Investigation of thermodynamic performance based on the humidity effect in the aircraft environmental control systems
(Inderscience Enterprises LTD, 2015)
Some environmental parameters, such as pressure, temperature, humidity and velocity, of air are important for passengers, stayed in aircraft cabin. These values change with altitudes, also atmospheric conditions. The ...
Exergoenvironmental analysis of piston-prop aircrafts
(Inderscience Enterprises LTD, 2012)
This study deals with exergoenvironmental analysis of a four-cylinder, spark ignition, naturally aspirated and air-cooled piston-prop aircraft engine for landing takeoff (LTO) and cruise phases. This analysis includes the ...
Assessment of thermodynamic and environmental performances in subcooling process for different refrigerants
(Inderscience Enterprises LTD, 2017)
Subcooling application in cooling processes leads to increasing of cooling performance and energy efficiency within defined limits. This study examines subcooling effects of refrigerants on the coefficient of performance ...
Assessment of a ramjet engine for different Mach numbers
(Inderscience Enterprises LTD, 2017)
The aim of this study is to determine optimum working of a generic ramjet engine. A thermodynamic analysis has been performed to evaluate three different ramjet flight conditions that have been obtained by using GasTurb. ...
Aero-propulsive modelling for climb and descent trajectory prediction transport aircraft using genetic algorithms
(Royal Aeronautical Soc, 2014)
In this study, a new aero-propulsive model (APM) was derived from the flight manual data of a transport aircraft using Genetic Algorithms (GAs) to perform accurate trajectory predictions. This new GA-based APM provided ...
A study of challenges to the success of the safety management system in aircraft maintenance organizations in Turkey
(Elsevier Science BV, 2015)
The ICAO is an international regulatory authority put in place, in addition to current prescriptive regulatory approaches based on regulatory compliance that use reactive tools, performance based approaches that focus on, ...
A qualitative study on the exploration of challenges to the implementation of the Safety Management System in aircraft maintenance organizations in Turkey
(Elsevier Sci LTD, 2015)
Safety management has recently started using a paradigm that 'sees the world as it is' rather than 'prescribing how it should be'. The Safety Management System (SMS), a product of this paradigm shift, has fairly new and ...
Automatic optimization of a centrifugal pump based on impeller-diffuser interaction
(SAGE Publications LTD, 2018)
In this study, a centrifugal pump has been optimized using the genetic algorithm coupled with computational fluid dynamics considering the flow physics for various impeller-diffuser configurations. During the automatic ...
Assessment of thermodynamic performance and exergetic sustainability of turboprop engine using mixture of kerosene and methanol
(Inderscience Enterprises LTD, 2016)
In this study, first and second laws of thermodynamics were performed in the turboprop and is analysed and discussed with the mathematical model of sustainability performance of a turboprop engine using a mixture of ...
Performance Evaluation of an Experimental Turbojet Engine
(Walter De Gruyter GMBH, 2017)
An exergy analysis is presented including design parameters and performance assessment, by identifying the losses and efficiency of a gas turbine engine. The aim of this paper is to determine the performance of a small ...
