Abstract:

Three computer programs were written with the objective of predicting the structural weight of aircraft through analytical methods. The first program, the structural weight estimation program SWEEP is a completely integrated program including routines for airloads, loads spectra, skin temperatures, material properties, flutter stiffness requirements, fatigue life, structural sizing, and for weight estimation of each of the major aircraft structural components. The program produces first-order weight estimates and indicates trends when parameters are varied. This volume Volume 9 contains the instructions and input descriptions for use of the integrated SWEEP program.
