What is Design Index Concept and Period of Design 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 Period of Design Index can be Derived from the same as we have to modify the formula.
How to Calculate Period of Design Index given Minimum Design Index?
Period of Design Index given Minimum Design Index calculator uses Period Index = ((Minimum Design Index*100)-(Weight Index*Weight Priority (%))-(Cost Index*Cost Priority (%)))/Period Priority (%) to calculate the Period Index, The Period of Design Index given Minimum Design Index formula provides insight into how the period of design index is determined based on the minimum design index, offering valuable information for aircraft manufacturers, operators, and regulatory bodies, it helps in assessing the longevity and adaptability of aircraft designs, guiding decisions related to fleet planning, technology integration, and regulatory compliance over the design lifecycle. Period Index is denoted by TI symbol.
How to calculate Period of Design Index given Minimum Design Index using this online calculator? To use this online calculator for Period of Design Index given Minimum Design Index, enter Minimum Design Index (DImin), Weight Index (WI), Weight Priority (%) (Pw), Cost Index (CI), Cost Priority (%) (Pc) & Period Priority (%) (Pt) and hit the calculate button. Here is how the Period of Design Index given Minimum Design Index calculation can be explained with given input values -> 772.3238 = ((160*100)-(50.98*15.1)-(1327.913*10.11))/19.
