Abstract The expectations of computer tools to support the conceptual design phase are not yet met. An experimental approach to discover the use of information in conceptual design will give a realistic insight of the information requirements. This can be used to specify future computer support systems. A method to observe the use of information in a conceptual design process has recently been developed. The method has been tested and fine-tuned through the observation of 10 design sessions. Valuable empirical data resides from this experiment. Data has been analyzed in several perspectives. This paper presents the results of the activity/information analysis of the experiment in relation with the quality of the design concept. For the latter a rating system has been defined to quantify this. We have found a significant positive correlation of the amount of information that is communicated and the quality of the design. Furthermore a discussion is given on the relation between information and the activities of the designer. Analysis activities are more communication intensive compared to synthesis and evaluation tasks.

Increase Efficiency

Analysis of competing options for the implementation of the system is a key task at the stage of conceptual design of aviation air conditioning systems as these systems have a great impact on the fuel efficiency of the entire aircraft. The decision about choice of competing options regarding not only the appearance of the system, but also a lot of different parameters including technical, technological and so on. In case of conceptual design missing parameters for a complex criterion can be replaced by an alternative risk level estimate. This article shows an example how to compare competing variants of the air management system at the stage of conceptual design and provides a methodology for selecting the key parameters of the comparison criterion. As a result, it is shown that vapor cycle cooling is more promising due to the wide possibilities of reducing the mass of components and increasing the overall cooling efficiency. For the air cycle, most of the possible solutions to increase efficiency have already been implemented now.
