The Aeroplane Speaks. Fifth Edition
·
H. Barber

The
Clement-Bayard
monoplane,
1911,
was
convertible
into
a
tractor
biplane.
The
standard
engine
was
a
50
h.p.
Gnome.
The
machine
was
interesting,
but
never
did
much.
The
Zodiac
was
one
of
the
earliest
to
employ
staggered
wings.
With
50
h.p.
Gnome
engine
it
was
badly
underpowered,
so
never
did
itself
justice.
The
Jezzi
tractor
biplane,
1911,
was
a
development
of
an
earlier
model
built
entirely
by
Mr.
Jezzi,
an
amateur
constructor.
With
a
low-powered
J.A.P.
engine
it
developed
an
amazing
turn
of
speed,
and
it
may
be
regarded
as
a
forerunner
of
the
scout
type
and
the
properly
streamlined
aeroplane.
The
Paulhan-Tatin
monoplane,
1911,
was
a
brilliant
attempt
at
high
speed
for
low
power;
it
presented
certain
advantages
as
a
scout.
A
50
h.p.
Gnome,
fitted
behind
the
pilot's
seat
in
the
streamlined
fuselage,
was
cooled
through
louvres.
The
propeller
at
the
end
of
the
tail
was
connected
with
the
engine
by
a
flexible
coupling.
This
machine
was,
in
its
day,
the
fastest
for
its
power
in
the
world,
doing
80
miles
per
hour.
Viking
1
was
a
twin
tractor
biplane
driven
by
a
50
h.p.
Gnome
engine
through
chains.
It
was
built
by
the
author
at
Hendon
in
1912.
Much
ingenuity
was
exerted
by
the
French
designers
in
1911
to
produce
machines
for
the
Military
Trials.
Among
them
was
the
100
h.p.
Gnome-Borel
monoplane
with
a
four-wheeled
chassis,
and
the
Astra
triplane
with
a
75
h.p.
Renault
engine.
This
last
had
a
surface
of
about
500
square
feet
and
presented
considerable
possibilities.
Its
principal
feature
was
its
enormous
wheels
with
large
size
tyres
as
an
attempt
to
solve
difficulties
of
the
severe
landing
tests.
The
Clement-Bayard
biplane
was
a
further
development
of
the
Clement-Bayard
monoplane;
the
type
represented
could
be
converted
into
a
monoplane
at
will.
The
Lohner
Arrow
biplane
with
the
Daimler
engine
was
an
early
German
tractor
biplane
built
with
a
view
to
inherent
stability,
and
proved
very
successful.
The
Pivot
monoplane
was
of
somewhat
unconventional
French
construction,
chiefly
notable
for
the
special
spring
chassis
and
pivoted
ailerons
at
the
main
planes;
this
pivoting
had
nothing
to
do
with
the
name
of
the
machine,
which
was
designed
by
M.
Pivot.
