A Structural Weight Estimation Program (SWEEP) for Aircraft. Volume III - Airloads Estimation Module. Appendix A: Module Flow Charts and FORTRAN Lists. Appendix B: Sample Output

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 3) contains the methodology, program description, and user's information for the airload module of SWEEP.
