Methods for Evaluating Weight Perfection Index for Aircraft

Such notions as Weight Perfection Index (WPI) and Weight Perfection Level (WPL) of a product are introduced and discussed. The latter is defined as a relative characteristic based on the comparison of a reduced WPI value for the estimated product with the reference value of WPI. A description of a procedure for reduced WPI estimation is presented along with a discussion of some features of a method for weight prediction. Discussed are examples of calculating the WPLs for undercarriage structure and passenger airplane.
