ARMY A|RMEN TEST
NEW. TYPE PLANES

BY JOSEPH 5. EDGERToN.

DAYTON, Ohio, August 22.-The
military defenses Of the United Staaes
may be iatrusfted to airplanes or revo-
Iutionary types never before seen in the
Army service squadrons Il tests now
In progress or soon to be made at
Wright Field, Dayton. Ohio, the mate
rel division base, of the Army Air
Cofps, are successful.
The two-seater pursuit planes of
terrific offensive and defensive power,
observation planes which viii outclimb
any now in the service. three scatter
twin-engined reconnaissance planes of
long range, great speed and high cell
ing; light bombers of dazzling speed
and low-wing attack monoplanes re-
sembling somewhat the type OF plane
Charles A. Lindbergh and Capt. Frank
Hawks are among those to face the
rigid tests Of the Materiel Division,
engineers and pilots. -
The first two-seater. pursuit plane
was delivered here yesterday and will
be ready for testing fight as soon as
q new type Of motor adapted TO the use
of ethylene glycol cooling fluid is in
stalled. The plane which is expected
to be as fast and Is. maneuverable as
many Of the single seaters now In the
service was built by the Berlmer- Joyce
Aircraft Corporation, in Baltimore.
Though it will carry two men and twice
the number Of guns, 1t will have but
little more than the wing surface of
the present singIe-seater pursuit plane,
depending upon high speed and great
power for the necessary lift, The sec
ond man will occupy rear cockpit
and man movable guns to protect the
vulnerable blind spot which Is the
greatest weakness of the present pur-
suffer.
Tests OF Plane Completed.
Flight and service tests have been
completed Of q two-seater observation
! plane possessing great power and ,url-
usually fast climbing ability. This
plane IS of the O-25 series, built by
bougiass and powered with 6o0-horse-
power Curtiss conqueror engine, with a
propeller gearing ratio Of i've TO three
for added power. Approximately 20 of
these planes ARE to be delivered to the
observation 'sQuadrons.
The material division soon will re-
ceive for testing one OF the most
unusual planes vet built for the Army,
twin-engined flying wing which viii
be tested both for long range recon-
naissance and for fast light lombard
ment. It Is Fokker powered with
two 600-forsepower Curties engines
stream-lifed into the wings. The
fuselage also u built into the wing and
the landing wheels, located beneath the
engines, may be drawn up in flight to
cut down resistance. High speed, fast
rate OF climb and the ability to ny miles
above the earth's surface are expected
Engineers Of the nateriel division also
are considering o low-wing nionoplane
of great speed for attack purposes or
ground stra6ing. Some Of the paper
work has been completed and further
studies are In progress rs q result OF
the sensational speeds obtained by
LtndberRh, HAWKS and others with
planes OF the low-wtng type. The pro-
posed Army plane would combine ex-
celient visibility with high speed, espe-
ciniiy with m inverted engine Of the
v-type, It ID believed.
Langley Planes on Today.
The present attack planes are biplanes
with speeds of 1856 miles per hour or
less, despite which they are regarded
as the most powerful engines Of war
yet developed for use against ground
troops, guns and transport columns.
They mount six machine guns each and
Nine Keystone borabardment planes
OF the second bonbardment group,
Langley Field, va, held here yesterday
by bad weather, were to continue to-
day to Chicago TO participate in the
National AID Races. In these planes
the crack pilots Of three Of the Arny's
most famous botnbardment squadrcns,
under command OF Capt. Henry Pas
Gale, win demonstrate the latest methods
Of Commandment attack and defense
against hostile aircraft.
