How It Works-Amazing Vehicles

(Ann) #1
Undercarriage
The undercarriage was unusually strong due to the
high angle the plane would rise to at rotation, just
prior to take off, which put a tremendous amount of
stress on the rear wheels in particular.

Nose
Concorde’s nose drooped to help visibility on
take off and landing and straightened in flight.

Passenger cabin
Concorde could carr y 92
passengers or be
reconfigured internally
to carry up to 120.

Cockpit
Concorde’s were the
last aircraft BA flew
that required a
flight engineer in
the cockpit with the
pilot and copilot.

Thrust-by-wire
Concorde was one of the
first aircraft to use an
onboard computer to help
manage its thrust levels.

A nd yet Concorde still had to contend
with the heat generated by supersonic
fl ight. The nose – traditionally the
hottest part of any supersonic aircraft


  • was fi tted w ith a v isor to prevent the
    heat reaching the cockpit while the
    plane’s fuel was used as a heat sink,
    drawing heat away from the cabin.
    Even then, owing to the incredible
    heat generated by compression of air as


Concorde travelled supersonically, the
fuselage would extend up to 300
millimetres, or almost one foot. The
most famous manifestation of this was a
gap that would open up on the fl ight
deck between the fl ight engineer’s
console and the bulkhead.
Traditionally, engineers would place
their hats in this gap, trapping them
there after it closed.

End of an era
On 25 July 2000, A ir France Flight
4590 crashed in Gonesse, France,
killing all 100 passengers and nine
crew as well as a further four on
the ground.
A lthough the crash was caused
by a fragment from the previous
aircraft to take off, passenger
numbers never recovered and
were damaged still f urther by the
rising cost of maintaining the
ageing aircraft and the slump in air
travel following the 9/11 attacks.
A s a result, on 10 April 2003, A ir
France and British Airways
announced their Concorde fl eets
would be retired later that year.

Despite an attempt by Richard
Branson to purchase BA’s Concorde
fl eet for Virgin Atlantic, the planes
were retired following a week-long
farewell tour that culminated in
three Concordes landing at
Heathrow, and the ver y fi nal fl ight
of a Concorde worldwide landing
in Filton, Bristol.
BA still owns its Concorde fl eet:
one is on display in Surrey, a
second is being kept near-
airworthy by volunteers at the Le
Bourget A ir and Space Museum,
and a third, also at that site, is
being worked on by a joint team of
English and French engineers.

The sonic boom
Sonic booms are generated by the passage of an object through the air. This passage
creates pressure waves that travel at the speed of sound. The closer the aircraft gets
to the speed of sound, the closer these waves become until they merge. The aircraft
then forms the tip of a ‘Mach cone’, the pressure wave at its nose combining w ith the
fall in pressure at its tail as it passes to create the distinctive ‘boom’ sound.
