The Study of Reliability in MDO of Aircraft
Applied Mechanics and Materials, 2012MDO and reliability design are independently processed in the traditional aircraft design. The designs process is thus consuming compute intensive, so that integrated design of MDO and reliability is required. To achieve the integration, there are two problems needed to be solved.

Aircraft loads methodology for MDO
19th AIAA Applied Aerodynamics Conference, 2001A methodology is presented for developing a complete set of aircraft loads to be used in the structural optimization of an aircraft wing during preliminary design. Using the software program ASTROS as the platform, a typical mid-size 100+ seat passenger aircraft was selected as the subject of the study.

Recent Advances in Relativistic MDOs
2019 International Vacuum Electronics Conference (IVEC), 2019The relativistic magnetron is the most compact and efficient high-power microwave (HPM) source. It has been researched since Bekefi's pioneering work in 1975 at MIT. The performance of the relativistic magnetron did not dramatically improve until the $\pmb{2000}\mathbf{s}$ when new cathode concepts were introduced independently by researchers at the ...

Controllable Axial Overmoding in an MDO
IEEE Transactions on Plasma Science, 2012During a computational investigation of a magnetron utilizing a diffraction output, it was discovered that axial overmoding allowed more than one π mode to exist. Further investigation led to the identification of at least four distinct π modes, each with its own frequency and associated 2π/3 and 4π/3 modes, each accessible by appropriate choices of ...

On the Application of Differential Geometry to MDO
12th AIAA Aviation Technology, Integration, and Operations (ATIO) Conference and 14th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2012Multidisciplinary Design Optimization (MDO) is a methodology for optimizing large coupled systems. Over the years, a number of different MDO decomposition strategies, known as architectures, have been developed, and various pieces of analytical work have been done on MDO and its architectures.

Synthesizing an MDO Architecture in CAD
42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004This paper presents an approach to multidisciplinary design optimization (MDO) that uses computer aided design (CAD) as both a way to integrate computational tools and as a novel way of formulating the optimization problem. CAD typically forms the final step in a design process, as a repository of the final design and a precursor to manufacturing . The

6th Symposium on Multidisciplinary Analysis and Optimization, 1996
The purpose of this paper is to discuss the use of Computer-Aided Design (CAD) geometry in a Multi-Disciplinary Design Optimization (MDO) environment. Two techniques are presented to facilitate the use of CAD geometry by different disciplines, such as Computational Fluid Dynamics (CFD) and Computational Structural Mechanics (CSM).

MDO — A Mathematical View Point
1998A quantitative analysis of coupling between systems of equations is introduced. This analysis is then applied to problems in multidisciplinary analysis, sensitivity, and optimization. For the sensitivity and optimization problems both multidisciplinary and single discipline feasibility schemes are considered.
