A Parametric Study of a Piston-Prop Aircraft Engine Using Exergy and Exergoeconomic Analysis Methods
(Taylor & Francis Inc, 2015)
In this study, exergetic and exergoeconomic analysis methods are applied to a four-cylinder, spark ignition (SI), naturally aspirated and air-cooled piston-prop aircraft engine in the cruise phase of flight operations. The ...
Evaluation of aircraft descent profile
(Elsevier Science BV, 2016)
Point Merge System (PMS) is a new method for merging and sequencing arrival traffic flows. It consists of sequencing legs, merge point. PMS allows Continuous Descent Approaches (CDAs) which reduces environmental impacts ...
Design and flight test study of a VTOL UAV
(American Institute of Aeronautics and Astronautics Inc, AIAA, 2015)
The aim of this paper is to present the ongoing studies about design and fight testing of a fixed wing UAV which is able to take-off and land vertically. The UAV concept discussed in this study has three propeller engines. ...
Application of Artificial Neural Network (ANN) method to exergy analysis of thermodynamic systems
(IEEE Computer Soc, 2009)
Exergy is a way to sustainable development and may be defined as the maximum theoretical useful work, while exergy analysis identifies the sources, the magnitude and the causes of thermodynamic inefficiencies within each ...
Modeling current and emerging threats in the airport domain through adversarial risk analysis
(Routledge Journals, Taylor & Francis LTD, 2016)
Airports are critical infrastructures entailing intense human, commercial and economic activity. As such, they are preferred targets for criminal and terrorist groups, who are attracted by the promisingly high revenues ...
Refrigeration inventory based on CO2 emissions and exergetic performance for supermarket applications
(Elsevier Science Sa, 2012)
In this study, first energy and exergy analysis for supermarket cooling applications having high refrigerant capacity are examined and next, based on these analyses and different gases used. CO2 emission effect caused by ...
Exergoeconomic Environmental Optimization of Piston-Prop Aircraft Engines
(Taylor & Francis Inc, 2015)
In this study, exergy, exergoeconomic, exergoenvironmental analyses, and exergoeconomic environmental optimization are applied to a four-cylinder, spark ignition, naturally aspirated and air-cooled piston-prop aircraft ...
Effect of ammonia fuel fraction on the exergetic performance of a gas turbine
(Elsevier Science BV, 2018)
Decreasing of fossil fuels and increasing global warming lead researchers to find cheap and environmentally friendly alternative energy sources. In this regard, ammonia (NH3) is a widely used feedstock. This carbon free ...
Investigation of environmental and exergetic performance for coal-preparation units in cement production processes
(Pergamon-Elsevier Science LTD, 2012)
The main objectives of the present study are to perform energy and exergy analyses of a coal-preparation unit in a cement plant and investigate the effect of varying dead state (ambient) temperatures on exergy efficiency. ...
Flight control and flight experiments of a tilt-propeller VTOL UAV
(SAGE Publications LTD, 2018)
The purpose of this work is to present a study on the stability and control of an unmanned, fixed wing, vertical take-off and landing aerial vehicle. This airplane is driven by a fixed-pitch tilt-propeller system with the ...
