my name is bastien le francois I am
the first pilot of solar airship
and I like to walk in the woods
so you take it as we are all here
we’re going from here we’ll go to the forest
of meudon but by an afternoon of
the summer of 1884 then my time on the
tray by the fountain hard sin
descend after passing through the
beside the ponds of meudon and as long as we
there we are going to pass we will push up
the chalais pond you know where he
there is the hangar besides passing there
in front of these curious there is noise
I do not know you but I never
really perceived an activity last
and yet today we hear
voice
wait to see a little more from
the state him where there are not too many weapons
we get to perceive something a
huge envelope makes its 50 meters
long under which they suspend a
long wooden basket with one side
like a big rudder and to the other
end a wooden propeller to the
excess of the rest it looks like
to do four times the height of a man
in the nacelle two men and around
a small team and is working on
preparations it looks like they have almost
loose eto’o finish in an anti vote and
then 10
the airship rises slowly
once well to get beyond the summit
trees we see the lily get in
rotation the airships started to
move forward and away to the south until
to be masked by the treetops
we do not see it every day if you
do not believe your eyes reassures you he
there are others were less fair
above the milling observatory was
best placed to take the only
snapshot of this flight then our airship
he went south
but the ground crew and stay there but
I was expecting them to go
re going about their business
now he stays there he continues to
look at the sky in the east direction
part of anjouan
that is, a good good quarter
an hour later small agitation
again and then we hear a noise a
kind of buzzing whistles
just before the emergence of the airship
from behind the treetops
we see a big turn
go back down and come back to where
he had taken off this is August 9, 1884
this is the first time an aircraft
flying machines built by hand
of the man comes back to the place
of his takeoff
that day the man proved that he was
able to control a flight so for
understand the historical significance of
the event must begin with
understand that until then the direction
Flights have always been more or less
the wind is like a carpet
rolling on which we ride when we
take off and until then again the camps
free balloon ie we had
no other way than to leave
wear by the wind
more precisely by the winds because
according to the altitude we find the carpet
does not necessarily have the same
speed nor the same direction
so that leaves a whole field of
possible but it requires to deal with
the winds of the day be airship
precisely these powers to be directed
move on these treadmill
so that requires a thruster a
propeller and what the fact of what the
run a motor and energy
a fuel
so in this century of revolution
industrial engines I have a lot of
development on this side and in
decades before the theft of
meudon several inventors +0 let’s note
try solutions for
propelled their aerostat to the force
muscle first if so and machine
steamed
but this summer of 1884 it is a motor
powered by a battery that has
made it all possible
there we are in 1884 about fifteen years old
later there was another
development that appeared the engine to
well known explosion that works him
with a particularly light fuel
so that allows much more flights
long as the 23 minutes of the manon flight
commercial air transportation goes back to
that time in germany first and
then in the 20’s it’s downright
crossing the Atlantic which is
made possible by these machines there in
one to two days less than what is
was sailing at the same time
and we forgot the extraordinary
popularity that saab but these engines to
explosion they also gave birth
finally to aviation aviation then
pretty formidable development on any
the first half of the 19th and 20th
century
so that in the 50’s there are
more than twenty hours
to cross the Atlantic
so from that time on this
time there the airship was no longer the
best way to transport quickly and
far from large volumes quickly transported
far and a lot
a kind of always more finally that
was the guideline of
industrial developments of this
second half of a century team the
airships was rather slow bulky
and sensitive to the wind of blow they are
quite naturally found in the second
technical developments plan
I suggest you come back a little bit
about what I just said when you
bright sensitive to voluminous wind
obviously since it’s their volume that
by the Archimedean thrust allows them
to be in the air suddenly they are slow
you all walk in the water with
from water to the 2g so far it’s
galley then resists our advancement
another advanced another move
the air is the same it resists me but
when we are an airship we are
so much bigger we have so much
more surface than that resists and more
we advance quickly no longer that resists
just a reasonable record
but go slowly it can be a
asset too i’m not saying that because
I see the chronograph scrolls
but when it comes to looking through
