Energy, exergy, and exergoeconomic analysis of a general UAV
(Inderscience Publishers, 2023)
A 3E - energy, exergy, exergoeconomic - analysis of a rotary wing UAV that is used for general purpose has been accomplished in this study. In the study, a parametric investigation regarding the velocity, altitude and ...
Virtual Investigation on the Response of Glare to Low Velocity Impact
(Institute of Electrical and Electronics Engineers Inc., 2023)
Due to the increasing cost of experiments and the increased time required to complete the experimental process, it is more economical to conduct experiments in the form of virtual tests. Therefore, low velocity impact ...
Obtaining the Fracture Resistance Curve Using the General Displacement
(Kauno Technologijos Universitetas, 2023)
In this paper, the energy release energy corre-sponding to the unit crack propagation obtained from the displacement-controlled load-displacement plot is equalized to the elastic energy release rate, and the variation of ...
The modified residual property model for fracture mechanics
(Kauno Technologijos Universitetas, 2023)
In this paper, the application requirement of the Residual Property Model based on the decrescent exponential function is reduced to only one mechanical test datum. For this, by using Creager , Paris's elastic stress field ...
Conceptual design and optimal sizing of a small unmanned aerial vehicle with fuel cell and battery-powered hybrid propulsion system by meta-heuristic algorithms based on energy consumption
(Taylor and Francis, 2023)
In this paper, a new conceptual design methodology for a hybrid propulsion system consisting of the battery and hydrogen fuel cells is presented based on the minimum energy consumption of the UAV. In this context, an ...
A new hybrid meta-heuristic optimization method for predicting UTS for FSW of Al/Cu dissimilar materials
(SAGE Publications, 2023)
Joining of aluminum (Al) and copper (Cu) materials used in aerospace, automotive, chemistry, nuclear, electrical-electronic and energy sector with traditional fusion welding methods has some negative consequences. One of ...

(Emerald Publishing, 2023)
PurposeThis study aims to systematically compare the effect of increasing fiber-matrix interface adhesion and matrix toughness in layered composite materials. Design/methodology/approachSilane ((3-glycidyloxypropyl) ...
Simultaneous UAV having actively sweep angle morphing wing and flight control system design
(Emerald Publishing, 2023)
Purpose: The purpose of this paper is to improve autonomous flight performance of an unmanned aerial vehicle (UAV) having actively sweep angle morphing wing using simultaneous UAV and flight control system (FCS) design. ...
Frequency-dependent electrical parameters and extracted voltage-dependent surface states in Al/DLC/p-Si structure using the conductance method
(Springer, 2023)
In the present work, a diamond-like carbon film (DLC) was electrodeposited on a p-Si substrate and was used to fabricate an Al/DLC/p-Si/Au metal/interlayer/semiconductor (MIS) Schottky diodes (SDs). The structural analysis ...
A monostatic RCS reduction study for an antenna in structural mode at X band
(Taylor and Francis, 2023)
In this paper, a radar cross-section (RCS) reduction of a microstrip antenna is investigated both experimentally and numerically. A traditional metal ground plane antenna and a bandstop frequency selective surface (FSS) ...
