Comparative Evaluation Of Investigation Methods For Estimating The Load-Dependent State Of Charge And End Of Discharge Of A Multirotor Uav Battery, Hanna Dibbern, Morten Roßberg, Claudia Werner
Comparative Evaluation Of Investigation Methods For Estimating The Load-Dependent State Of Charge And End Of Discharge Of A Multirotor Uav Battery, Hanna Dibbern, Morten Roßberg, Claudia Werner
Journal of Aviation Technology and Engineering
As the scope of multirotor unmanned aerial vehicle (UAV) applications increases, more attention is being paid to UAV energy requirements, which vary depending on the mission profile. To obtain accurate information about the UAV battery during flight, the idea of a digital twin including a battery state estimation model is promising. For battery state estimation, a Kalman filter combination is the preferred approach in the literature. Comparing different Kalman filters, the unscented Kalman filter has a more accurate estimation for nonlinear systems compared to the extended Kalman filter. In the application of UAV flight with load-dependent flight missions, the comparison …

A Literary Survey On The Challenges Of Adopting Lean In Aerospace Production And Aviation Maintenance, Seanan C. Lee
Journal of Aviation Technology and Engineering
Lean production began as a new method for creating value through the elimination of waste, continuous process improvement by workers, and fostering respect for people. Despite its success in other industries, the significantly lower production volume, the substantially higher complexity, and the service-oriented nature of aviation maintenance demand significant adaptation of Lean principles to be effective. The lack of a holistic study on Lean adoption for aerospace production and aviation maintenance organizations hinders transformation as the two industries are intertwined in product and characteristics. Lean adoption in aerospace production is hindered by the lingering notion that it is an ‘‘automotive …
