Estimating gaseous emissions production of an entire flight of a commercial aircraft based on emission measurements and actual flight data records
(Deutschen Forschungsanstalt fur Luft-und Raumfahrt, 2015)
In this study, engine emissions measurement results and actual flight data records are used to obtain an emissions production profile of gate-To-gate flight activity. The platform and pow- erplant selected arc B737-800 and ...
Environmental assessment of a micro turbojet engine with the aid of exergy
(American Institute of Aeronautics and Astronautics Inc, AIAA, 2016)
Environmental impact of the aviation industry has been an important issue in last decade. In order to decrease the environmental effect and to improve the efficiency of aero engines, one needs to understand the performance ...
Model Derivation, Attitude Control and Kalman Filter Estimation of a Quadcopter
(IEEE, 2017)
Recently unmanned aerial vehicles have become one of the most interesting research topics among scientists. Although researchers are very concerned in this area, they generally use the same dynamical plant equations. ...
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, ...
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. ...
Emission Benefits of Continuous Descent Approach
(World Scientific And Engineering Acad And Soc, 2009)
The approach phase often has the most fuel savings potential among the other phases such as takeoff, climbout, cruise and ground operations. Therefore, the main objective of this study is to investigate being close to the ...
Calculation of NOx Emissions of Short and Medium-haul Domestic Flights with Consideration of the Ambient Effect
(IEEE, 2017)
In this study, NOx emissions of typical flights at two domestic round trip routes (206-271 NM and 625-740NM) are quantified. The flight and engine parameters were obtained from actual flight data records, whereas the ...
Application of thermodynamic laws on a military helicopter engine
(Pergamon-Elsevier Science LTD, 2017)
By definition, a turboshaft engine is simply a gas turbine used to deliver shaft power such as to a helicopter rotor. This paper presents the energetic and exergetic analyses of a turboshaft engine which is used for military ...
