TL;DR: The need for accuracy in estimating the component weights of project designs cannot be over-emphasized, forming, as they do, an important part of the stressing and performance calculations.
Abstract: THE need for accuracy in estimating the component weights of project designs cannot be over‐emphasized, forming, as they do, an important part of the stressing and performance calculations. Of the items controlled by the airframe manufacturer, the wing is not only the heaviest (often representing as much as 50 per cent of the structural weight), but is also the most difficult to predict. In order to arrive at a suitable figure, numerous formulae have been used in the past, these falling into two broad categories:
