Description
The Aging Aircraft and Durability (AAD) Project is part of the NASA Aviation Safety
Program. The goal of the AAD Project is to perform foundational research in aging
science that will ultimately enable system-level integrated methods for the detection,
prediction and mitigation/management of aging-related hazards for future civilian and
military aircraft. The Project is organized relative to these three theme areas:
Detect locate and characterize fully damage or degradation of materials and
structures
Predict life and strength predictions accounting for accumulated damage
associated with long-term exposure to thermal/mechanical/environmental loads
Mitigate concepts to prevent, contain, or manage degradation associated with
aging
B-4
The focus of AAD is on aging and damage processes in new aircraft designs and 'young'
aircraft, rather than life extension of legacy vehicles. There is an emphasis on new and
emerging material systems/fabrication techniques and the potential hazards associated
with aging-related degradation. The scope and technical content for the AAD Project
was developed to accomplish two objectives: (1) deliver technology to address specific
end-user problems and (2) develop fundamental technology (not isolated to a single
application) to enable integrated tools.
The first objective was addressed by establishing a set of Challenge Problems (CP) to
define representative physical problems to be addressed by the project. Challenge
Problems have been defined for eight application problems:
CP-01: Damage Methodology for Metallic Airframe Structures
CP-02: Structural Integrity of Integral Metallic Structure
CP-03: Durability and Structural Integrity of Composite Skin-Stringer Fuselage
Structure
CP-04: Durable Bonded Joints
CP-05: Durability of Engine Fan Containment Structure
CP-06: Durability of Engine Superalloy Disks
CP-07: Durability of Engine Hot Section
CP-08: Wiring Degradation and Faults
To accomplish the second objective, fundamental technology development not isolated to
a single application, AAD has defined a four-level approach to technology development
and integration, and will conduct research across each of these levels to address evolving
safety challenges. At Level 1, foundational research will be conducted to further the
fundamental understanding of the underlying physics and develop an ability to model that
physics in: sensing and diagnostic technologies; physics-based modeling; continuumbased
models and computational methods; material science (metals, ceramics,
composites); and characterization/validation test techniques. At Level 2, the foundational
research produces technologies and analytical tools focused on discipline-based solutions
to leverage the development of NDE Systems; Structural Integrity tools; Lifing methods;
and Mitigation concepts. At Level 3, methods and technologies are developed to balance
solutions across disciplines. The Detect capability is enhanced by coupling NDE and
structural integrity analysis, the Predict capability is enhanced by applying NDE to
improve model input and provide improved remaining life and strength predictions, and
the Mitigate capability is enhanced by applying predictive models to develop advanced
mitigation concepts. At Level 4, results from Levels 1 through 3 activities are built upon
to integrate Detect, Predict, and Mitigate capabilities for system-level performance, and
system-level experiments are conducted for validation. A summary of the Projects
technical plan is available at: http://www.aeronautics.nasa.gov/programs_avsp.htm
NASA will focus its core competencies and resources on NASA-appropriate research
areas at all levels, and with partners, on the levels that are appropriate to each partner.
The AAD Project will work with partners from other government agencies, industry, and
universities to fills the gaps that NASA research cannot address. This solicitation is
intended to fill such gaps at Level 1 and Level 4. The proposed research efforts are an
B-5
integral component of the overall project content and have been defined to contribute to
specific Challenge Problem and Theme-based technology needs.
