Revised Structural Technology Evaluation Program (STEP) User's Manual for Structural Synthesis.

Abstract

This report presents the description of a structural synthesis program used within the Structural Technology Evaluation Program (STEP). This program is the revised version of APAS III (Automated Pre-Design of Aircraft Structure). The reversion includes implementation of a fatigue crack-growth analysis methodology which realistically accounts for the spectrum load interaction effects to crack growth. Additional work was to add to the program the capability of producing fighter aircraft load spectra. (author)
