Performance Evaluation of Simple Aero Gas Turbine Cycle with Transpiration Cooling of Gas Turbine Blades
Aero gas turbine engines have been using mainly film cooling and convection cooling techniques. For operating at high gas temperature amongst different cooling options the transpiration cooling technique has emerged as the most promising technique to improve the gas turbine cycle performance by allowing higher turbine inlet temperatures. This paper investigates the advantages of transpiration c...
متن کاملAircraft Gas Turbine Engines Technical Condition Identification System
In this paper is shown that the probability-statistic methods application, especially at the early stage of the aviation gas turbine engine (GTE) technical condition diagnosing, when the flight information has property of the fuzzy, limitation and uncertainty is unfounded. Hence is considered the efficiency of application of new technology Soft Computing at these diagnosing stages with the usin...
متن کاملTesting and Condition Monitoring of Composite Wind Turbine Blades
In a wind turbine system, blades are one of the most critical components. They capture energy from wind and convert it to a mechanical energy for electricity power generation. However, once the blades are defective, the power generation efficiency of the turbine will be significantly affected. In worse case when the blade is seriously damaged, the turbine will have to be shut down completely fo...
متن کاملSimulation of Mist Film Cooling on Rotating Gas Turbine Blades
Film cooling technique has been successfully applied to gas turbine blades to prevent it from the hot flue gas. However, a continuous demand of increasing the turbine inlet temperature to raise the efficiency of the turbine requires continuous improvement in film cooling effectiveness. The concept of injecting mist (tiny water droplets) into the cooling fluid has been proven under laboratory co...
متن کاملNew Technologies for Modeling of Gas Turbine Cooled Blades
In contrast to existing methods which do not take into account multiconnectivity in a broad sense of this term, we develop mathematical models and highly effective combination (BIEM and FDM) numerical methods of calculation of stationary and cvazistationary temperature field of a profile part of a blade with convective cooling (from the point of view of realization on PC). The theoretical subst...
