. Jtiwiowskl, says It Is ready I
lor a heavy research program that
E

will include Htudies on types of
ittrpluneB nulically different from
those now neon in tho nlr.
. Tho controversy over the rein- 1
live efficiency of monoplnncs and
multiplanes is far from ended, ac
cording to Professor Pawlowskl j
who believes that tho monoplane's '
present popularity !s a transitory j
whim of designers. He nnd an iih-
sociate, U. V. Kerber, plan further .
research with multiplanes in the !
new Michigan wind tunnel.
"The monoplane is well adtipted :
to tho present stage of tiir trans
portation," Professor Ptiwlowskl
fays, "but when airplane designers j
are called upon in future years to
construct trans-oceanic planes big .
enouph to carry hundreds of peo
ple, the multiplanc
uirplane with three,
more wing surfaces appears to
otter greater possibilities."
Kerber already has carried on
some experiments in (he Michigan
wind tunnel during the last three
years with a uuadrupltinc having
four wings sets back In tiers above
each other. The model, developed
to perfect scale of a full-sized ma
chine, proved to have high lift ef
ficiency and other characteristics
favorable to operation.
Experts lu , the industry recog
nize that the universities must be
depended upon for development of
i u.ure aeronautical engin e e r s.
Kerodynamics and other special
ized subjects in which the aero
nautical engineer must have thor
ough training probably can be
taught with greatest ease and-efficiency
through competent uni
versity instruction.
Wind tunnels, which are the
laboratories for research in aero
dynamics a highly technical field
embracing the study of airplanes'
flight properties have a romantic
appeal to the popular imagination.
They make It possible to study
exactly how an airplane will act in
winds of velocities up to several
hundred mites ah hour, without
ever building the full-sized air
..pliijic... Toy-like models, built with groat
accuracy and precision, are used.
Delicate wires suspend the models j
in the tunnel air stream, and sen- j
sitive instruments record the j
forces acting upon the model n,x
if it were in flight.
Tho fnivi'rsity of MU-hignn wind
tunnel. designed by Professor
Pawlowskl, differs from most oth
ers at university, military and
eommercinl aeronautical Inborn- j
torles. ' I
It has a dun! return for the air
blown through the main throat of
the tunnel, so that the air circu
lates constantly instead of being
blown out one end. It also has a
unique arrangement which makes
, possible an adjustment of the tun
nel's throat to diameters of ffvo,
six, seven or eight feet. This
makes possible flexibility In its use
for research problems involving
nil-streams of various velocities up
to 250 miles an hour.

With all makes of cars on display with the improvement
for 1929 a matter of record it must be plain to everyone
that the new Buick with Masterpiece bodies by Fisher
merits final recognition as the most advanced automobile
of the day! . . , . .
Its arresting new body lines and contours stamp it im
mediately as the newest and most distinctive motor car atyle.
Its new Valve-in-Head six-cylinder engine is not only the
most powerful automobile engine of its size in the world
but the leader in getaway, swiftness and stamina as well.
Moreover, a host of new luxury factors make the new Buick
the most comfortable automobile to ride in and to drive.
Scores of thousands of buyers have recognized these facts
and entered orders for the new Buick during the past five
months. And scores of thousand of others are acclaiming
Buicks advanced quality at automobile displays:
throughout the country. . . . :
Every comparison proves the new Buick an outstanding
value as new and unrivaled today as the day it appeared!
