“…Additionally, the authors such as Guo et al [12] investigated an aerobatic aircraft wing box and obtained a minimum weight optimal structure by optimizing the parameters of the wing skin and spar web. Monroy Aceves et al [13] developed a material and design selection methodology using a small low air-speed wind turbine blade case which comprised uniform thickness shin and a unidirectional reinforcement. In terms of shin thickness and reinforcement area, a wide design space was made to select an optimum design.…”

Structural design of composite stiffened panel for a flat wing micro-aircraft

In this study, the integral micro-sized composite wings are designed and manufactured by using carbon fiber reinforced plastics and low-density foam. The analytical expressions of bending stiffness of a multilayer sandwich structures for variable cross-section panel are determined. The obtained analytical bending stiffness is numerically verified using results of compressive buckling modes on wing panels from a numerical FE program and experimental tests by a series of stiffened structures which are empirically designed. Contrastive results demonstrate that the stiffener configuration tremendously affects the global buckling of the wing panels and the shapes, locations and intervals of the stiffeners which should be adjusted to construct a structure with maximum bending stiffness. Finally, with the use of the bi-directional evolutionary structural optimization method, the optimum design of the wing cross-section was determined by topology optimization method to pursue the best weight/stiffness. Compared with the initial structure, the optimum material layout of the topology structure performs better at reducing stress concentration and improving load carrying capacity of wing panels.

“…Monroy Aceves et al [ 224 ] have produced a methodology for material selection and design, that combines properties of the material with results of non-linear finite element analysis of the model, based on aerodynamic forces. The solutions are then reduced down based on specific selection criteria to choose an exact design.…”

The purpose of this paper is to provide a high level, holistic overview of the work being undertaken in the wind energy industry. It summarises the main techniques used to simulate both aerodynamic and structural issues associated with wind turbines and farms. The motivation behind this paper is to provide new researchers with an outlook of the modelling and simulation landscape, whilst highlighting the trends and direction research is taking. Each section summarises an individual area of simulation and modelling, covering the important historical research findings and a comprehensive analysis of recent work. This segregated approach emphasises the key components of wind energy. Topics range in geometric scales and detail, ranging from atmospheric boundary layer modelling, to fatigue and fracture in the turbine blades. More recent studies have begun to combine a range of scales and physics to better approximate real systems and provide higher fidelity and accurate analyses to manufacturers and companies. This paper shows a clear trend towards coupling both scales and physics into singular models utilising high performance computing system.

“…Therefore, the balance between the structural strength and total weight of blade becomes a concern. A methodology was presented for the structure design inside blade (Monroy Aceves et al, 2012). A program with graphical user interface (GUI) for materials selection and parameters adjustment was devoted to explore the best solution of blade structure that satisfies the design constrains while reducing the blade mass.…”

This paper presents the development of an integrated computer program for blade design of small to medium wind turbine generators. Since the blade design process is time consuming and recursive, an integrated computer program with combination of aerodynamic and structural considerations is developed to make the entire design process faster and more efficient. In this software package, there are five embedded sub-functions, including an aerodynamic coefficient generator, an airfoil database, an automatic blade modeler, a wind flow generator and the performance evaluation under operating conditions. This is a window based PC program written in visual C language and designed to cooperate with the commercial CAD and FEA software. The blade profile can be built automatically once all the design parameters are specified. Furthermore, intensive aerodynamic analyses of the blade design can be carried out with the aid of wind flow generator. This integrated computer program has been employed for the blade design of the laboratory scale 150KW wind turbine generator to verify its efficacy.
