What is Design Index Concept and How to derive Weight index?
At the start of Conceptual Design, the Designer defines Objective index which depends upon the parameters which influence the respective objective. Sum of all of the parameters contributing the objective factor on scale of 1-10 gives objective index. Now this objective index has its own priorities, in a conceptual design model the priorities are shown in percentage. Now how these factor influence the model is given by the product of the objective index and its priority (taken as a number (conversion from percentage)), it is the share of design index. And if the share of design index is subjected to the Cost, Weight and Design Time only, It is called Minimum Design Index. As they are common factors in all type of Aircrafts. The Weight Index can be Derived from the same as we have to modify the formula.
How to Calculate Weight Index given Minimum Design Index?
Weight Index given Minimum Design Index calculator uses Weight Index = ((Minimum Design Index*100)-(Cost Index*Cost Priority (%))-(Period Index*Period Priority (%)))/Weight Priority (%) to calculate the Weight Index, The Weight Index given Minimum Design Index formula elucidates the relationship between the weight index and the MDI in aircraft design and operation, it serves as a metric for evaluating the weight efficiency of aircraft configurations and operational strategies. Weight Index is denoted by WI symbol.
How to calculate Weight Index given Minimum Design Index using this online calculator? To use this online calculator for Weight Index given Minimum Design Index, enter Minimum Design Index (DImin), Cost Index (CI), Cost Priority (%) (Pc), Period Index (TI), Period Priority (%) (Pt) & Weight Priority (%) (Pw) and hit the calculate button. Here is how the Weight Index given Minimum Design Index calculation can be explained with given input values -> 903.2417 = ((160*100)-(1327.913*10.11)-(95*19))/15.1.
