TL;DR: NuMAD as mentioned in this paper is a software tool for reducing model development time and increasing the usability of advanced finite element analysis capabilities for wind turbine blades, which can reduce the complexity of wind turbine analysis.
Abstract: Given the complex geometry of most wind turbine blades, structural modeling using the finite element method is generally performed using a unique model for each particular blade analysis. Development time (often considerable) spent creating a model for one blade may not aid in the development of a model for a different blade. In an effort to reduce model development time and increase the usability of advanced finite element analysis capabilities, a new software tool, NuMAD, is being developed.

TL;DR: In this article, a design method is presented that has been implemented in a software program to investigate the merits of conventional and unconventional transport airplanes, including a parametric fuselage primitive and a lifting-surface primitive.
Abstract: A design method is presented that has been implemented in a software program to investigate the merits of conventional and unconventional transport airplanes. Design and analysis methods are implemented in a design tool capable of creating a conceptual design based on a set of toplevel requirements. In contrast to established design methods, emphasis is placed on designing unconventional as well as conventional airplane configurations. A parametric fuselage primitive and a parametric lifting-surface primitive have been defined. By combining various instances of these primitives, airplane geometries ranging from blended-wing-body configurations to threesurface configurations can quickly be generated. Analysis methods have been developed/refined such as to enable the (physics-based) disciplinary analysis of conventional and unconventional airplane concepts. Design rules have been implemented to automatically size the main airplane components. This paper describes the workings of the software tool, presents relevant validation studies and showcases a comparison study between five different airplane configurations.

TL;DR: The Prometheus Design Tool has recently been extended with two significant new features: support for Agent UML interaction protocols, and code generation.
Abstract: Prometheus is an agent-oriented software engineering methodology. The Prometheus Design Tool (PDT) is a software tool that supports a designer who is using the Prometheus methodology. PDT has recently been extended with two significant new features: support for Agent UML interaction protocols, and code generation.

TL;DR: NeoCASS as discussed by the authors is a design framework based on geometry construction, aerodynamic and structural analysis codes that combine depictive, computational, analytical and semi-empirical methods, validated in an aircraft design environment.
Abstract: This paper presents a design framework called NeoCASS (Next generation Conceptual Aero-Structural Sizing Suite), developed at the Department of Aerospace Engineering of Politecnico di Milano in the frame of SimSAC (Simulating Aircraft Stability And Control Characteristics for Use in Conceptual Design) project, funded by EU in the context of 6th Framework Program. It enables the creation of efficient low-order, medium fidelity models particularly suitable for structural sizing, aeroelastic analysis and optimization at the conceptual design level. The whole methodology is based on the integration of geometry construction, aerodynamic and structural analysis codes that combine depictive, computational, analytical, and semi-empirical methods, validated in an aircraft design environment. The work here presented aims at including the airframe and its effect from the very beginning of the conceptual design. This aspect is usually not considered in this early phase. In most cases, very simplified formulas and datasheets are adopted, which implies a low level of detail and a poor accuracy. Through NeoCASS, a preliminar distribution of stiffness and inertias can be determined, given the initial layout. The adoption of empirical formulas is reduced to the minimum in favor of simple numerical methods. This allows to consider the aeroelastic behavior and performances, as well, improving the accuracy of the design tools during the iterative steps and lowering the development costs and reducing the time to market. The result achieved is a design tool based on computational methods for the aero-structural analysis and Multi-Disciplinary Optimization (MDO) of aircraft layouts at the conceptual design stage. A complete case study regarding the TransoniCRuiser aircraft, including validation of the results obtained using industrial standard tools like MSC/NASTRAN and a CFD (Computational Fluid Dynamics) code, is reported. As it will be shown, it is possible to improve the degree of fidelity of the conceptual design process by including tailored numerical tools, overcoming the lacks of statistical methods. The result is a method minimally dependent on datasheets, featuring a good compromise between accuracy and costs.

TL;DR: OpenProp as discussed by the authors is an open-sourced computational tool for the design and analysis of optimized propellers and turbines, based on well-proven vortex lattice lifting line methods utilized by the US Navy as well as commercial designers.
Abstract: An open-sourced computational tool for the design and analysis of optimized propellers and turbines is presented. The design tool, called OpenProp, is based on well-proven vortex lattice lifting line methods utilized by the US Navy as well as commercial designers. This paper presents the methodology and numerical implementation of OpenProp, with multiple examples of designs, including actual parts fabricated from the code using 3D printing technology.
