Americas progress in the conquest
of the air was disclosed at noon yes
terday, when the second annual aero
nautical show opened at the list Regi-
ment Armory, Park Avenue and Thirty
fourth Street.
The opening ceremony was conducted
by Brigadier General William Mitchell,
of the United States Air Service, late
chief of aerial operations in France.
Among prominent civilians who at
tended was Thomas D. Ryan, chief Of
the aircraft production bureau during
the war.
The show itself is of commercial
character in its exhibits There are
displays Of various types Of pleasure,
passenger and freight carrying air.
planes that have been developed by the
country's aeronautical genius during
the year succeeding the signing of the
armistice. They visualize Americas
bid for the future aerial-carrying trade
of the world.
Scarcely had the show opened when
the first sale was made, when G. R.
Cullman and Joseph Murphy, of
Jersey City, purchased one of the three
passenger biplanes of the Oriole type,
shown at the Curtiss exhibit. The air
plane will be delivered Wednesday, and
the purchasers announced their inten-
tion of starting Immediately fight
to Tulsa, Okla, by way Of Washington.
d. c., and Atlanta, Ga. During the
flight they will take aerial photographs
of the country.
Need Adequate Landings
Mitchell said: "The Second Annual
Aeronautical Show marks an epoch in
the aviation development in the United
States. 1t marks the beginning Of the
consideration of commercial aviation
in a class especially by itself. The
problem OF commercial aviation to my
mind is: How may we utilize the air
will be able to compete with means of
transportation used on the ground?"
General Mitchell then emphasized the
need of the immediate development of
adequate landing grounds throughout
the country These, he said, were as
necessary to aviation as tracks were to
railroads, good roads to automobiles
and harbor facilities to ships. He said
engines should be specialized upon for
Improvement, and the structure of the
airplane itself should be modified, par
ticuarly with regard to various safety
devices.
On the question of improved airplane
engine design, General Mitchell said:
1.-THE turbo-booster is very interesting
because in way it may be the begin
nlng of an actual gasolene turbine en-
glne. 1t utilizes the exhausts from the
engine, which are delivered to a tur-
blne. This turbine rotates at q speed
or 22O00 revolutions q minute, and in
turn actuates an air compressor which
delivers this air to the carburetor at
high attitudes. In this way the power
OF an engine may be maintained at
high attitudes"
Although lacking the impressive
army and navy exhibits that were
feature of last years show, the exhib-
tion Of aviation this year is a great
success, despite the fact that the show
is rather cramped for space on the
armory floor In one corner is the new
giant mail-carrying airplane christened
the Owl by it's manufacturer. the L.
w. F. Corporation.
This giant machine. weighing a total
OF ten tons, dwarfs all else in the show
1t has just been completed and is still
to make its first flight. Beneath it's
mammoth wings are shown two models
of the new aerial "Rivvers" known as
the Butterfly also made by the same
firm. The Owl shows remarkably clean
lines for such a huge Ship" 1t has
three bodies-two of the fuselage type,
which terminate in the tail of the ma
chine, and smaller central body Of
the nacelle type. In the nose of each
of the three bodies there Is installed a
