Weight prediction for wings of box construction

The need for thin wings of high torsional stiffness leads to the use of box construction, in which both bending strength and torsional stiffness are provided by a single structural box. This report gives a method by which the wing weight for four types of box construction can be predicted from data available in the project stage of a new design....

Prediction of fuselage and hull structure weight

This report presents a method for predicting fuselage structure weight from data available in the project stage of a new design. The weights of the main structural components are calculated separately, account being taken of the peculiarities of each particular aircraft. The graphs and formulae are developed from analysis of about fifty British...

Prediction of undercarriage weights

This report presents a simple but accurate method of predicting undercarriage weight from data which would be available in the early project stage of a new design. The method was evolved by analysis of the weights of main components of undercarriages for over fifty aircraft types and tracing the features which influence undercarriage weight.
