Within a conventional aircraft design process, the horizontal tail and vertical are generally sized via volume coefficient methods. In this manuscript, an improved method for conceptual based on multidisciplinary optimization (MDO) approach with stability control constraints has been developed. To develop method, first, requirements have derived from regulations fundamental functionalities of p...

In the architectural design, designers are focused on the early stages of the design process or conceptual design. The ultimate goal of this stage is to find a solution for an existing problem, investigate design space, or explore an idea. This stage conventionally begins with sketches and diagrams to explore ideas and solutions; the ambiguity and vagueness of conventional freehand sketching ca...

This paper gives an insight to some of the intrinsic issues related to the understanding and the computer support of conceptual design. On the one hand, the academic research and development have produced innumerable methods and techniques to support product conceptualization. Reasonable progress has been achieved in (a) the understanding of the fundamental reasoning mechanisms, (b) the develop...

This paper introduces new approaches to the conceptual design of electro-mechanical systems from qualitative specifications of behaviour and function. The power of these methods stems from the integration of techniques in qualitative physics, symbolic mathematics , computational geometry and constraint programming. This is illustrated with an effective kinematic synthesis method that integrates...

Due to the development of the internet and cable nets information services are going to be widely used. On the basis of projects for the development of information services like regional information services or shopping services we develop a method for the creation of information systems and services to be used through diierent nets. The approach is based on the codesign of data, dialogues and ...

A software tool for the prediction of the aero-thermodynamic environments of conceptual aerospace configurations is presented. The vehicle geometry is defined using unstructured, triangulated surface meshes. For subsonic Mach numbers a fast, unstructured, multi-pole panel code is coupled with a streamline tracing formulation to define the viscous surface solution. For supersonic and hypersonic ...

Conceptual design is a process of creating functions, forms and behaviors. Although cognitive processes are utilized in the development of new ideas, conventional methodologies do not take human cognition into account. However, it is conceivable that if one could determine how cognitive processes are stimulated, then more effective conceptual design methods could be developed. In this paper, we...

Systematic approaches for the invention of conceptual chemical process designs have been proposed and discussed for more than twenty-five years, and have now been developed to the point of industrial application. Process synthesis has also now become an integral part of many chemical engineering design curricula. CACHE has contributed to the promotion and advancement of conceptual design and pr...
