PHILIPS FLYING MACHINE.

been made to solve the problem of aeri-
al navigation, the principle most in
favor of late years has been that of
large plane surfaces. Upon this princi-
pie for some twenty-eight years past
Mr. Horatio Phillips has worked until
at length he has succeeded In demon
strating that the principle Is funda-
mentally correct. But he has reduced
the dimensions of his planes from some
four or FIVE feet broad to those OF
Venetian blind laths, much to his ad-
vantage. His method of proceeding In
fact is entirely different from that
hitherto pursued by Others working
In the same field, as neither large plane
surfaces nor balloon arrangements are
employed, nor Is stored-up energy
used. Advantage Is taken of vacuum
and plenum is formed by induced
currents on the upper and under sur
faces respectively Of a series of Stats
or laths fixed horizontally In verti-
cal frame. These Stats are curved on
their upper and under surfaces and are
thicker at their leading edge than at
their trailing edge. The curves are such
! that the convex upper surface near the
front edge defects the air upward, thus
creating a partial vacuum on the up
under surface Of the slat is formed to
paribolical curve which gradually
puts the particles of air into motion
downward, thus producing an excess OF
pressure on the under surface of the
stats. The principle has been put into
practice by Mr.. Phillips In a machine
which broadly resembles a canoe with
sail like Venetian blind with the
Stats fixed wide open, the machine be-
ing driven forward by an air propeller
to which motion is given by steam
engine.
The carriage is 25 feet long and 1S
inches wide, tapering to a point at the
| front end. 1t is borne onS wheels a
foot in diameter, one in front and two
at the rear There are so sustainers or
Stats, each IL inch wide and % feet
long, fitted two inches apart in frame
| 20 feet wide and feet inches In
height. The sustainers have combined
aera of lifting surface of 1856 square
feet. The boiler is cylindrical phos-
| phor bronze vessel 10 inches In diameter
and 16 inches in length. The heating
surface Is 70 square feet. and is made
up of Field tubes 3-4 inch in diameter
and II inches long The fire crate area
Is 70 square inches, and the fuel used
Is Welsh coal. The engine is compound,
having cylinders ga inch by 3 5-S
inch by G inch stroke. fitted with or
binary slide valves. The working pres
sure of steam is 1870 ID per square inch.
| The propeller is 6 feet in diameter and
s feet pitch, and has a projected area
Of blade surface OF four snuare feet.
The speed is about 400 revolutions per
minute, and the estimated speed OF
the machine about 50 miles an hour.
| The weights of the various parts OF
the machine are approximately as fol-
lows: Carriage and wheels, 60 pounds;
machinery complete in working order
with water In boiler and fire on CRATE,
200 pounds; sustainers, 70 pounds; total
weight of machine, 300 pounds; total
weight, lifted and carried, including
70 pounds of added weight, 4O2 pounds.
In order to test the machine a wood
en- track 62S feet In circumference and
about six feet wide has been laid in
the gun-proving grounds of Messrs.
Cogswell G. Harrison, at Harrow, the
machine being tethered to central
post In some trials which we recently
witnessed a number Of runs were made.
with the result that speed Of 2S miles
an hour was attained. AS regards the
ascenslonal powers of the machine,
1t was shown that 1t had a lift OF
about three feet from the ground at
the rear. The rise reached It's maxi
mum when the machine ran in the
face Of the wind, and was ontinued
over about two-thirds of the track.
The machine was also moored by a
stern rope In which a dynamometer
was inserted, and on the engine being
run at full speed, the dead pull was rs
pounds. On the whole the machine is
one OF promise, and is certainly step
In advance In aerial navigation.--Iron
