The author examines the potential of the gas turbine in alleviating air pollution as a replacement for presently used vehicular reciprocating engines. Automobiles receive particular emphasis because of the magnitude of their contribution to the problem. Emissions of gas-turbine engines are compared with those of gasoline reciprocating engines, and other important characteristics relevant to the problem (such as engine power output, reliability, transmissions, vehicle performance, fuel consumption, and manufacturing cost) are discussed. It is concluded that widespread adoption of vehicular gas-turbine engines can — provided these engines can be produced and operated at costs competitive with those of future reciprocating engines — can virtually eliminate automotive air pollution as a source of serious environmental concern.

Abstract The use of inlet air fogging installation to boost the power for gas turbine engines is widely applied in the power generation sector. The application of fogging to mechanical drive is rarely considered in literature [1]. This paper will cover some considerations relating to its application for gas turbines in ship drive. There is an important evaporative cooling potential throughout the world, when the dynamic data is evaluated, based on an analysis of coincident wet and dry bulb information. This data will allow ships’ gas turbine operators to make an assessment of the economics of evaporative fogging. The paper represents an introduction to the methodology and data analysis to derive the direct evaporative cooling potential to be used in marine gas turbine power output loss compensation.

Turbine cooling, originally developed because of a shortage of heat-resistant alloys, is of interest for certain applications to permit operation of gas-turbine engines above uncooled temperatures. Specific power output would be increased, and in some cases specific fuel consumption decreased, depending on the engine type. Progress is reported on developments since 1952.

The current contribution of gas turbine engines to air pollution is small. Improved control of emissions from other sources, increased use of gas turbines, and changes in gas turbine emission characteristics may cause the air pollution contribution of gas turbines to become more significant. A laboratory model gas turbine combustor was used for investigation of the internal burned gas composition. Of particular concern was nitric oxide. It was found that nitric oxide concentration is controlled by the kinetics of its formation. Evidence of the chemical kinetic behavior of carbon monoxide and unburned hydrocarbons also was obtained.

The article contains the results of the metrological examination and research of the accuracy indicators of a method for diagnosing aircraft gas turbine engines of the D30KU/KP family using an ultra-high-frequency plasma complex. The results of metrological examination of a complete set of regulatory documents related to the diagnostic methodology, and an analysis of the state of metrological support are provided as well. During the metrological examination, the traceability of a measuring instrument (diagnostics) – an ultrahigh-frequency plasma complex – is evaluated based on the scintillation analyzer SAM-DT-01–2. To achieve that, local verification schemes from the state primary standards of the corresponding types of measurements were built. The implementation of measures to eliminate inconsistencies identified during metrological examination allows to reduce to an acceptable level the metrological risks of adverse situations when carrying out aviation activities in industry and air transportation. In addition, the probability of occurrence of errors of the first and second kind in the technological processes of tribodiagnostics of aviation gas turbine engines is reduced when implementing a method that has passed metrological examination in real practice. At the same time, the error in determining ratings and wear indicators provides acceptable accuracy indicators and sufficient reliability in assessing the technical condition of friction units of the D-30KP/KP2/KU/KU-154 aircraft engines.

Prospects Of Application

The paper gives a brief review of properties and applications of developed extra-hard nanostructured composite materials and coatings based on them. The presentresearch suggestsaerospace applications of nanostructured composite materials based on carbides, carbonitrides and diboridesof transition and refractory metals. To improve the technical and economic performance of gas turbine engines, it is advisable to use new composite structural materials whose basic physicomechanical properties are several times superior to traditional ones. The greatest progress in developing new composites should be expected in the area of materials created on the basis of polymer, metal, intermetallic and ceramic matrices. Currently components and assemblies of gas turbine engines and multiple lighting power units with long operation life and durability will vigorously develop. Next-generation composites are studied in all developed countries, primarily in the United States and Japan.
