Henry Farman, who began his flying career with a Voisin machine,
evolved from it the aeroplane which bore his name, following the
main lines of the Voisin type fairly closely, but making alterations
in the controls, and in the design of the undercarriage, which was
somewhat elaborated, even to the inclusion of shock absorbers. The
seven-cylinder 50 horse-power Gnome rotary engine was fitted to the
Farman machine--the Voisins had fitted an eight-cylinder Antoinette,
giving 50 horse-power at 1,100 revolutions per minute, with direct
drive to the propeller. Farman reduced the weight of the machine from
the 1,450 lbs. of the Voisins to some 1,010 lbs. or thereabouts, and
the supporting area to 450 square feet. This machine won its chief fame
with Paulhan as pilot in the famous London to Manchester flight--it is
to be remarked, too, that Farman himself was the first man in Europe to
accomplish a flight of a mile.
Other notable designs of these early days were the ‘R.E.P.’, Esnault
Pelterie’s machine, and the Curtiss-Herring biplane. Of these Esnault
Pelterie’s was a monoplane, designed in that form since Esnault
Pelterie had found by experiment that the wire used in bracing offers
far more resistance to the air than its dimensions would seem to
warrant. He built the wings of sufficient strength to stand the strain
of flight without bracing wires, and dependent only for their support
on the points of attachment to the body of the machine; for the rest,
it carried its propeller in front of the planes, and both horizontal
and vertical rudders at the stern--a distinct departure from the Wright
and similar types. One wheel only was fixed under the body where the
undercarriage exists on a normal design, but light wheels were fixed,
one at the extremity of each wing, and there was also a wheel under the
tail portion of the machine. A single lever actuated all the controls
for steering. With a supporting surface of 150 square feet the machine
weighed 946 lbs., about 6.4 lbs. per square foot of lifting surface.
The Curtiss biplane, as flown by Glenn Curtiss at the Rheims meeting,
was built with a bamboo framework, stayed by means of very fine
steel-stranded cables. A--then--novel feature of the machine was the
moving of the ailerons by the pilot leaning to one side or the other in
his seat, a light, tubular arm-rest being pressed by his body when he
leaned to one side or the other, and thus operating the movement of the
ailerons employed for tilting the plane when turning. A steering-wheel
fitted immediately in front of the pilot’s seat served to operate a
rear steering-rudder when the wheel was turned in either direction,
while pulling back the wheel altered the inclination of the front
elevating planes, and so gave lifting or depressing control of the
plane.
