No Time for Theorilinp

No Time for Theorizing
one Of the chief rules outlined At
the beginning of the DESIGNING u,o,,.
was that no engineer should be nor.
mltted to introduce constrnction
which had not been tried out There
was no time for theorizing. The new
engine is successful because il en-
bodies the best thought of enqipear
ing experience to- date Not only did
Ihis country furnish ideas through
celebrated consulting engineers hnt
the representatives in the United
states OF England, France. and Italy
co-operated in the development Of
this motor.
lhlrty days after the assembling
OF the first engine preliminary tests
JUSTIFIED the government in formally
accepting the engine as the best air
craft engine produced in any country
The final tests confirmed our faitn
IN the new motor in every degree.
Both the flying and altitude tess
oil the new motor have been sYatffv-
ing. One test was conducted AT
Pixies Peak, where the United States
aviation engine performed satisfact-
orlly at this high altitude. One of
the engines, in an airplane, broke the
American altitude record in a recent
flying test.
While it is not deemed expedient
to discuss in detail the performances
and mechanics of the new motor. it
may be said that Standardization IS
chief factor in the DEVELOPMENT of
the governments motor. Cylinders.
pistons, and every other part of the
motor have been standardized. They
may be produced rapidly and eco
nom ically by great many factories
operating under government con-
tracts. They may be as rapidly as
sembled, either by these plants or
at a central assembly plant
The new engine amounts prac-
tically to an international model. /.
embodies the best there is in Amer
lean engineering and the best features
OF European models so far as it has
been possible to adapt the latter to
American manufacturing methods.
Had Every Available US. Suggestion
The two engineers most directly
connected with the production of the
United States aviation engine had be-
fore them not only the blue prints
and models of the most successful en-
gines the war has produced but also
every available American suggestion.
Men skilled in the invention of mot
ors, both automobile and airplane
advised these engineers who were
charged with The duty of provid ,ng

would embOdy every essential for
war time use. Non-essential COM
pleXities were consistently discarded
by these engineers. The result was
composite design OF maximum
power. minimum weight, great speed
capability, and adaptabilty TO quick
production.
The standardization of parts ma
terially simplifies the problem of re-
pair and maintenance Spare parts
will be promptly available at all
tim es. Even the cylinders are de-
signed separately. 1t is possible to
build the new engine in four models,
ranging from four to II cylinders,
and under the Standardization plan
now worked out an eight-cylinder
or a 12-cylinder model can be made,
using the same standard cylinders,
pistons, valves, cam shafts, and
SO on.
Question of Rapair Simplified
This will make the question OF
repairs back of the lines compare
lively simple matter. The parts of
wrecked ight-cylinder or 12-cylinder
engines will be interchangeable, and
new engine may be assembled from
the parts of wrecked machines
THE Standardization of the new
engine does not mean there will be
no change in it during the war.
