Consul Haynes Gives a Description OF
French Airship.
Consul Haynes reports from Rouen.
France, July %, In regard to the prize Of
fered by Mr.. Henry Deutsch to promote the
development of aerial navigation. Mr.
Deutsch placed at the disposition OF the
Aero Club $4,000, to be given to the ex-
perimenter who, starting from st. Cloud.
should in half an hour double the Eiffel
tower and return.
The consul describes the attempt of Mr..
Santos-Dumont, a young Brazilian, to win
the prize. Many well-known authorities in
France, Mr.. Haynes says. have pronounced
this the most important development in
aerial navigation. His balloon Is described
as follows:
It is a cigar-shaped cylinder Ill feet long,
10 feet in diameter and 600 cubic yards In
volume. 1t has fOur-cylindered petroleum
motor of sixteen horse power; a propeller
screw measuring Ii feet from blade edge
to blade edge, and making 200 revolutions
per minute, and traction power, measured
by the dynamometer, OF 16O pounds To
give the cigar-shaped structure sumcient
rigidity to cleave the air there is placed
within it smaller balloon, which Is sup
piled with air by an aluminium yentilator,
the volume varying with the altitude, keep
ing the exterior balloon constantly stiff.
Below the balloon hangs a sort Of trian-
gular framework fifty-nine feet long, con-
sisting of three curvilinear wooden scant
lings joined with aluminium and strength
ened by crosspieces of wood and a network
of piano wire. AT twenty-three feet from
one extremity Of this light framework, in
the center of the triangular section, the
motor is suspended by piano wire. At
distance Of twenty-three feet from the
other extremity Is situated the little basket
car In which the aeronaut takes his place
and where he controls the arrangements
for lighting the motor. for starting the
screw propeller, for working the rudder,
controlling the escape valves and regulat-
ing the displacement of the guide rope from
one end to thes other, by means of fne
cords This displacement Of the guide rope
Is meant TO incline the balloon in the direc-
tion that may be required for ascending or
descending. The framework. with It's mo-
tor and the aeronaut's car, Is suspended
from the balloon by steel wires Of such
tenuity that they are invisible at q distance
In the trial on July 1s, adds the consul.
there were two conditions with which Mr..
Santos-Dumont failed to comply. The air
ship did not accomplish the journey inside
Of thirty minutes and did not come to the
earth at the starting point The journey
was made in forty-one minutes, at an aver
age speed OF about thirteen miles an hour.
Each year the authors OF projects win be
allowed to prove the practicabilfty Of their
apparatus. All machines must be manip-
ulated by the competitors at their own ex-
pense and risk. II the prize is not won
within five years. beginning April 15. 1900.
the offer Of Mr.. Deutsch win be null. Until
some one succeeds In gaining the prize he
VIII turn over to the committee OF the Aero
Club each year 1000 francs GT7O. for dis
tribution among those most deserving OF
encouragement.
