Changes in USAF Structural Loads Requirements

Abstract

The new General Specification for Aircraft Structures, MIL-A-87221 (USAF), does not establish the traditional, fixed requirements, but instead it presents the current tailored approach to establishing structural loads requirements. In most cases the previous specifications set arbitrary load levels and conditions to be used in aircraft design. These requirements were based on historical experience, without consideration of future potnetial needs or capabilities brought about by technology advances. Instead, the new philosophy requires that loading conditions be established rationally for each weapon system based on anticipated usage. Also, compliance with each condition must be verified by analysis, model test, or full scale measurement.
