Risk Quantified Structural Design and Evaluation

Abstract

The objective of this program was to investigate the risk-quantified design methods for the design and certification of the structure for future military aircraft. The current Department of Defense (DoD) process for developing and supporting aircraft structures relies heavily on testing, including full-scale testing, to ensure structural integrity and reliability. This process adds cost and time to any new development program or service life extension effort. In the future DoD vision of lean, agile acquisition programs, a new paradigm is needed for making decisions about the airworthiness of an aircraft. Other industries, such as nuclear power and offshore oil, have developed a risk quantification process for deciding if a given structure should be placed in service. A similar risk quantification process could be applied in the airworthiness decision process for small aircraft fleets and hypersonic aircraft after adapting it to the DoD procurement process, the aircraft design process, and the safety issues particular to aircraft.
