Transcript of Concorde Flight 4590 Disaster

Concorde Flight 4590 Disaster:
Death of 113 People
July 25,2000

1) 1 ton over take off weight.
2) 1 hour before the plane took off there was replacement of a thrust reverser pneumatic motor and rear bogie truck.

-After this disaster Air France
expected to invest more than
30 million Euros
-The results of this investment came in the form of a few new safety features including:
Cost after these improvements: Over 40 million Euros or 46 million dollars.
Further improvements may include:
- Radar system
-Safety Checks

Proposed areas of improvement:
-Fuel tank
-Landing gear/undercarriage
-Weight
150 Kevlar-Rubber composite fuel tanks liners were added to each plane
Engineering Problem
"Near Zero Growth" tires designed by Michelin
By:Elle Mountain,Eric Mattia,Kyle George, Cale Thygesen,Anthony Sorrenti
Possible Cause 1
Cause 2
2) Tire cut by metal strip on runway
Cause 3
3) Rubber from tire causes shock wave throughout
Cause 4
4) Fire breaks out causing loss of thrust
Changes to the interior were made to improve comfort and reduce weight
Concorde's Impact on the Environment
1) Concorde was not the most fuel efficient plane out there with about
2 gal/sec
(compared to 747's
1 gal/sec
).

Concorde's Impact on Business-AirFrance
1) In 2001 AirFrance paid a settlement of $150 million to the families of the victims.
2) AirFrance was cleared of any guilt and turned against Continental.






Could not fly across the Atlantic Ocean fast enough.
There needs to be a faster way to travel long distance.
A faster flight from Europe to New York would increase trade and make for more efficient business between continents.

Engineering Problem
A Concorde flight from Europe to New York takes about three and a half hours.
An average flight for non Concorde flight is about 8 hours.
Traveling westward with the five hour time difference, means that the Concorde lands before local time catches up with departure time.

Concorde's Impact on Business-John Taylor
1) The mechanic who repaired the DC10-30,John Taylor, was convicted in court, in 2010 of manslaughter. He was faulted for improper attachment with the use of titanium instead of aluminum and erratic drill holes.
2) In 2012, he was exonerated because "criminal manslaughter charge was unjustified."
3) After the incident, John Taylor was speculated to be divorced and depressed, feeling an immense amount of guilt.


4 Rolls Royce Olympus 593 Mrk610 Turbojet with 38,050lbs thrust each.
Equipped with afterburners, increased preformance 20% at full thrust during take-off.
Max cruise speed of Mach 2.04(1350mph) at 60,000ft.

Concorde's Impact on Business-Continental
1) In 2010, AirFrance had asked for $20 million from Continental,but only $1.3 million was awarded in damages and had to pay a fine of $265,000.
2) In 2012, the French appeals court overturned the criminal manslaughter convictions, however the civil charges remained.

The Delta Wing Design

In addition to the near 50 million dollars it cost the company, distrust of the airline, and fewer people flying due to the 9/11 disaster would eventually lead to the demise of the Concorde in 2003.
http://www.concordesst.com/wing.html
Creates sufficient lift by increasing angle of attack with low drag that increases efficiency at high speeds.
A traditional aircraft's wing creates a swirling vortex only at the wing tips. On a delta wing at low speeds, a vortex is formed nearly along the entire wing surface and produces most of the lift at low speeds.

Concorde's Impact on
Society
Change of airflow through engine with variable intake controls.
At supersonic speeds, control of airflow increases the stability of the engines and plane.
http://www.concordesst.com/powerplant.html
Creates Cushion during landing due to down wash.
Creates smoother landing at higher speeds.
http://www.concordesst.com/wing.html
Able to be configured during different stages of flight.
Long pointed nose increase aerodynamics.
High angle at take off and landing so not to obstruct pilot's view and accounts for Delta Wing lift.
Visor for protecting windshield
Droop Nose Positions

http://www.concordesst.com/gear.html
Nose gear situated behind flight deck, as well as retracts forward.
Main gears retract because they would be too long to fit in bays.
Fitted with splash guards to prevent water in the engine intakes.
First aircraft to be fitted with Carbon Fiber brakes that are now standard with all commercial aircraft.

After researching this disaster, we have concluded that it was primarily the fault of the mechanic John Taylor who did not make the appropriate repairs to the DC10-30, leading to the metal strip on the runway, and also the fault of the Concorde not having a high enough factor of safety.
