“…These high-value assets include but not limited to, civil and military aircraft [2], wind turbines which make a significant contribution towards renewable energy generation [3], and metal or plastic-lined composite pressure vessels that are used as fuel tanks for space vehicles and other applications [4,5]. However, composite structures do have weaknesses which is highly susceptible to damage from accidental impacts [1,[6][7][8][9][10]. Multiple studies have been conducted and found that even relatively low-energy impacts that leave little to no visual evidence of damage can cause substantial reductions of up to 60% in compressive strength [7,8], which presents an unacceptable risk of failure for such high-value or safety critical structures.…”

Abstract. Fibre reinforced composites have been discovered to have superior material properties compared to traditional materials. However, composite structures do have weaknesses which is highly susceptible to damage from accidental impacts. Passive approaches have gained popularity in recent years as these can be implemented using less structurally and electrically obtrusive sensor installations. The fundamental hypothesis is that every distinct impact event has a unique modal signature that can be exploited to distinguish between damaging and nondamaging impacts, and to characterize the severity of damage. Preliminary research showed that the possibility to determine the progressive failure mechanism in composite specimens subjected to three-point bending. Each failure mechanisms have its corresponding frequency bandwidth, and it can be seen by plotting the spectrogram of time-frequency analysis. However, the limitation of time-frequency analysis for identifying failure modes arises from the fact that there can be a confluence of modes having more-or-less the same group velocity hence, having the same arrival time in a time-frequency plot for a given frequency. This overlap makes it problematic to identify modes unambiguously from a time-frequency analysis. The modes can be more clearly separated on the basis of dispersion curves obtained in the frequency-wavenumber space. This information paves way to the idea of developing a modal sensor that is capable of providing experimentally determined dispersion curves that can be expected to lead to a quantum advance in capability for modal identification, and hence for determining a far more accurate modal signature for various acoustic emission events.

“…The IVHM software will never directly command any vehicle subsystems and under no circumstances would its recommendations be acted upon automatically by the vehicle. The VMS then telemeters this information to the ground, where ground software processes and displays the information [15][16][17].…”

The references at home and abroad are summarized in this paper. This paper introduces the basic concept and the application significance of aerospace plane, the main differences between the aerospace plane and general aircraft, integrated health management system and its compositions of aerospace plane , the development status of health management for aerospace plane in domestic and foreign countries. Especially it recommends special technical experiments in America, Japan and Italy, and analyzes the health management approaches of them. Finally, it also describes the main fault diagnosis methods. Integrated health management of aerospace plane generally involves a series of activities, including signal processing, monitoring, health assessment, failure prediction, decision support, humancomputer interaction, restoring, and so on. In addition, this paper predicts development direction of health management for the aerospace plane.

“…Although sensor suites tend to be specific to the application domain, a few developmental sensor technologies are taking central stage in the IVHM domain. These include micro and fibre optic technologies that reduce sensor size, weight, and support requirements [19,42] together with increasingly advanced smart sensors that have Fig. 2 Architecture of an IVHM system opened up the possibility for widespread introduction of embedded sensor systems [13].…”

Integrated Vehicle Health Management (IVHM) is the collection of data relevant to the present and future performance of a vehicle system and its transformation into information that can be used to support operational decisions. This design and operation concept embraces an integration of sensors, communication technologies and artificial intelligence in order to provide vehicle-wide abilities to diagnose problems and recommend solutions. This paper aims to report the state-of-the-art of IVHM research by presenting a systematic review of the literature. Literature from different sources is collated and analysed, and the major emerging themes are presented. On this basis, the paper describes the IVHM concept and its evolution, discusses configurations and existing applications along with potential benefits and barriers to adoption, summarises design guidelines and available methods, and identifies future research challenges.
