Aircraft & Speed

Last week article on Hyper sonic Realm by Aire turned few heads. The idea of a passenger aircraft travelling at Mach5+ (five or greater than the speed of sound) is indeed exhilarating.

Why isn't there a passenger aircraft like this? I mean, in a world of instant food, instant info, instant satisfaction...why isn't the aviation industry trying to design and build a super awesome passenger aircraft that can fly at Mach 5+?

This led me to think about the evolution of aircraft design and speed. 

At the beginning, all aviators trying to fly was focusing on the first step - Take Off. Everyone was trying to build something that can take off. Some succeeded only to find that there design did not consider cruise and landing phases, which unfortunately was learned the hard way. 

Anyway, Wright Brothers was not only famous for inventing the aircraft. Although George Cayley is the one who discovered Airfoil, Wright Brothers were the one who invented a system to control airplanes by manipulating the flow of air. And so at the beginning years of aviation everyone focused on taming wind to their wills. 

When we mastered the power of flight, the new focus was speed. This particular interest in speed was propelled due to World Wars. Speed was crucial in dogfights. Speed allowed to do manoeuvres in air to gain tactical advantage for the fighters.

Speed was a promising endeavor. Pushing the speed limit higher and higher became the sole focus of aviators. Designers made breakthrough in science and technology to gain higher speeds. Records were made, many milestones were achieved; many of the records are still celebrated to this day.

With the advancement in technology, it was being apparent that speed comes at a price. The price was fuel. Even though great advancement was made to reduce drag and increase weight to thrust ratio; it was clear to the aviators that fuel can increase speed to insane values.

In the 1970s and 80s when the availability of fuel was plenty, governments of countries sponsored companies to build aircraft that can fly faster and higher. The national security was at stake like always. Little did the mass public cared about environment, global warming and the depletion of natural resource. Once the money and stock exchange got affected by these; people began to notice.

By 1990s, a new array of focus based on saving the planet was planned. It became obvious that fuel cost a lot & made pollution. The only solution was to compromise speed and increase other features like bed and hot bath. 

This is the reason why you now see an aviation industry focused on creating aircraft that are more comfortable, luxurious and consume less fuel. They are so into comforting people that now we can adjust lights according to our mood in the new Boeing 787 Dreamliner. There was no light adjustment in Concorde because, you know, nobody cared - they will reach the destination soon. 

Aviation is an industry that has to adopt to the new rules of the new world. The brilliant aviators working in this industry strive hard to fight the challenges head on. They do their best with the time they have.

Until next time.

Hypersonic Realm

I'm Arun (Aire) another aviation and aircraft enthusiasts like you, a day dreamer most likely.This my first blog posting in which I would like to share my ideas with you.

Hyper-sonic commercial jetliners.

Yup! Definitely Awesome.

I know this sounds fictional and weird to some of you,when things like fuel ,air frame etc comes in mind. Unfortunately Concord and TupolevTu-144 both have been retired and grounded due to huge operational cost and pollution; no supersonic commercial jets has flown since these two legendary aircraft. 

The Legend

Alright lets keep off all those and talk about speed again, not supersonic; hyper-sonic this time ,speed 5 times and more (5+ Mach) of sound ie: New York to India (12600KM) in just few minutes!! Exciting ah !! 

Well that could be pushing technology to its limits.Lets keep it unlimited.Introducing masters of speed -  RAMJET and SCRAMJET.


Both are types of experimental engine designed for speeds greater than that of sound.They are jet engines with no moving parts,relying on the enormous pressures created by supersonic airflow into the engine to ignite fuel without needing the compressors and turbines used in turbofan engines found on conventional jet planes.

In a ramjet ,the combustion chamber-where the air mixed with fuel and ignited -only works at subsonic speeds.So intakes slows the air down ,releasing some of its energy as a shock wave ,but this reduces fuel efficiency.

The scramjet is an innovation on the ramjet in which the combustion chamber is specially designed to operate with supersonic airflow. Scramjet is simply an acronym for supersonic combustion ramjet.

Let's wait till this Fantasy become Reality .

Thank you for your time .Appreciate your comments!!!

Until Next time.

Right Caption

" What should be my status? " , my friend asked by showing a picture of him (so called selfie) with a docked Emirates A380 in the background. The pic depicted my friend going to board the jumbo jet for the first time. Well, for him, like all of us, a person who loves aviation; flying in an A380 is a pretty big deal. What interest me however was his decision to upload it into social medias with "right" caption.

After much thought, he finally wrote:

 " A journey of Epic proportions.

A right caption indeed.

We Are Back

After a long break, we are back. Aviation world has seen much exciting and rather unusual events in the past months. Out of all news, MH370 is the most outstanding one. The mysterious disappearance of a state-of-the-art Boeing 777 baffles the aviation industry to this day.

We will surely have an article about these in the coming days. But this article is just to remind you guys about our blog's purpose.

This blog stands to Cherish the passion of aviation. This blog stands as a tribute to the aviation industry. Celebrate Aviation.

All we ever wanted was to contribute something to aviation world.

We understand that there are millions of people around the world who loves aviation, who in their hearts has an overflowing passion towards the freedom of flying. This blog is dedicated to those hearts.

It is our humble try to do something worth to these hearts.

Weekly two articles will be posted, one on every Sunday and other on every other Wednesday.

See you guys soon.
