How does a Jet Engine work?

Jet Engines are all around us. They can be big or small. Powerful or not so powerful. But they power almost every plane that you will probably ride on in your lifetime. There are many different jet engines out there, powering a range of aircraft, from the 70 seater Bombardier CRJ-700 and the massive Airbus A380 that can seat more than 550 people in 3 classes. Some engine are very big in diameter such as the GE90 that power the Boeing 777-300ER and the much smaller Pratt & Whitney PW6000 that powers some Airbus A318s. So how do these massive jetliners fly? Because of jet engines of course. And here's how they fly:

Picture of the Week

About a week ago, there would be a new weekly post, just for the amazing pictures people take. These can be pictures of airplanes flying, landing or taking off. It can also be pictures of an airport (like below) inside outside or from on top. Or a lego plane that you built. Or a sketch of an airport or airplane. It can be a collage of pictures: airports and airplanes together! So send us your pictures! You can do that by clicking here.

An Air France, Pakistan International Airlines and British Airways aircraft are seen at the gate.

Here are some examples of pictures that you can post.

Send in a collection of your lego planes!

Or send in a sketch for an airport!

How does an Afterburner work?

Many military jets, like the F-18 and the SR-71 take off from short airstrips and aircraft carriers to aid with special missions. But, how do they gather enough speed in such a short distance? How do they fly without stalling? This is all thanks to the afterburner. So, here comes the real question: How does an afterburner work?

 First off, a jet engine, like many other engines, is a reactor 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 exhaust 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.

Modern jet engines use a turbine to improve the fuel efficiency 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 efficient. 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.

Welcome to Aeroworld!

Welcome To Aeroworld!

Started up as a school blog known as Aerospot, Aerospot was the blog for many school assignments and leisure with many blog posts about aviation. Little did I know that people from around the world, including the United States, France, United Kingdom, Australia and many more countries came to Aerospot to find and learn new things. Our most popular blog post was How Does an Afterburner Work? And that was an assigned weekly blog post for school. Soon, Aerospot had more than 5000 views, a significant milestone for us, especially considering it wasn't intended to be an encyclopedia like Wikipedia. As the school year came to an end, and a good bye to our teachers and peers, I finally figured that people shouldn't go looking for information on a non-sophisticated school blog, but instead a professional aviation blog. That marked the birth of Aeroworld. After more than 8 months of individual coding, creating of many forms and survey and a Privacy Policy (which we really tried to make very simple and comprehensible, unlike thousands of other policies) and the hardest thing, figuring out what our first post should be aside from this one. We'll figure it out eventually, that's for sure. We promise that all the information on this site is true and reliable. And it's a real promise. You can use us as a reliable resource for any of your work, whether it may be looking for things casually, or find information for a school project, you can use Aeroworld for anything.

This place is perfect for professionals looking for a little something, students trying to find information or what the case may be.

All of that is to our right!

We will hopefully have a weekly post about an interesting topic, and hopefully a photo of the week on Aeroworld. And a monthly survey :) that will be on the sidebar of our page.
