To Gauge Speed Spectrum
AEROSPACE RESEARCH FACILITY
Dr. Richard Thomas examines a 10-foot section of shock
tube under construction in the Gas Dynamics Lab. Effects
of shock waves will be studied in the 12-inch, 20,000 volt
facility when it is finished this spring. Thomas, an asso
ciate professor of aerospace engineering, designed the tube.

Texas A&M soon will offer
velocity research labs from
“cloud hopper” to spacecraft
speeds.
The Space Technology Division
is constructing a 12-inch shock
tube, in which aerodynamic pro
cesses of entry into a planetary
atmosphere will be simulated.
The atmosphere of earth, Mars
or Venus can be reproduced in
it.
When tube operations begin
this spring, A&M will have test
facilities for the extremes of
man’s speed spectrum. The Gas
Dynamics Lab shock tube dupli
cates 5,000 to 35,000 miles per
hour conditions.
The seven-by-ten foot wind
tunnel at Easterwood Airport
has a speed range to 200 miles
per hour.
“I know of no university which
has the facilities we will have at
A&M,” declared Dr. Richard E.
Thomas, architect of the $100,000
facility and associate professor
of aerospace engineering.
A&M’s shock tube is one of
only two in the state or South
west that is electrically driven.
To “shoot” the tube, 200,000
joules of electrical energy are
discharged at 20,000 volts into
a “driver.” The current, stored
in 70 shielded capacitors, arcs
between electrodes across a heli
um-filled space.
Pressures up to 15,000 pounds
per square inch generated by
rapid heating of gas in the 2.5
inch diameter by 10 inch “driver”
chamber ruptures an “x” scored
diaphram and releases into the
40-foot long tube.
Shock waves are formed like
those caused by X-15 rocket
planes and Gemini space cap
sules re-entering the earth’s at
mosphere.
Passage of the wave super
heats an “atmosphere” placed in
the tube from bottles of nitro
gen, carbon dioxide and argon.
Superheated “air” immediately
behind the wave will move at al
most the speed of the wave, ion
ize and undergo chemical change.
Among items studied, Thomas
said, are magnetohydrodynamics,
and plasma, heat transfer and
radiation, wakes, interaction of
shock waves and chemical effects
on gases.
Models can be inserted into the
12-inch tube for study.
After each “shot”, which will
sound like a shotgun being fired,
the chamber and tube must be
cleaned, a new diaphragm in
stalled and the apparatus evacu
ated by two pumps.
Pumps remove air from the
tube to conditions equivalent to
150,000 to 250,000 feet of all
tude.
“Reloading” requires about)
minutes, Thomas calculate)
Charging capacitors takes fm|
minutes.
Highly sensitive instrument!
are inserted into the half-iatl
thick aluminum tube in porfer
spaced at three-foot internfe
along its length. One insta
ment spectroscopically analyze
the 10,000-degree heated gas.
“We hope to attract reseattl
support,” Thomas comment*!
“and continue to expand ourfi
cilities. But the lab will be uiti
primarily to support our mag
mission, giving the youth of Tin
as the finest aerospace engineer
ing training in the country.”
16 Education Majors Finish
Student Teacher Training
Every semester a new group
of students enroll in the student
teaching program offered by the
Department of Education and
psychology.
Such a group is now complet
ing its 18-week period of on-the-
job teacher training. With the
cooperation of local school sys
tems 16 students were able to
encounter the actual experiences
of teaching prior to the time
when they will be in complete
charge of a class themselves.
The students teach classes in
their specific fields under the
guidance of a fully qualified and
experienced full - time teacher.
They are assigned to classes aft
er their own capabilities and spe
cialties are carefully reviewed.
Dr. William Stokes, director
of student teachers, is responsi
ble for matching the student,
class and teacher who will super
vise the student teacher. He is
