DBF Q&A #6

Q: I was looking over the writing component of the DBF contest and under 
the Conceptual Design section, I noticed you wanted the Design Parameters 
investigated and Figures of merit used to screen competing concepts.   I 
was wondering if you could clarify what you mean by "Design Parameters" and 
"Figures of merit" and perhaps give a few examples of each.

A: Design parameters are any characteristics used to discriminate between 
different design options.  They might include, but not be limited to, wing 
span, area, AR, pusher/tractor, tricycle/tail dragger, number of engine, 
conventional/canard tails, one wing/two wings,.....

The Figures of Merit are the computed parameters used to determine the 
advantage or disadvantage of each of the design parameters.  They could 
include, but not be limited to, cost, weight, take-off speed, cruise speed, 
various handling parameters such as turn radius or rate, ease of 
construction, power required, maximum flight endurance,....
