What is Conceptual Design of Aircraft ?
While doing the Conceptual Design phase a designer makes a lots of conceptual models and compare them to select the best conceptual design. For this he compares the model on the basis of various objective like Cost of Aircraft, Weight Of Aircraft, Design Time Period for making that model, Performance Factor, Maintainability Factor, Producibility Factor, Beauty (or Aesthetics) Factor, etc.
How to Calculate Minimum design index?
Minimum design index calculator uses Minimum Design Index = ((Cost Index*Cost Priority (%))+(Weight Index*Weight Priority (%))+(Period Index*Period Priority (%)))/100 to calculate the Minimum Design Index, The Minimum design index formula is defined as sum of products of objective indices and their respective priorities percentage of Cost, Weight, and Design Time factors whole divided by hundred. Minimum Design Index is denoted by DI_{min} symbol.
How to calculate Minimum design index using this online calculator? To use this online calculator for Minimum design index, enter Cost Index (CI), Cost Priority (%) (P_{c}), Weight Index (WI), Weight Priority (%) (P_{w}), Period Index (TI) & Period Priority (%) (P_{t}) and hit the calculate button. Here is how the Minimum design index calculation can be explained with given input values -> 31.1 = ((55*10)+(50*15.1)+(95*19))/100.
