Abstract
Pengembangan desain turbin yang dilakukan berkembang pesat, salah satunya dengan metode analisis beban dinamik secara computational fluid dynamic (CFD) yang menerapkan prinsip interaksi antara fluida dengan struktur. Kerusakan yang terjadi pada turbin merupakan hal yang tidak diinginkan karena menyangkut performansi turbin. Umumnya kerusakan ini terjadi berupa keretakan atau patah pada turbin. Oleh karena itu pada tugas akhir ini dilakukan analisis pengaruh variasi material dan struktur blade terhadap beban dinamik straight blade cascaded, sehingga pada penelitian ini akan didapatkan desain blade yang optimal. Dari analisis yang telah dilakukan didapatkan bahwa kombinasi struktur-material hollow-carbon fiber merupakan desain struktur pada blade yang baik berdasarkan parameter deformasi yaitu sebesar 0,8 mm. Namun apabila melihat parameter stress dan strain struktur material solid-e glass FRP merupakan desain blade yang terbaik yaitu maksimum stress/strain yang dihasilkan sebesar 17848,8 MPa.

The development of turbine design has grown fast, this method use dynamic load analysis in computational fluid dynamic (CFD) which is used the principle of interaction between fluid and structure. Damage to the turbine is undesirable because it involves turbine performance. Generally, this damage occurs in the form of cracks or broken turbines. Therefore in this final project an analysis of the effect of material variation and blade structure on the dynamic load of cascaded straight blades is analyzed, so that in this study an optimal blade design will be obtained. From the analysis that has been done it was found that the structural combination of hollow-carbon fiber material is a good structural design for blade based on the deformation parameters of 0.8 mm. But when looking at the stress and strain parameters of the solid- e glass FRP material is the best blade design with the maximum stress-strain value at 17848,8 MPa.
