This group presentation summarizes key aspects of the Concorde supersonic passenger jet. It introduces the group members and presenter, then discusses the Concorde's nose and visor mechanism, ogival delta wing design, Olympus engines and their special features, intake system, and two accidents - the 2000 crash of Air France Flight 4590 which was caused by debris from a previous flight puncturing a tire and damaging the fuel tank.

3. Introduction
 Concorde, the world’s supersonic passenger aircraft
cruise at twice the speed of sound.
 It was operated by British airways and Air france.
 It retired from the service on October 24 ,2003 with it’s
last commercial flight from Newyork to Heathrow.

4. Nose and Visor
 The concorde visor is made to deflect at 5 deg at taxiing &
takeoff and 12.5 deg at landing.
 Both the nose and visor mechanism are hydraulically
controlled from the aircraft.

7. Challenges faced
 The metal visor with its internal periscope through which
the pilots viewed the outside world, was a metal cover.
 But it allow sufficient visibility to be able to fly Concorde.
 This configuration demands the pilot to take up and
approve for the certification.

8. Ogival delta wing
 The Concorde wing was designed to fly with separated
vortex. The leading edge is sharp in order to favor flow
separation.
 The lift will continue to increase for angles of attack up to
40 degrees or so.
 At low speeds, it produces lift as the conventional wing
and vortex lift is responsible at higher angles of attack.

10. Engine
 Concorde engine is powered by Rolls-Royce/Snecma
Olympus engine. It is twin spool engine with a 14 stage
compressor has the compression ratio of 80:1.
 It is the most efficient jet engine in the world at Mach 2.

11. Features
 Nimonic 90 is a Nickel-Chromium-Cobalt alloy, having
high stress-rupture strength and creep resistance at high
temperatures up to about 950°C (1740°F).
 At cruise, the pressure of the air at the compressor face
by a factor of more than six over ambient by efficiently
decelerating the flow.
 The pressure in the combustion chamber was 80 times
higher than ambient.

12. Intake
 It was therefore necessary for the engineers to slow the
air down from Mach 2 to Mach 0.5
 Changes in ramp angle alter the in-take of air and
create a shockwave system that originates at the ramp
angle.

14. Challenges faced
 The reason for the change from the 593D to 593B was
that when the Concorde specifications were upgraded to
improve the range
 But increased take-off weight demanded a 12 per cent
increase in thrust. This could have been obtained by
development of the 593D.
 Concorde’s exhaust smoke changes the previously can
annular combustion chamber to annular vaporizing type.

15. Accidents
 On 25 July 2000, Air France flight 4590 crashed during at
Paris airport, France.
 The accident caused due to the bursting of tire which is
due to the debris of the DC 10 aircraft took-off before the
concorde.
 The debris causes the tire to puncture so that the high
pressure air from the tire to damage the fuel tank to leak
causing accident
