Large Aircraft Rapidly Deploys Customizable Mission Recording System. 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). SHM solutions require. Chapters within this section include sparse array imaging techniques and phase array techniques for damage detection. SHM is aimed to be one of the key technologies to control the structural integrity in future aircrafts providing both maintenance and weight saving benefits. Built through decades of experience and heavy R&D investment, the Acra KAM-500 is an international leader in airborne data acquisition for flight testing. SHM systems aim to monitor aircraft components in near real-time and detect structural defects when they happen. Structural health monitoring (SHM) is receiving considerable attention because of the growing demand for innovative approaches to preventing damage in larger infrastructures. By continuing you agree to the use of cookies. 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.

To improve the performance of piezoelectric devices, selection of piezoelectric materials with optimized properties is critical. Curtiss-Wright has partnered with Critical Materials to offer complete SHM solutions that combine Acra KAM-500 instrumentation units with Critical Materials tailored detection algorithms. 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. Curtiss-Wright offers highly compact and lightweight quick access recorders for use in several aerospace applications. Our support team can help answer your questions - contact us today. Watch our video to learn more. Designing a Thermally Optimal Data Acquisition Unit. Critical flaws may be induced in the structure requiring repair before the next scheduled inspection. Our SHM solutions do not rely on bulky NDI equipment and techniques, but rather use a minimized number of low-cost sensors to guarantee a specified POD (probability of detection), e.g. - Gold for VME-1910 6U VME SBC There is a good awareness of the benefits of SHM within the aerospace community for many years, however it is only now that widespread adoption has taken off, driven in a large part by the introduction of composite structural components. Part Three explores innovative SHM technologies for damage diagnosis in aerospace structures. A manufacturer of a large military aircraft required a mission recording system to... New Commercial Airliner Rapidly Deploys Customizable Mission Recording System. Aircraft Monitoring and Sustainment Brochure, Case Study: EH101 Structural Health Monitoring, White Paper: Continued Airworthiness - Assuring a Lifetime of Safe Flight. 12 accelerometers optimally distributed on a wing-surface to guarantee detection of defects with surface area >1cm2. A SHM system feeds into a Condition Based Maintenance (CBM) regime, where aircraft maintainers can  efficiently direct their resources towards the aircraft that actually require repair, the result is less overall maintenance effort and increased aircraft availability. Curtiss-Wright manufactures compact and lightweight CPRs that feature a hard mountable form factor, optional data acquisition capabilities and software configurable role select for further customizability. Watch the Total LifeCycle Services video to learn about bridging the gap between cost-effective COTS components and today's complex defense programs. Air data computers are used by aircraft to acquire and process data from pitot and static pressure sensors, data buses and analog inputs to obtain key air data parameters. Curtiss-Wright provide Acra KAM-500 to SHM integrators who require flexible, high-fidelity data management units. These recorders are highly rugged and ideal for storing data from data sources such as data acquisition systems or on-board avionics buses. The uses of Structural Health Monitoring (SHM) technologies for future aircraft will not only enable new possibilities for maintenance concepts, but will have a big in-fluence on design concepts and assembling technologies. - Gold for VPX3-673 Card This paper discusses some of the challenges imposed on FTI, both at the hardware... Meeting Recommended, Likely, and Newly Introduced Recorder Regulations for Light Aircraft and Rotorcraft. Involving telecommunication service providers (TSPs): TSPs are gradually getting involved in the … Careers | 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. You currently don’t have access to this book, however you Piezoelectric-based sensors/actuators play an important role in structural health monitoring (SHM) of modern aerospace structures. In addition, this also includes two vibration-based energy harvesting techniques for powering wireless sensors based on piezoelectric electromechanical coupling and diamagnetic levitation. 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. Structural health monitoring (SHM) has become an important process in maintaining the proper state of composite structures. Login | Rather than just reporting loading cycles on a structural components, a SHM system will report actual changes in structural components. 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. Part Two moves on to analyze smart materials for SHM in aerospace structures, such as piezoelectric materials, optical fibers, and flexoelectricity. ©2020 Curtiss-Wright. The final section of the volume details innovative SHM technologies for damage prognosis in aerospace structures. SHM is becoming important for new composite airframes where traditional metal fatigue models are not useful and where damage is often not apparent at the surface. Aircraft maintainers and operators who use Structural Health Monitoring (SHM)  systems are able to determine if structural damage has occurred, when the damage event occurred and precisely where the damage is located.
