Exergetic sustainability assessment of a HALE UAV using dodecene fuel
(Inderscience Enterprises LTD, 2016)
Exergetic sustainability performances of a high altitude long endurance (HALE) unmanned aerial vehicle (UAV), having a single turbofan engine and using dodecene as its fuel were investigated all along its flight profile, ...
UAV path planning using segmented cellular evolutionary algorithm
(Inderscience Enterprises LTD, 2016)
Path planning is one of the most important issues for sustainable development of unmanned aerial vehicles (UAVs). The aim of the path planning is to provide the shortest and safest route. In this study, an algorithm has ...
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 ...
Using some performance parameters to predict exhaust gas emissions of a turboprop engine: adaptive neuro-fuzzy method
(Inderscience Enterprises LTD, 2016)
This paper presents an exhaust gas emissions prediction model for a turboprop engine depending on some performance parameters. Within this context, experimentally collected emissions data is used to develop a model in the ...
New Model for the Optimization of Runway Orientation
(Asce-Amer Soc Civil Engineers, 2014)
One of the most significant factors that affects the location of airport elements is the optimum runway orientation. In this study, a new model called Calculation of Optimum Runway Orientation (CORO) is developed with an ...
Empirical analysis of the effect of descent flight path angle on primary gaseous emissions of commercial aircraft
(Elsevier Sci LTD, 2018)
In this study, the effects of descent flight path angle (between 1.25 degrees and 4.25 degrees) on aircraft gaseous emissions (carbon monoxide, total hydrocarbons and nitrogen oxides) are explored using actual flight data ...
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. ...
Operating Temperatures of the Solar Cells Used in the Concentrator System With Radiating Plates
(Turkish Soc Thermal Sciences Technology, 2016)
A solar cell concentrator system is offered to satisfy the energy requirement of the satellites orbited around the Earth. The solar cells coupled to the system are exposed to sunlight concentrated 124 times with a Cassegrain ...
Energetic and exergetic efficiency modeling of a cargo aircraft by a topology improving neuro-evolution algorithm
(Pergamon-Elsevier Science LTD, 2016)
An aircraft is a complex system that requires methodologies for an efficient thermodynamic design process. So, it is important to gain a deeper understanding of energy and exergy use throughout an aircraft. The aim of this ...
Designation of Environmental Impacts and Damages of Turbojet Engine: A Case Study with GE-J85
(MDPI, 2014)
Between the troposphere and stratosphere layers of the atmosphere is a critical zone for collecting emissions and negative effects on the Earth (ecological, humanity, and resources). Aircrafts are the main causes of the ...
