THE BRILLIANCE OF CONCORDE

ABSTRACT

The Concorde was one of the greatest gems of the aviation industry in the 20th century. It was a result of 20 years of engineering in a nutshell. It was the culmination of two giants participating together to make the ultimate travel machine, the Concorde.

The Iconic Concorde

What was it for, Reason for its Development?

The Concorde was primarily made for the transatlantic flight from New York to London as these are the 2 main hubs of the world and needed faster traveling between them. In the early days of aviation, the transatlantic flight was about 13 hours, this was greatly reduced after the introduction of the jet engines which took only 7 hours, and the time was further reduced by the introduction of planes like the Concorde. The time of traveling was reduced to a mere 3 and a half hours at supersonic speeds.

A Little Bit of History:-

In the early days flying faster than the speed of sound was considered very difficult or even impossible. People thought it couldn’t be done, the laws of physics wouldn’t allow it. But an array of speed records followed after the first supersonic flight by Chuck Yeager in 1947.

THE SOVIET CONCORDE: TUPOLEV Tu-144

In the meantime, the Russians had their own version of the Concorde ready, with basically the same design and innovations. It was the only supersonic jet to ever carry commercial passengers apart from the Concorde. It was called the Tupolev Tu-144. This aircraft was more dangerous, uncomfortable, and loud than the Concorde.

Flaws of Tupolev Tu-144:-

Obviously, the Tu-144 did all the things that the Conocde could do but a little worse. Unlike the Concorde, it was not built around the customer experience, and also it was made around the stolen ideas which let it have a bad experience. Tu-144 had a very short range because it burned so much fuel that in a single go it couldn’t even cross the Soviet Union.

HOW & WHY DID IF FAIL?

From the very beginning, the engineers working on the project knew that the Concorde isn't going to sell well because of all the things required to make it suitable for a perfect plane. The idea of a supersonic plane was ahead of its time and the challenges it proposed were not technologically possible. That’s why it was never economically feasible and was doomed in the end.

Problems of a Flying Concorde, Reason for its Failure

  • The engines of the plane produced very loud noises during takeoff, the noises were in the range of above 100 dB, also during the flight, the plane produced sonic boom sounds which were not appreciated by the people on the ground, this resulted in the banning of the plane in some of the countries.
  • It frequently was returned to the shop to get some maintenance done. The technology used was so cutting edge and ahead of its time that the aircraft always needed something more done to it.
  • Used twice as much more fuel than a traditional jetliner for the same distance traveled. The amount of fuel used during taxing on the runway was equivalent to a car using in 6 months.
  • The fuselage was very thin, it was often referred to as pencil-thin. Due to this it only had very few seats and couldn't carry more passengers.
  • The initial cost of operating the plane was very high, the economics didn’t favor the plane either, on top of that include bad political interference which ultimately decided the fate of the plane.

SPECIALTY OF CONCORDE

  • The shape of the Concorde was as unique as the shape of its nose. It had a long sharp-pointed nose. The thinness serves many purposes but the most important of them all is that it is very good for the aerodynamics of the plane at high Mach number.
    But the design of the nose posed a problem in the sense that it was too long to see in front of the plane during landing, that’s why it had 2 positions, one being the normal position and the other being the extended position. Due to this property, the mechanisms of the nose became very complex.

  • Flying at supersonic speeds requires engines that are at least twice as powerful as the regular subsonic jet engines. It also required stream-lined wings and airframes that can withstand the stresses caused due to high velocity and high temperatures.
    The engine on the Concorde was a Rolls-Royce/Snecma Olympus 593. It had four of these engines capable of pushing the aircraft at supersonic speeds. The engines generated about 18.7 metric tons (180kN) of thrust. Together with the four engines burned 6,771 gallons (25,629 liters) of fuel per hour.

  • Blue paint caused problems for the Concorde:-
    In the 90s the Pepsi was on a mission to rebrand their soda and were to shift to a new color scheme of blue, which will be different from Coca Cola. This whole advertisement campaign was named as Project Blue with a budget of about $5 Million.
    For the campaign, the Concorde was to be decorated with blue paint with the word “PEPSI” written on the fuselage. From the factory, the Concorde was painted with special heat-absorbing paint which was different from traditional aircraft paint. Due to the high velocity of the aircraft, the outer surface generated a lot of heat which the paint used to absorb. But due to the introduction of new blue paint, the aircraft didn’t remain a good absorbent and hence was limited to Mach 1.7, well below its cruising speed of Mach 2.1. Thankfully, the campaign only lasted 2 weeks, after which the plane returned to its usual business.

Apart from the Concorde, and the moon landings being the most ambitious projects of the 20th century, there was one more thing that matches the uniqueness. It was the Blackbird SR-71.
