Dean’s Message

I am pleased to writein this first issue of theEAC-AIAA studentnewsletter. I hope thatthis be the first of many

EAC-AAS Chapter activities and events to follow thisyear.As we are approaching the fall semester of theacademic year 2009-2010, I would like to welcomeback our returning students. I hope that you had apleasant summer vacation (a short one for some dueto internship program and summer courses!!), andyou are ready for another year of learning and excitingexperiences. As you know, last year witnessed thegraduation of our first batch from the two academicprograms (Aeronautical Engineering and Air TransportManagement). For those graduates, a new era justbegan, in which they will be independentlyencountering new challenges and experiences asthey strive to establish a career in their field ofspecialization or proceed with postgraduate studies.To them, “First” mission is accomplished but willalways be remembered and so will it for you, soachieve the task, enjoy the day, and create joyfulexperiences for tomorrow.

I would also like to welcome new students to EAC-AAS. I hope that you experience a smooth andpositive transition to university life. I urge you toalways seek advice, clarification, and guidance fromfaculty members and staff as well as your seniorcolleagues, when needed. I also encourage you toparticipate in extracurricular activities and be activemembers of the EAC-AAS student body.

Wish you all the very best

Another year to the Chapter.

It has been a year since Emirates AviationCollege started its student branch of the AmericanInstitute of Aeronautics and Astronautics. Thestudent chapter’s main objective is to enroll highlymotivated students who have the potential ofcoming up with challenging and innovational ideasfor a successful student branch.

Currently the members of EAC-AIAA chapter carryout tasks which are essential for the mentalenhancement of every individual associated withthe group. One such example is our very famousMini Skill Club.

On weekly bases various activities are held by themembers on concepts which are usually knownby everyone but not really understood in a practicalsense. The club was an initiation by those studentswho took the responsibility of teaching somethingnew yet simple. They were not professionals buthad a great deal of knowledge about whateverthey taught.

When talking about activities I am not only talkingabout the fun part associated with it but also theoutcome that it has achieved out of it. Themembers have developed a great deal of selfconfidence, they have improvised on theircommunication skills by giving presentationstalking to other people about what we are allabout. Not only this, they have also experiencedthe commitment that every responsibility requires.

Coming to an end of the article on behalf of everystudent of the college and the faculty, I wish thenew officers of the branch all the very best withthe first edition of EAC-AIAA newsletter, ThePhoenix. I hope they take the student chapter tonew heights of creativity.

I would also like to thank our sponsors ‘EDUTECH’for their continuous support.

“How did they fly?” the kid wondered, “How didthey invent the aeroplane? Please tell me dad!”“They did not invent it,” replied the father, “Theyworked hard to bring together the pieces oftechnology at their time, and that is how theWright Brothers got to fly their first aeroplane.”“Many people were able to fly before them, butthey were the first to take-off with their selfpowered aeroplane.”

Many people remember the Wright Brothers asthe first people to fly. Very few know that theiringenuity was in getting the right pieces of thepuzzle together. Before them, many people wereable to fly in different ways!

In the late 19th century, a German engineer,fascinated by the birds was one of the pioneersof flight. As a matter of fact, the results andobservations he made during his flights wereoriginally used by the Write Brothers to designsome of their early aeroplane trials.

Otto Lilienthal was born in 1848 in Germany.During his engineering career, Lilienthal was asuccessful engineer with at least one inventionof a very successful steam engine. In 1891, the43 year old engineer successfully flew his firstdesigned and manufactured glider. In thefollowing five years, Otto Lilienthal successfullyconducted almost 2000 flight with about 200different aircraft of his design. His last flight wason the 10 of August 1896 when he tragicallydied when his aeroplane crashed.

The short aviation career of Lilienthal left behinda legacy of an engineer who was able to tamethe air and ride it successfully. Also, he recordedresults of his flight tests, to a very good levelof accuracy using them to develop better designsand leaving them for those who would use it infuture.

“I want to build my own aeroplane too,” thekid said while his eyes were glimmering withexcitement, “Please teach me how to do it dad!Pleeeeease.”

