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, ...
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 ...
