Structural optimization of composite helicopter rotor blades
Işık, Alperen Ayberk; Kayran, Altan; Department of Aerospace Engineering (2018)
Structural optimization of a helicopter rotor blade with uniform aerodynamic surface and twist at the functional region is performed for weight minimization subject to various constraints relevant to helicopter rotor blades. The genetic algorithm based optimization is performed only for the functional region of the blade. Design variables are taken as the number of unidirectional S-glass layers in the spar cap, position of the spar web with respect to the leading edge, nose mass diameter and position of the...
Structural optimization of composite and aluminum horizontal tail plane of a helicopter
Arpacıoğlu, Bertan; Kayran, Altan; Department of Aerospace Engineering (2019)
This thesis presents structural optimization studies of aluminum and composite material horizontal tail plane structure of a helicopter by using MSC.NASTRAN optimization capabilities. Structural design process starts from conceptual design phase, and structural layout design is performed by using CATIA. In the preliminary design phase, study focuses on minimum weight optimization with multiple design variables and similar constraints for both materials. Aerodynamic load calculation is performed using ANSYS ...

Structural monitoring and analysis of steel truss railroad bridges
Akın, Tuğba; Türer, Ahmet; Department of Civil Engineering (2012)
Railroad bridges are the most important connection parts of railroad networks. These bridges are exposed to heavier train loads compared to highway bridges as well as various detrimental ambient conditions during their life span. The railroad bridges in Turkey are mostly constructed during the late Ottoman and first periods of the Turkish Republic; therefore, they are generally close to about 100 years of age; their inspection and maintenance works are essential. Structural health monitoring (SHM) technique...
