Design Case Study

In the field of the widespread research activity focusing on ultra light aircraft, two different needs were merged into one single design activity: the educational necessity of getting students involved into a real design effort. Our intention was to apply the conceptual design methodologies developed by our research group, which is named ASSET (Aero Space Systems Engineering Team), to a real case study. The design case study was chosen after a thorough examination of existing vehicles. Starting from a reference aircraft, the concept of the new aircraft was then conceived and is now under completely defined. The conceptual design of the new ultra light aircraft is already finished, whereas its detailed design has just begun and is proceeding through the utilization of both virtual (3D‐CAD) and physical models.

Coupling Sequence

Conceptual design is the stage where the upstream objectives and downstream constraints meet, so both the ideality and practicality are important in conceptual design. Modularity supports designing complex system while the design can take advantages from the downstream resources. According to Axiomatic Design Theory (ADT), the design with the least complexity is the ideal design, and managing functional coupling sequence can lead to the minimal complexity of design concepts. In this paper, Design Coupling Sequence (DCS) was introduced to bridge the ADT and the modular design. The ‘precedence’ and ‘functional sets’ were defined in DCS to manage the coupled design concepts in order to support the modularity of the design concepts. The ‘precedence’ identified by the level of functional coupling helps realize the sequencing order. The two ‘functional sets’ were defined as the independent U-set: the collection of functionally dependent concepts, and the coupled C-set: the collection of the strongly coupled concepts. The faucet design case study shows how the DCS method and its strategy to decrease relative complexity and increase modularity, and the results between design by extra coupling elimination and design by the existing modules are compared. The DCS method bridges the design theory to design practice.

Structured Model

<p>Requirement study and analysis forms a key component in conceptual design of new products and systems. For complex systems like defence equipment, concept design is very important and should primarily satisfy all user requirements. Brings out a new generative model for concept design of defence systems using principles of systems engineering. A structured model and methodology is presented starting from capturing the user requirements, developing multiple solutions, short listing the candidate solutions and finally selecting one or two feasible designs. The model and process is illustrated with the help of a case study on the development of a torpedo defence system for naval ships.</p><p><strong>Defence Science Journal, Vol. 66, No. 1, January 2016, pp. 81-87, DOI: http://dx.doi.org/10.14429/dsj.66.9105</strong></p>
