Aircraft Structural Life Extension

Analyze Today For A Safer Tomorrow.

The scope of this effort may cover a variety of structures (from a micro-level up to aircraft, ships, tanks, ground support equipment, bridges and other varieties of aging structures).

The contract scope of work includes engineering tasks and research activities for aging structures. Mission changes and structural modifications have changed the structural behavior in ways not envisioned by the original designers. Because of these, the engineering and analysis activities surrounding structural sustainment have moved beyond the routine and are now focused more toward research and development. This move from a “find and fix” mentality to one of “anticipate and manage” requires predictive tools and expertise in the analysis that goes far beyond routine engineering support. Structural sustainment demands an understanding of the physical principles underlying damage progression, and the development of new, cutting-edge tools and techniques to maintain both certification and economical operation.
