NEW WEAPON HAS
2OO-MILE RANCE
Scientist Invents ProieotiIe Which
Can Rise to Height of Sev-
enty Miles.
NEW THING IN BALLISTICS
Propelled by Powder-Fed Engine
Deadly Gas or Explosives Borne
In It's Head and One Man
Can Discharge It.

Worcester, Mass.-A rocket MS an
agent Of warfare over land or sea, hav-
Ing a perpendicular range of 20 miles
and a horizontal range of 200 miles or
more, ana capable Of carrying power
ful charges of explosives or deadly
gases has been invented here by Or.
Robert II. Goddard, professor of phys
les at Clark college.
In his experiments, which he an
nounced have attained success, he had
The cooperation and worked by tie au-
thority of the war department and the
Smithsonian institution in Washington,
and Clark university and the Worces-
ter Polytechnic institute. Compared
with it, the most powerful implements
Of modern warfare are rendered inef-
fectiye, scientists familiar with the in
vention assert.
Under the system of propulsion
worked out by Doctor Goddard the
rocket could rise to height above the
earth's atmosphere, where its range
would be increased greatly.
It's propulsive power-which Mill
taly men say is a new contribution to
the science of balllstlcs-lles in an in
ternal combustion engine Of high pow
er, fed either by finely pulverized
smokeless powder or charges of liquid
explosive at regular intervals regulated
by clockwork. Experiments with min
iatWe models conducted here have
fully demonstrated its success against
an enemy.
Can Be Fired Without Cannon.
Instead of requiring a cannon or
mortar to start it, one man from any
spot can launch it without apparatus.
The destructive agency is in the head
Of the rocket though it can be adapted
for Photographic work as well, the ap-
paratus being automatically released
from the rocket proper and descending
With parachute.
In the rockets simplest form, manu-
factured at small cost, foot soldier
would become the equivalent of a
field cannon for a single shot for he
would carry on his shoulder an instru-
nent of destruction, with its head of
gas or high explosive, and fire it from
my point where his legs would take
aim. And that would often be where
cannon could not be moved.
For a simple, quick maneuver
thousand men might discharge thou
sand rockets, each the equivalent OF
| 3-inch shell, from firing positions
lot easy to locate and quickly evacu-
tied. Or 10000 or 100000 rockets
night be placed in position unknown
o the enemy, each in its simple firing
rough, and wired together in electri-
al circuits, to be exploded after every
nan had left the place, by the closing
Il n circuit
Worked Under Guard
Doctor Goddard worked on the de-
of his invention from the
ime the United States went to war.
Armed guards stood watch day and
light and the vicinity was illuminated
o that no one could spy on the inven-
or in the darkness.
Doctor Goddard's rocket has an out
r cylindrical shell of thin metal, at
he lower end of which is the combus-
ion chamber having relatively thick
walls Of nickel steel and opening d-
ectly at the lower end into an out
.ardly tapering nozzle, exactly like !
he nozzle OF a gas turbine. The open
ne from the combustion chamber into !
he nozzle is of much less diameter |
han the chamber itself The pressure !
developed by the explosion Of the cart |
idge in the chamber is enormous and !
he increasing diameter of the nozzle |
,ermits Of the utilization OF the ex-
iansion Of the gases. The function
# combustion is "speeded up" so to
peak. The result is a high degree Of |
efficiency. Velocity, and therefore
ange, Increases proportionately as
ompared to the present standard
