Tank will allow
simulation of
21-foot waves
Simulation of up to 21-foot
ocean waves, currents of up to
two knots and wave lengths of
up to 500 feet are now available
in a three-dimensional wave-sedi
ment basin here.
“We have the only wave tank
of any magnitude in the South
and Southwest,” said Dr. John B.
Herbich, head of the Civil Engi
neering Department’s Coastal and
Ocean Engineering Division.
The 32-foot by 86-foot by 2.5-
foot basin is located in the uni
versity’s Hydromechanics Labora
tories next to the new $9 million
Engineering Center.
Recently place in operation, the
tank will be used to perform har
bor and estuary model studies,
wave refraction and diffraction
problems and coastal sediment
littoral drift and erosion.
Currently, Herbich’s staff is
running a model study of offshore
dredging systems.
Funding for the basin came
from Chicago Bridge and Iron Co.
It contains tide and portable wave
generators and water supply lines
to generate the currents.
The tank holds approximately
41,170 gallons of water, Herbich
said.
Texas A&M began its coastal
and ocean engineering program in
1968 at the graduate level, and
Herbich said an undergraduate
program will begin within two
years.
The first research paper from
the wave tank program was pre
sented last month at the Offshore
Technology Conference in Hous
ton.

Texas air plan study continued
A $385,118 contract for con
tinued research to develop an air
transportation plan for Texas has
been awarded to the Texas Trans
portation Institute.
Jack Keese, TTI director, said
the research is being conducted
under an interagency agreement
with the Division of Planning
Coordination of the Office of the
Governor in cooperation with the
Texas Aeronautics Commission.
TTI’s contract is part of a
$419,974 grant from the Federal
Aviation Administration of the
Department of Transportation to
the state. It is supplemented by
the state for an estimated $630,-
000 to cover the further develop
ment of a comprehensive state
wide airport system. The work is
to be done over a 27-month period.
The TTI research is for Phase
II work which involves the draft
ing of an airport system plan and
will include an inventory of exist
ing airports, their usage, and an
analysis of future needs. The
study will forecast future aircraft
demand and provide an examina
tion of passenger and cargo needs
in the state.
It also will establish an airport
system plan for Texas that in
corporates inputs from other
regional systems plans as they
are developed.
The air mode is seen as an im
portant element in over-all trans
portation planning for continued
development of market areas,
movement of goods and people,
and communication throughout
the state, Keese said. It is recog
nized also for its major impact
on the fast-growing metropolitan
areas of the state where com
mercial carriers provide inter-city
service.
Student explains danger
of wing-generated 6 twisters 9
Miniature tornadoes which shed
off wing tips of in-flight airplanes
are becoming dangerous.
All aircraft produce wing tip
vortices, a Texas A&M student
notes, hut the spiraling columns
of air generated by big airplanes
such as the Boeing 747, the
French Concord and Russia’s TU-
144 are vicious.
Carlos M. Barrera said in a
study of the phenomena that the
big planes leave behind “twisters”
which pose a distince danger to
smaller following aircraft. Struc
tural failure and life loss are
possible.
“Giants such as the Concord
and B-70 have vortex velocities
as high as one and a half to two
times the flight speed of light
planes,” the areospace engineer
ing major from San Antonio re
ported.
Barrera noted in a report to
Dr. C. A. Rodenberger that Fed
eral Aviation Administration of
ficials are trying to make general
aviation pilots aware of the pres
ence and danger of the vortices,
and how to avoid them.
Barrera worked in a Texas
A&M Flight Mechanics Labora
tory experiment to learn more
about wing tip vortices. Investi
gation conducted by Dr. W. P.
Jones and Dr. B. M. Rao made
the vortices visible and measur
able. Smoke bombs attached to
the wings of a Beechcraft T-34
and a 20-foot tower revealed the
air flow as a sinusoidal (a con
tinuous “S” shaped) curve.
As the curve dissipated in calm
air, puffs of smoke marking in
dividual air swirls formed at reg
ular intervals, Barrera said. They
lingered over the runway 20 to
30 seconds. If the bottom of the
curve touched the runway, it
broke up quickly.
Barrera, who completed his
aero engineering studies this
spring, noted that FAA reports
“vortices formed at 30,000 feet
where airliners cruise remain in
tact, complete with high velocity
winds around the core of the
vortex.”
They fall at 500 feet per min
ute and level off 700 to 900 feet
below and behind the generating
plane’s flight path. The vortices
caused by the 747 may be 60 feet
in diameter and encountered 35
miles behind the aircraft that
caused them. As one form of clear
air turbulence (CAT), they can
cause structural damage to planes
flying through them.
Vortices produced by big planes
landing and taking off lie over
the runway. Some have taken 160
seconds to clear out.
The phenomenom is caused by
the slightly arched airplane wing,
designed to create lift by gener
ating lower pressure on the up
per surface as the wing moves
through the air.
“Pressure differences between
the top and bottom of the wing
disappear gradually toward the
wing tip,” explained Barrera, a
San Antonio Highlands High
School graduate. “These pressures
do not match at the tips, causing
a flow of air from the bottom to
the top—from greater pressure to
lower pressure. Because the wing
is moving forward, this tip air
flow is shed as vortices.”
Barrera offered three solutions.
Heavy vortex generators might
be restricted to flying certain
zones and special airports. Or,
wing loading restrictions might
be placed on future aircraft con
struction, limiting their size. He
said it might be possible to de
sign an airfoil which would re
duce vortex strength.
