, complexity and higher speeds and temperature to the engine. An afterburner is basically just a number of fuel injectors to compress the air further and increase the thrust of an engine.
The disadvantage of the afterburner is that it uses a lot of fuel to generate its power.
The afterburner was an amazing design for the 1970s to 1990s but now has come out of commercial service due to the retirement of the Concorde. Military aircraft like the F-18 and the SR-71 still has afterburner to aid with special missions or to take-off from a short airstrip.
To learn more about the afterburner, click here - very interesting
Summary:
This article is about an afterburner which is a stage in certain jet engines that compresses the air to create more thrust. The afterburner does have to burn more fuel to perform this. Military aircraft still use afterburners to help aid the performance of the aircraft and this is very important.
Reflection:
This article is very important to me because it was essential to the developpement of many military aircraft and the supersonic Concorde. To develop new technologies, it is important to look to the past to build the future. With advancing technology, we don't know if previous technology is best for us. The afterburner, in my opinion, is an aviation and aeronautical symbol. The afterburner is a great design giving its excellent performance. What is good about the article is the way the afterburner works. Very cool and interesting.
