Fuel flow-rate modelling of transport aircraft for the climb flight using genetic algorithms
(Royal Aeronautical Soc, 2015)
In this study, development of a new fuel flow rate model for the climbing phase of flight was achieved using a genetic algorithm (GA) method. Two modelling approaches were performed using real flight data records (FDRs) ...
Simulation modelling of runway capacity for flight training airports
(Royal Aeronautical Soc, 2014)
This study aims to develop a practical discrete-event simulation model to analyse the single runway capacity of airports serving training flights under various operational scenarios. The number of operations per hour, ...
PRN Code Correlation in GPS Receiver
(IEEE, 2017)
Satellite based positioning systems like GPS (Global Positioning System) exist in every moment of our lives. GPS signal is broadcasted by Link1 (L1) and Link2 (L2) frequencies, separately. L1 is assigned to civil users, ...
Aircraft Engine Sensor Fault Detection, Isolaton and Reconfiguration Using Fuzzy Logic Control Based Unknown Input Observer
(European Turbomachinery Soc-Euroturbo, 2013)
In this paper, a model-based robust fault diagnosis approach 'Unknown Input Observer (UIO)', 'Generalized Observer Scheme (GOS)' and 'a Fuzzy Logic Control Mechanism' will be studied respectively for fault detection, ...
A machine learning model to predict NOx emission for turbofan engines of commercial aircraft during idle condition
(Advanced Engineering Solutions, 2016)
A machine learning modelling approach to predict nitrogen oxides (NOx) emission was accomplished for turbofan engines of commercial aircraft during the idle condition utilizing International Civil Aviation Organization ...
Investigating the exergetic and environmental effects of subcooling and superheating processes on the performance of direct expansion systems
(Springer International Publishing, 2014)
Recently, subcooling and superheating applications, which are proposed as an approach for the efficient use of energy, have positive effect on the emission next to increasing the energy efficiency. This study examines ...
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. ...
An Integrated Navigation System Design For Quadrotors
(IEEE, 2015)
In this work, a particle filter based integrated navigation system is designed and tested with real quadrotor systems. Conventionally, Kalman filter based algorithms is used for navigation systems which is highly non-linear. ...