example we see more things when we
stay in a balloon for a long time
the unique experience of a balcony on the
ultimately dominant world both is
perfectly integrated since the wind
wears you from which you become the wind
you are part of the landscape and you
browse at the same time how course
aliot is also for a balloon
go slowly
nothing easier
just do nothing and float
sensitive to the wind there is wind
yes because if we want to go on a
treadmill that goes fast it takes
to be able to run on
if we are not able to run there
just make sure they are
Slow enough that the treadmill
it slowly enough if you want
that I’m going to stick you can remove
there are small pieces of wood at the foot
from the top of the balloon if you remove 1
should re off
so you have to make sure that the carpet
rolling it slowly enough when
we prepare a flight by balloon on door
a particularly attentive attention
particularly fine to the conditions of
wind at the treadmill stack of this
day there and finally it was a bit like that
the greatest intelligence of men
of meudon I mentioned earlier
it was not only effectively
their technical innovation the stack the
engine is the young but it was the
use in suitable conditions
it was to know how to bring to the atmosphere
the attention needed for their
experiences going well and it’s been from
do it at that time where we
did not know much about how that
is going up there in the atmosphere a
little like me finally when I
started the balloon I did not know
still a lot to the science of
the atmosphere
L was
I was a student engineer at the time and
I was full of ideas
renewable energy industry
cleaner but I think I had
especially already me too the head in the
clouds is a succession of opportunities
to spend time precisely with these
machines there to start with the balloon
free me too I got my patent
hot air balloon pilot shortly before
engineering degree and very quickly very
quickly with a team of students
we wanted to want
fly an electric dirigible
a new kind
that is, we replaced the battery
electric manon by a few meters
square of solar panels and if one to
dirigibles also go able to carry
his pilot
it was a world premiere that gave
7 this machine 22 meters long
kilowatt about almost
as heavy of solar panels as
two drivers adapted from the panels
solar on an airship on a
aerostat besides whatever they are
inflated the others that poses some
number of technical questions but the
challenge for us too hold a lot in
the operating conditions since no
only you have to pay attention to
wind but in addition that must be done
watch out for the light but finally
pay more attention to his
environment it’s a little bit
trend of the early XXI century
especially in the industry of
transport network
it forces to design the machines in
more targeted function of what we want
make them do I take an example
imagine that I’m asking you to
carry 500 people to the other end
the world in less than a day
we immediately see a white cigar
dld new all along the surfaces to
the back if I ask you to go
look for a man in danger in the
Mountain
as the storm approaches the device
we see a rotor a small rotor to
the back a birdcage in the middle
we have all seen these machines there more or
Less far
if you ask to stay
a long time long over a
given place or so to go
deliver you are looking for a charge
bulky or heavy where both
above to a place where there is neither
roads neither airport nor pork nor network
river waterways
there it starts to ask good reflection
you start to know me you have
a vague idea of where I’m coming from
but the image is still less clear
is actually it’s so sobering
anywhere in the world that on this
current decade
several governments have devoted
funding for programs
manufacturers develop solutions
who have never been so safe
they want it today
let’s go back a little adventure there you
we see in test flight over
the plain of noise at that time the
men targeted a crossing of the
sleeve we did not cross the sleeve
but we still did with our
small airships photoelectric one
a dozen flights of scenes
up to one hour even over an hour
of flight all in closed circuit we too
and since that experience gained
during this adventure of
previous and next
today I invested in one of these
industrial programs I was talking about
just now I was talking to you all to
time
just before the possibility that offers
the balloons the aerostats to see the
world at once almost auch
above and inside
but precisely me if I spent two
son I chose to spend my time on
these machines there it is precisely for
to explore this vision of the world
this vision is no longer conquering but
welcomed this vision of quality and
not more than the amount before any one
know about it before
to invite one wipes one’s feet before
to enter aerostat
we take the time because we do not have
other choice to understand where is
what we settle in and we take
aware that this humility there can
we open a field of very possible
vast and very promising I invite you
to rethink it in four five years and
some you should see reappear
these placid silhouettes forgotten but
familiar thanks
