“…Both research groups concluded that flutter would be determined in the prototype development phase. 7 Zink et al go on to state that it is at this early design stage that the complex problem can be most effectively and economically addressed. Weisshaar puts it clearly as follows: consideration and prediction of aeroelastic effects are essential for the efficient design of high performance flight vehicles.…”

The paper defines an innovative, novel design methodology that results in a product that effectively satisfies the designer's needs and requirements. Use is made of the response surface methodology after consideration of other metamodeling techniques. Drawbacks of the response surface methodology are mitigated by incorporating sensitivity information in the response surface creation. The definition, application, and eventual implementation of this emerging design tool for new product design is described. The new methodology envisioned will make use of the bi-level integrated system synthesis decomposition for distributed computing. The overall goal is to accomplish cheaper, faster, better designs for structural systems and components. This research leads to the discussion of the use of design tools for structural optimization, including the dynamic aeroelastic constraints.

“…Multidisciplinary aircraft design and evaluation (MADE) is an integrated software facilitating the rapid developing of multidisciplinary applications for aerospace vehicles design [14]. DREAMS developed by Georgia Tech Aircraft System Design Lab has been applied successfully in the concept design and preliminary design stages of high-speed civil transport wing [15]. A distributed MDO platform which mainly resolves expensive data management and user collaborative problems was developed, and has been used for the missile design and optimization [16].…”

Ship design is a complex process, which contains many coupled disciplines and needs the collaboration among geographical distributed design resources. Multidisciplinary Design Optimization (MDO) provides a promising way to ship design compared to traditional spiral design approach. As the important enabling tool, MDO framework is vital to the successful implementation of MDO problems. In this paper, at the base of surveying the state of the art of some notable MDO frameworks, a Web services and Isight based distributed ship MDO framework is proposed, which provides an easy way to integrate distributed design, analysis, optimization services, namely various tools and programs, to jointly implement ship design. At the same time, according to the requirements of ship design, some new and extended function modules are added, which incorporates a number of existing technologies such as workflow, component technology.

“…PROBABILISTIC METHODS AT THE ENGINEERING LEVEL -Much work has been done recently using probabilistic methods at the individual aerospace concepts level [13,14,15,16]. Metamodels based on regression methods have been created relating vehicle design variables (geometry, engine specifications, drag polars, etc) to vehicle responses (takeoff gross weight, thrust-to-weight ratio, etc.).…”

Significant advances have been made recently in applying probabilistic methods to aerospace vehicle concepts.Given the explosive changes that are occurring in today's political, social, and technological climate, it makes practical sense to try and extrapolate these methods to the campaign analysis level. This would allow the assessment of rapidly changing threat environments as well as technological advancements, aiding today's decision makers. The following paper summarizes attempts to apply these methods directly to campaign analysis, and discusses the resulting issues that were identified as potential problem areas. A new approach is postulated which includes the application of probabilistic methods to a fully linked analysis environment.Applying and validating these new methods is an ongoing project.
