© 2020 The Authors. Published by Elsevier B.V.Water jet guided laser overcomes the adverse effects of conventional laser cutting and drilling processes, such as heat-affected-zone, spatter, burr formation, etc. Pressurized water in this novel process provides focusing, cooling and cleaning on the cut region, eliminating undesired side effects of the laser. The process is nowadays used in energy and aerospace industries for drilling micro cooling holes on turbine blades made of super alloys. However, more re...

In this paper, a new multiploid genetic optimization method handling surrogate models of the CID solutions is presented and applied for multi objective turbine blade aerodynamic optimization problem. A fast, efficient, robust, and automated design method is developed to aerodynamically optimize 3D gas turbine blades. The design objectives are selected as maximizing the adiabatic efficiency and torque so as to reduce the weight, size and cost of the gas turbine engine. A 3-Dimensional steady Reynolds Average...
Multi objective conceptual design optimization of an agricultural aerial robot (AAR)
Özdemir, Segah; Tekinalp, Ozan; Department of Aerospace Engineering (2005)
Multiple Cooling Multi Objective Simulated Annealing algorithm has been combined with a conceptual design code written by the author to carry out a multi objective design optimization of an Agricultural Aerial Robot. Both the single and the multi objective optimization problems are solved. The performance figures of merits for different aircraft configurations are compared. In this thesis the potential of optimization as a powerful design tool to the aerospace problems is demonstrated.
Multibody simulation of helicopter rotor with structural flexibility
Özturan, Bali İhsan; Kayran, Altan; Department of Aerospace Engineering (2019)
Most of the multibody simulation tools used for modeling helicopter rotor use beam models of the blade and the rigid rotor hub. Stress recovery in the blade and in the hub are then performed by means of cross-sectional analysis tools or finite element analysis tools. In this study, multibody model of a helicopter main rotor is established using three dimensional flexible models of the blade and the rotor hub, and multibody simulations of the rotor are performed for the hover and the forward flight load case...
