The average age of aircraft in the U.S. Air Force is 22, making aging an increasing concern. The Air Force program responsible for maintaining the structural safety of its aircraft faces challenges, however, such as budgetary pressures, regulations, and communication issues. The authors sought insights on these issues by comparing similar programs in other services. Their observations suggest the value of clear policies, independent assessments, standard metrics, and open and clear communication.

Over the next 20 years, the further aging of already-old aircraft will introduce challenges and issues for aircraft operators. The technical challenges relate to structures, propulsion, and systems. The institutional challenges include limitations on independent verification of fleet status and future condition and on information needed for engineering analyses including risk assessment, and an overall scarcity of resources.

This study evaluates the health of the U.S.-Canadian defense industrial relationship, which is critically important as the U.S. Department of Defense expands the national technology and industrial base. The CSIS study team gathered and analyzed a wide range of quantitative data and conducted interviews with government and industry officials involved with bilateral cooperation on both sides of the border. In addition to looking at top-level history, legislation, policy, and trends, the study team undertook five sectoral case studies highlighting different aspects of the benefits from and challenges facing bilateral cooperation. The study finds that the benefits to both partners exceed what either could obtain solely by relying only on its own national resources. While the overall U.S.-Canadian defense industrial relationship remains sound, the study team identifies a range of recommendations to enhance its value to both partners.

Download Structural Health Monitoring (SHM) in Aerospace Structures Book in PDF, Epub and Kindle

Structural Health Monitoring (SHM) in Aerospace Structures provides readers with the spectacular progress that has taken place over the last twenty years with respect to the area of Structural Health Monitoring (SHM). The widespread adoption of SHM could both significantly improve safety and reduce maintenance and repair expenses that are estimated to be about a quarter of an aircraft fleet’s operating costs. The SHM field encompasses transdisciplinary areas, including smart materials, sensors and actuators, damage diagnosis and prognosis, signal and image processing algorithms, wireless intelligent sensing, data fusion, and energy harvesting. This book focuses on how SHM techniques are applied to aircraft structures with particular emphasis on composite materials, and is divided into four main parts. Part One provides an overview of SHM technologies for damage detection, diagnosis, and prognosis in aerospace structures. Part Two moves on to analyze smart materials for SHM in aerospace structures, such as piezoelectric materials, optical fibers, and flexoelectricity. In addition, this also includes two vibration-based energy harvesting techniques for powering wireless sensors based on piezoelectric electromechanical coupling and diamagnetic levitation. Part Three explores innovative SHM technologies for damage diagnosis in aerospace structures. Chapters within this section include sparse array imaging techniques and phase array techniques for damage detection. The final section of the volume details innovative SHM technologies for damage prognosis in aerospace structures. This book serves as a key reference for researchers working within this industry, academic, and government research agencies developing new systems for the SHM of aerospace structures and materials scientists. Provides key information on the potential of SHM in reducing maintenance and repair costs Analyzes current SHM technologies and sensing systems, highlighting the innovation in each area Encompasses chapters on smart materials such as electroactive polymers and optical fibers

Download Opportunities for Systems Engineering to Contribute to Durability and Damage Tolerance of Hybrid Structures for Airframes Book in PDF, Epub and Kindle

The structures making up airframes must be durable and damage tolerant, and the means of ensuring that they are have long been well defined for structures made of metal. But a host of new hybrid materials, some of which contain no metal, are now being used, and these can present new damage mechanisms that engineers must address. The Air Force has established a general approach to airframe durability and damage tolerance. The author examines that approach and considers ways it will need to adapt for the new materials. Given the variety of materials, processes, and end uses involved, the engineering effort will necessarily involve multiple specialties. In these circumstances, the tailoring process could benefit from the efforts of systems engineers. The report addresses both technical and programmatic concerns and identifies opportunities for materials and structural engineers to collaborate with systems engineers. Finally, it offers a framework for collaboration.
