n 1976 we could fl y commercially from London to
New York in just three and a half hours. That’s
over 5,550 kilometres (3,460 miles) at an average
speed of 27 kilometres (17 miles) per minute. For
context, the same journey in a Mini Metro travelling
continuously at 97 kilometres (60 miles) per hour
would take close to 58 hours (almost two and a half
days) – and that’s not considering the fact a Mini
can’t fl y!
Today, crossing the ‘pond’ – ie the Atlantic Ocean


  • takes more like seven and a half hours, a trip that
    defi nitely puts the ‘long’ into long-haul fl ight. So,
    this raises the question: what went wrong? A
    one-word answer is suffi cient: Concorde. The
    Concorde supersonic jet, the piece of technolog y
    that allowed such outrageous fl ight times was


retired for good back in 2003 after 27 years of ser vice
(for more information see the ‘End of Concorde’
boxout on p76). Further, no other supersonic jet has
been introduced in its absence – leaving customers
stuck travelling at subsonic speeds no matter where
they wish to fl y around the globe, and having to
endure the longer fl ight times.
Things, however, are all about to change. Driven
by the ever-growing notion of the global village – the
interconnectedness of all nations – and fi red by the
gaping void left behind by Concorde, a new wave of
supersonic jetliners have been put into production,
aiming to pick up where Concorde touched down.
The aim is to radically transform the speed,
effi ciency and impact of future commercial
supersonic travel.

From Lockheed Martin’s Green Machine
concept (a supersonic jet capable of mitigating
the effects of sonic boom) through Aerion
Corporation’s Supersonic Business Jet (a machine
that introduces a radical new technolog y called
natural laminar fl ow) and on to Boeing’s Icon-II
design (an aircraft that boasts far greater noise
reduction and fuel effi ciency) the future of this
industr y is already looking ver y exciting. For the
fi rst time, private companies are collaborating with
the best research institutes in the world (one of
which being NASA) to make supersonic fl ight a
realit y once more, outside of the militar y sphere
that is.
Of course, while the roadmap to realisation is
becoming more concrete with each passing day,

Concorde’s successors are now on the horizon, offering


Mach-shattering speeds, alongside hugely reduced noise


and fuel consumption compared to their famous forebear


THE NEW

CONCORDE

Fuselage
The fuselage has been
designed in line with the
Sears-Haack body, a cigar
shape that grants the lowest
theoretical wave drag.

Engine
Key to the concept design is
its inverted-V engine array,
with each turbine inlet
engineered to produce a low
boom noise output.
