Reliable Overspeed Protection For Industrial Drive Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
The paper discusses the fundamental relationships between turbine overspeed and the time constant of the rotor. The amount of overspeed is shown to be related not only to the time lag of the emergency tripping devices, but ...
Developments In Multiple Fuel Applications For Gas Turbines
(Texas A&M University. Gas Turbine Laboratories, 1973)
As the decade of the 1970's gradually unfolds, it becomes clear that it will be a decade of challenge for many of you who are engaged in the Process, Pipeline, or Electric utility Industries. The changing 11orld supplies ...
Optical Alignment Of Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1973)
Optical alignment is a technique which has proven its usefulness in original installation, repair and maintenance of turbomachinery. Optical alignment, sometimes referred to as optical tooling utilizes precision optical ...
Compressor Performance, Field Data Acquisition And Evaluation
(Texas A&M University. Gas Turbine Laboratories, 1973)

(Texas A&M University. Gas Turbine Laboratories, 1972)
This paper deals with the new developments in compressor aerodynamics. The emphasis in this paper is on the various aerodynamic developments that have led to better compressor performance. An outline of a new technique to ...
Commissioning A Gas Turbine-Compressor Single Lift Package For Offshore Gas Reinjection Applications
(Texas A&M University. Gas Turbine Laboratories, 1972)
Sixteen centrifugal stages in two cases driven by a Rolls Royce AVON jet and a single stage power turbine compress natural gas of Mol Weight 23 from a pressure of 65 to 2000 psia. The rotating train, the coolers, the ...
Selection And Application Of High Speed Gear Drives
(Texas A&M University. Gas Turbine Laboratories, 1972)
This will be an exploration of the relevant factors involved in successfully applying gear drives to high speed rotating machinery. Relationships of internal design features to external equipment and couplings is defined ...
Present Instrumentation And Future Trends In Real Time Analysis Equipment
(Texas A&M University. Gas Turbine Laboratories, 1972)
In the past instrumentation available to the diagnostician for analysis of machinery problems was limited to swept narrowband filter systems and, less important, parallel narrowband filter systems. Although useful for ...
New Technology In Turbine Aerodynamics
(Texas A&M University. Gas Turbine Laboratories, 1972)
This paper presents a cursory review of some of the recent work that has been done in turbine aerodynamic research at NASA-Lewis Research Center. Topics discussed include the aerodynamic effect of turbine coolant, high ...
High Speed Journal And Thrust Bearing Design
(Texas A&M University. Gas Turbine Laboratories, 1972)
There are many approaches to the design of thrust and journal hearings for high speed turbomachinery, ranging from the simplest flat thrust bearings and plain journal hearings to the very sophisticated multiwedge designs ...
