Between the time the Wright
brothers decided to fly and Lind-
berg 'demonstrated it could ef-
fectively be done by taking a jaunt
across the Atlantic, the University
had set up the first aeronautical
engineering course in the United
States leading to a degree under
the direction of Prof. Felix A.
The "flying bug" had not bit-
ten deeply then and students prov-
ed to be few-but as time pro-
gressed and air flight became an
accepted part of the American
transportation system, the aero-
nautical department mushroomed
in population.
TODAY THE department bus-
ties with activity and it is diffi-
cult, if not impossible, to recall all
the projects that student engi-
neers and faculty members have
engaged in during the past decade.
Research activity now ranges
from determining just how
streamlined the new Studebaker
actually is, to taking samples of
the earth's atmosphere at alti-
tudes of 250,000 feet and better.
The massive department located
in the East Engineering Bldg. with.
research centers at ,Willow Run
and a new hub planned for the
University's North Campus is di-
vided into four major fields of
Aircraft Structure, Aircraft Pro-
pulslon, Aircraft Design and Air-
craft Instrumentation constitute
the major training fields of con-
centration for engineers planning
to enter the aeronautical industry.
to train students not only in the
theoretical phases of air problems
but also in the practical applica-
tions of their learning. Upon gra-
duation most students are ready
to enter inta the industrial field
of airplane production-many stu-
dents snaring top posts in the in-
dustry after appropriate training.
Comparatively few students
remain in the Aeronautical De-
partment to work on a much
coveted PhD. In fact less than
a dozen engineers received their

PhD's at the end of the second
World War.
However, the number of gradu-
ate students in the field is com-
paratively high when matched
against other schools around the
country devoted to the same sort
of training.
The pressing desire on the part
of the Air Force for the most up-1
to-date air discoveries has brought
more and more students into the
graduate program offered in the

THE AIR FORCE has sent manyj
of its men to study here in order
to pick up valuable information
on guided missiles-one of the
many courses open to graduates.
However, as one of the grad-

point out, many of these stu-
dents must first be trained in
the rudiments of propulsion, an
integral part of aeronautical
With the rapid advance made
during the past few years on the
general stock of basic information
in aircraft a simple knowledge of
the mechanical workings on the
part of an engineer is no longer
sufficient in itself.
Intensive courses in physics and
chemistry as they relate to the
aircraft industry are now neces-
sary to continue the advancements
in the field.

RECENTLY, THE entire curri-
cula of the department was re-
vised to bring it up to date in or-
der to meet the requirements and
demands of practicing industry.
Now most students add to their
education by working in aircraft
industries during summer vaca-
Research projects continue to
be numerous. Perhaps one of
the most interesting is work be-
ing done on the construction of
wind tunnels.
One of the most noteable
achievements in this field was the
construction of a supersonic wind
tunnel built shortly after the war
which is capable of testing minia-
ture airplanes in conditions equal-
ing four times the speed of sound.

The tunnel's test section is only
8 by 13 inches.

ANOTHER problem being work-
ed on is the construction of a tun-
nel capable of changing speeds
drastically while a plane is being
tested. Still another tunnel is
nearing completion for the study
of low speed turbulence on air-
craft. The low speed wind tun-
nel has proven more difficult to
construct than the regular high
speed one.
This tunnel when completed
will be 5 by 7 feet and will be
used to study the effects of gusts

tural phenomena on planes in

wind currents circulating about

test rockets is also being con-
ducted by the department. Most
of the research involves develop-
ing a better combustion engine
to allow higher temperatures
and lower fuel consumption by
the rocket.

provides broad opportunities
for chemists, physicists
and engineers cooperating
on many prolilems.
For one thing, much Du Pont re-
search is fundamental, aimed at ad-
vancing scientific knowledge regard-
less of specific commercial objectives.
However, such research often sug-
gests new products.. . each with its
own challenging technical problems
which must be solved before com-
mercial production can begin. Solv-
ing these problems offers another
great field of work for teams of en-
gineers and scientists.
"Teflon" tetrafluoroethylene resin
is an example of this well integrated

For coatings, previous research
suggested dispersions-minute par-
ticles suspended in a liquid. After
much study, a team of technical men
learned how to suspend particles of
"Teflon" about 1/125,000 of an inch
in diameter. Then a commercial scale
process was devised. This develop-
ment made possible thin coatings of
"Teflon" and also a process for ex-
truding the material.
Meanwhile, another group discov-
ered how to successfully formulate
the new plastic into "Teflon" tetra.
fluoroethylene resin finishes and wire
The development of "Teflon" illus-
trates the close teamwork that is the
basis of research at Du Pont. But
this teamwork doesn't end with re-
search. Bringing the product to com-
mercial reality requires development
and design work by chemists and both
chemical and mechanical engineers.
Next month's Digest will feature in-
formation on the opportunities Du
Pont offers men interested in this
phase of making "better things for
better living... through chemistry."

During research on refrigerants,
the polymer was discovered and work
was begun to make it useful. The new
plastic had a remarkable combina-
tion of properties; temperature re-
sistance beyond the range of any
previous plastic, excellent electrical
characteristics, and the highest de-
gree of chemical inertness of any
commercial plastic.