Concorde... an aircraft that made supersonictravel a reality. Concorde’s unique shape witha pencil thin cabin and vast delta wing enabledit race across the sky at 3 km every 6 seconds.Elegant, luxurious, graceful and above all withan airspeed of 2,200 km/hr, it was a consideredas a symbol of prestige with a near-perfectsafety record. But it was perhaps tragicallypredestined that Concorde wouldn’t retire withits flawless record and an accident in which113 people perished in just 120 seconds sealedConcorde’s fate.

On 25th July 2000, all the passengers hadchecked into the Air France’s Concordethat was bound to travel from theCharles de Gaulle Internationalairport in Paris to NewYo r k . Tw o

minutesafter takeoff, the Air

France aircraft crashed in flames into theHotelissimo hotel in the town of Gonesse northof the capital. 113 people were charred to deathin which 109 were passengers and crew onboard 4 from the hotel.

By rewinding the event of that fateful day andby going deep into investigation it was revealedwhat really happened.

The French bureau of Air Accident’s topinvestigators went on a journey to unravel whatcaused the deadly chain of events whichculminated into this “symbol of safe flying”tragic demise.

At first, every bit of wreckage was taken foridentification and analysis. The recoveredblackbox was thoroughly analyzed and it wasdiscovered that there was no sound of explosion

or any role of terrorism either, in it. Now thespotlight was on those 120 seconds from thestart of Concorde’s final take off. The datarecorders reveled that during the takeoff, therewas sudden loss of power in both engines onthe left wing and immediately the black boxpicked up a dramatic warning from the controltower saying that they had noticed huge fireon behind the left wing but the flight had passedthe point of no return and didn’t have sufficientrunway length to stop safely. The question that

was raised herewas, why didt h e y l o s epower at suchcritical time?

A f t e r a ni n t e n s einvestigation,

t h e F r e n c hinvestigators made a

shocking revelation.They found out that, 5

minutes prior to the Concorde’sdeparture a Continental Airlines

DC-10 had taken off from that samerunway and a 43-inch piece of metal

had fallen off from its engine mounting.During the Concorde’s takeoff and 81 seconds

before the crash, the tire hit the metal stripwhich lead to the explosion of the tire andmassive 4.5 kg massive chunk of rubber fromtire flew at high speed up into the wing wherethe fuel tank were situated. The delta shapedwing was not designed to withstand such animpact and when the rubber chunk hit the wing,it set a pressure wave which found the weakestpoint in the fuel tank and blew a plug outwardsleading to the leakage of the fuel tank. Buteven though the fuel gushing over the enginedidn’t catch fire, in fact it needed a spark toignite this fuel and it was found that during thetire explosion, one of the pieces of the tire flewdirectly above the landing gear bay and brokethe power cable.

This exposed power cable wires whipped aroundexposed airflow and led to spark and came incontact with the leaking fuel leading to the

ignition of the fuel. The intensity of this fire was so immense thatthe wings had started to melt and disintegrating the pilot’s veryessential control to land or takeoff. The crew had to shut downengine number 2 in response to a fire warning but was unableto retract the landing gear, hampering the aircraft’s climb. Withengine number 1 producing little power, the aircraft was unableto gain height or speed, entering into a rapid pitch-up then aviolent descent, rolling left. After this, the aircraft had completelygone off control, wasn’t able to remain airborne and crashed intothe airport hotel beneath it.

Concorde, till then the world’s only successful airliner, ended itsperfect 25 years safety record destroyed in 120 seconds. Threeweeks after the crash all the Concorde flights were grounded andthe two airliners Air France and British Airways that flew Concorde,had to make major safety modifications such strengthening thetires so that they remain functional even after a punctured by a30 cm blade, casing of fuel tanks with bullet proof Kevlar linersto resist punctures and enforced electrical harness in the mainlanding gear bays. Fourteen months after the crash, Concorderesumed passenger flights but the cost to maintain and upgradingthe ageing fleet was sky high. Passenger numbers had startedto decline sharply and at last on 24th October 2003, Concordecarried its passengers for the last time. The first era of supersonicpassenger travel had come to an end; Concorde today is no morethan a museum relic.
