Work on an anti-stall device for
neral aviation aircraft is in prog-
at Texas A&M University.
n 8 sl )' Research directed by Howard
teadt-ievalier, Texas A&M aerospace
arcln igineering professor, will soon
ive to wind tunnel testing of a
l-scale aircraft equipped with a
iler-type stall prevention system,
its will be conducted at Langley
search Center facilities in
nia. The studies will involve
jr aerospace engineering majors
Faulkner of Bryan and Bruce
of La Feria.
Sevalier and students ran similar
ests in the Langley tunnel last
mer.
Full-scale flight tests are planned
Inext fall.
They are expected to produce a
irevention system applicable to
jralpurpose airplanes for the Na-
al Aeronautics and Space Admin-
tion. NASA funds the research.
Stall and aircraft spins that fre-
uently occur after a stall are the
^st single cause of aviation death
^injuries.
Stall occurs when a plane goes into
high angle of attack attitude and
!s airspeed. Airflow separates
h the top of the wing, causing a
[of lift.

Chevalier has worked on a stall
evention device since he joined
eTexas A&M faculty in 1969. His
rly efforts were unfunded but were
tei backed by the Federal Aviation
ministration,
nldkvt fhe system consists of a vane or
er attached to a plane s control
ices. An altitude sensing device
activates a servomotor to deploy the
vane or spoiler, preventing stall.
The system has been test flown on
single and twin-engine aircraft and
demonstrated in flights at several na
tional aerospace engineering confer
ences.
“NASA wants a more up-to-date
system, in a ‘small black box’ of three
by six inches, for installation near
appropriate control surfaces,”
Chevalier said.
“We hope we will also get the
aerodynamics of the plane at high
angles of attack to see what effect the
system has, he said. “At that point,
we will have a stall-proof plane and
want to know what its aerodynamics
are, now that they are in a range
non-predictable according to
theory.’’
From those numbers, Chevalier
added, it should be possible to work
backwards and “see what the
geometry of a stall-proof plane is.
That’s my goal, to achieve a stall-
proof general aviation plane by its
geometric configuration, rather than
by add-ons.”
He said that such geometry would
radically alter the appearance of air
craft. Major changes would appear
in wing and tail design, said the
former NASA research engineer.
“Having a stall-proof general avi
ation airplane would increase its
utilization by allowing a pilot more
freedom, Chevalier said.
“About one in five persons go past
their first flying lesson,” Chevalier
said. “Approximately one in 10 con
tinue past a private license. For
some, the reason is money. But we
don’t know how much is stress. If we
can take away pilot fear that is inad
vertently built in with instruction
(he’s told never to get his plane in a
stall situation), the increase in gen
eral aviation would be marked.”
Runaway hippo holding out
United Press International
IRVINE, Calif. — Bubbles was
alive and well Tuesday and still
eluding Lion Country Safari ran
gers who are confident they can
return her safely to her 800-
pound daughter at the wild ani
mal park.
Rangers tried to fire tranquiliz-
ing darts into the two-ton hip
popotamus during the night but
were unsuccessful. Bubbles, who
escaped from captivity Feb. 19,
remained submerged in a lake.
“Bubbles is alive and well,”
said park spokesman Jo Schetter
shortly after dawn.
Pickets protesting reports
Bubbles might be killed had
created crowd control problems
which Mrs. Schetter said actually
endangered the hippo’s life.
“The rangers are going to have
to shoot to kill if she endangers
humans,” she said. “The best
thing they can do for Bubbles is to
stay away from the area. We can
bring her home if given time and
no interference from outsiders.
We have the trained manpower
to bring that hippo in alive.”

Coast ofthe United States, and in the
Caribbean. Next year the Texas
A&M team plans to examine the
floor of the Pacific.
“The sea floor is under constant
change,’ said Schink. “Mud, bac
teria and a variety of marine or
ganisms play an important part in
mixing, filtering and turning over
the ocean floor. The sea bed acts as a
filter. We are interested in the rate
these organisms in the mud stir the
sea floor.
The atomic age and nuclear testing
has provided the Texas A&M re-
serachers a means for measuring the
sea floor’s mixing or filtering rate,
said Schink.
“By bomb testing, man has spread
a small trace of plutonium across the
land and oceans,” said Schink. “Us
ing radioactive sensing equipment,
we can measure the amount of
plutonium on the ocean floor.
“Mud accumulates very slowly. If
there were not mixing, the
plutonium would lie just on the sur
face of the ocean bed. By looking at
the plutonium below the surface, we
have a way to measure the rate of
stirring. In 25 years, the traces of
plutonium have been sifted some 10
centimeters into the ocean floor.
The actual rate and depth varies
around the world, but one of the
higher ratings we have found is
around the mouth of the Mississippi
River. “

While you're working on your degree, you're also working toward a
commission in the Air Force. After graduation and commissioning,
you'll enter active duty, and discover a whole new world,
You'll find challenge, responsibility, a demand for your talents, and a
high regard for what you're contributing. There's more. As an officer in
the Air Force you'll have an excellent salary with a full slate of benefits.
Look into AFR0TC scholarships. And while you're at it ask about the
Air Force way of life. You’ll discover more than just a way to make your
finances come out while you're in college. You'll discover a whole new
world of opportunity.
