Students aid
in research
of propellers
By KEVIN S. INDA
Reporter
The current widespread use of jet
engines on aircraft might be re
placed soon by a modernized pro
peller concept, says Dr. Kenneth
Korkan, a Texas A&M professor of
aerospace engineering.
Several aerospace engineering
students at A&M are helping with
the propeller concept, he said.
The aviation industry has begun
to seek better fuel efficiency due to
rising costs, Korkan said, and the
new propeller systems are more fuel
efficient and can develop the same
type of velocity as a jet engine.
“One type of propeller system we
are working on is the counter-rotat
ing propeller,” Korkan said. “This
system involves one propeller turn
ing one way and the other propeller
turning the other way.”
This type of propeller system has
two propellers with one placed in
front of the other. Both propellers
have six blades and turn in opposite
directions, he said.
Another benefit of the counter
rotating propeller system is that it
can be used in the military, he said.
A surveillance plane with this new
type of propeller can reach an area
quickly. Once the plane reaches a
designated area it can turn off one
of the propellers to save fuel, Kor
kan said.
Even though the new type of pro
peller systems are more fuel efficient
and develop the same amount of ve
locity as a jet engine, a few problems
still are associated the new systems,
Korkan said.
“Noise is the biggest problem,”
Korkan said. “This new system is as
noisy as a turbofan, but it’s a differ
ent type noise.”
Korkan said once the source of
the noise is identified, it can be elimi
nated by making different noises
cancel themselves out.
The research conducted by seve
ral graduate aerospace engineering
students is dealing with the testing of
acoustics in a counter-rotating sys
tem to find ways to reduce cabin vi
bration, Korkan said.
Before the students could test the
noise levels of the system they had to
build a model propeller test rig. This
model test rig is one of only a few in
universities or industry, Korkan
said.
The model propeller test rig was
built with parts “bought off the
shelf’ and through a combination of
efforts, Korkan said.
“The distinct feature about this
rig is the fact that it can individually
monitor the front and rear blades,”
Korkan said.
Korkan said he expects to see the
counter-rotating propeller system
widely used in the aviation industry
within 10 years.

GOP picks up 17 seats
in Texas House, Senate
—— -r —

brag Wednesday that the
tive movement has finally
United Press International
AUSTIN — Republicans gained a
crucial 16 seats in the Texas House
and picked up one seat in the Sen-
)ting state GOP officials to
conserva-
finally found its
way to the statehouse.
One incumbent Democratic sen
ator lost a re-election bid, 13 Demo
cratic House incumbents were de
feated and three previously
Democratic districts without incum
bent candidates switched to the
GOP. Every Republican legislator
who sought re-election was success
ful.
“The smashing triumph of the
president and Phil Gramm was ob
vious to all, but there was a lot more
that took place last night that means
something for the long-range future
of the Republican Party in Texas
and of the conservative movement,”
state GOP Chairman George Strake
said at a news conference.
Strake said voters’ dissatisfaction
with Democratic lawmakers who ap
proved a $4.6 billion tax increase last
summer — the biggest tax hike in
Texas history —was a “significant”
factor in the GOP’s 17-member gain
in the Legislature.
The House’s previous 113-37
edge for the Democrats dropped to
97-53 after Tuesday’s election.
Since many crucial procedural
votes in the House require a two-
thirds majority, the Democrats’ fail
ure to retain at least 100 seats in
creases the chance that partisan vot
ing will block major legislation when
the next legislative session convenes
in January.
“It virtually gives us a veto power
on all legislation that comes down
the pipe,” Strake said.
In the Senate, the GOP’s one-seat
gain also gives the upper chamber its
only female member. Cynthia Tay
lor Krier, a political novice and a for
mer aide to retiring GOP Sen. John
Tower, ousted 20-year legislative
veteran Bob Vale by a resounding 61
percent to 39 percent margin in a
traditionally Democratic district in
San Antonio.
Krier’s victory decreased the
Democratic edge in the Texas Sen
ate to 25-6.
Incumbent Democratic Sen. Ted
Lyon of Mesquite fought off a strong
showing by Richard Harvey of
Tyler, squeaking out a win with 50.5
percent of the vote.
The two other contested Senate
races saw wide-margined wins by in
cumbent Democrat John Montford
of Lubbock over Republican Sol
Thomas and Democratic state Rep.
Gonzalo Barrientos over GOP chal
lenger Pat McNamara in the race to
fill the seat vacated by unsuccessful
U.S. Senate candidate Lloyd Dog-
gett.
Ninety-five incumbents in the
150-member House and 10 new
comers faced no opponents on
Tuesday’s ballot, while 11 incum
bent senators had no opposition.
Sixteen incumbents in the 31-mem
ber Senate are not up for election
until 1986.
Eight incumbent House members
— all Democrats — lost primary
bids.
Other Democratic incumbents de
feated Tuesday include: Hill Kemp
of Manvel, losing to Jack Harris of
Pearland in District 27; Bill Harrison
Jr., losing to Ted Roberts in Corpus
Christi’s District 36; Bob Barton of
San Marcos, losing to Anne Cooper
in District 47 in Central Texas; Russ
Tidwell, losing to Bob Richardson in
Austin’s District 49; and Tip Hall of
Denton losing to Ben Campbell of
Lewisville in District 61.
