Resumed concorde specs

Post by SilverOne » Wed Jul 27, 2005 11:56 am

Concorde is probably the most famous commercial aircraft ever built. it has come to be regarded as both a work of art and a triumph of mechanical engineering. Indeed, its unprecedented ability to sustain a cruising speed of Mach 2.05 for up to three hours remains unchallenged.

Concorde was the world's only operational supersonic passenger aircraft in 1965, cruising at twice the speed of sounds at around 1350 mph, and at an altitude of upto 60.000 ft , ( over 11 miles high ). A typical new york crossing took a little less than three and a hafl hours,. travelling westwards, the five-hour tieme differencemeant concorde arrived before it had take off, in local time at least.

Great britan and france started working separately towards a supersonic aircraft in 1962 they decided to develop one jointly [ french / english ... not a good combination right ]now back to the subjecct.
This partnershop , between airfrance and british aircraft ( now british airwais )amd sid aviation ( now under the aerospatiale banner ) , led to 20 concordes being built. Each country manufactured one prototype one preduction and eight production aircraft. the first flight of the british aircraft. The first flight of the british prototype took place from filton, brustol on april 9 4976. concordw was subjected to 5,000 hours of testing by the time it was certified for passenger flight , making it the most tested aircraft in history.

the comercial supersonic era was inaugurated on junuary 21 , 1976, with british airwais flying from lndon heathrow to bahrain and air france from paris to rio , concorde fastest transatlantic crossing was on febreuery, 1996, when it completed the new york to london flight in 2 hours and 52 minutes and 59 seconds.

of the 16 pruduction aircraft , 14 where availeble for sale, british airwais was the world's first supersonic airline. They ordered 5 concorde in july 1972, airfrance later ordered 4 , becouse no other airlines puchased concorde , the remaining unsold planes were given to airfrance and british airwais.

concorde is unique while it measures 204ft in length , it streched between six and ten inches in flight, due to the eating of the frame. This also ensured that it was effectlifvly corrosion free. The characteristic droop nose was lowered to improve pilots' visibility for take-off and landing.

the four engines are often erroneously reffered to as "specially modified rolls-roice/scnema olympus enfines". infact the olympus engine was originally developed for the vulcan, to mk 320 for about 18,000 lbs of thrust. a reheated version was developed for the TSR2. WHen a engine was neede for the concorde project, bristol offered to develop this engine further , while rolls rouce derby said they develop a complete new engine. As bristols offer was obviusly much cheaper , it was accepted. So the olimpus engine was developed; the development was principally an extra LP compressor stage to the "3b" standar for the prototype concordes
WHen the concorde design was enlarged to bring it up from 60+ to 100 passengers, this engine was developed to the "593" standart", When the aircraft was finalised rolls "tidied up" the "593/610" ( as they were not supposed to be devoping the engine further). This version of the engine gave 32,000 lbs of thrust dry and 380,140 with reheat. the reheat was only used for takeoff, and going transonic - at cruise the reheat was not necessary. This was a majore problem with Concorde's russian rival, Concordsky. IT needed reheat at cruise so it had a 1000 miles shorter range. Reheat is a thirsty way of deveoping thrust and , despite was you read , it's not a "final stage" as it is in the form of a second burning stage in the jet pipe. so as not to upset the engine too much, a rather complex variablearea nozzle is neccessary. the olympus engine was certainly the most powerfull turbojet in civil operationg.
today's "big" engine achieve their 100,000 of thrust by driving big fans ( ducted proppelers realy ) but these would be quite unsuited for supersonic flight.

Compared to other commercial airliners , Concorde provided a unique passenger experience , both britishairwasis and france configured cabin as single class with arround 100 seats.

the unique experience of passing thought the sound barrier was less dramatic then it would be expected, guven the turbulent history of supersonic flight. The moment would be announced by one of the three pilots, otherwise the slight surrge in aceleration would be missed.

at twice the normal cruising altitude, turbulence was rare and the view from the windows certainly showed the curvature of the earth. During supersonic cruise, althought the outside air was typicly -60 C, air friction would eat the external skin at the front of the plane to around +120 C mmaking the windows warm to the touch and producing a notiecable temperature gradient along the length of the cabin.
Most remarkably concorde was the only plane to outrun the sun. on certain eealy evening, transatlatic flight were departing from heaththrow to or paris, it was possible to take off at night and cathch with the sun -- from the nose ou could see the sun rise on the wesst. you can be one year younger ...

what is reheat ? :

rehat system
the reheat system operates by burning fuel within the jet pipe to increase the temperature of thr turbine exaust gases, This increaces the velocity of the exaust gases thereby producing additional thrust.the reheat is normaly used at take off and during the transonic acceleration


i went to my lil manual and took a few details out and gathered the most important , nothing special , i was just bored :?

no , i writed it from the manual "Concorde Proffesional" i got up here at home :lol: :lol: :lol:

yeah i writed it up , took me 30 mins i think. u can see my errors cuz i wasnt looking at the keyboard, and some letters are kinda writed twice.

Reheat is the same as afterburner...couldn't tell whether you were asking or answering. ;-)
