Intelligent composite structures with self-aware functions are preferable for future aircrafts. The real-time location of damaged areas composites is a key step. In this study, deep transfer learning was used to achieve the areas. sensor network obtained acoustic emission signals from different aluminum alloy plate. time-domain signal transformed into input image by continuous wavelet transform. convolutional neural network-based model automatically localized area extracting features image....
In actual flight conditions, the surface of thermal protection materials may experience stress, and impact strain on catalytic reaction mechanical–chemical coupling has not been fully explored. this study, a gas–solid interaction model was constructed using molecular dynamics density functional theory methods. The characteristics α-SiO2 (001) under up to 2% uniaxial biaxial tensile were investigated. Results indicate that both stretching along X axis Y axes inhibit recombination at higher...
Integrated thermal protection systems with both and load-bearing capabilities are regarded as one of the most promising concepts for future hypersonic vehicles. Yet improper design could cause structure to be overweight even fail prematurely during service. In this paper, thermal–mechanical analysis model integrated is first established, short mismatch effects typical corrugated web concept studied. Three improved structural proposed. Thermal insulation capability analyses strength,...
Charring ablators are widely used for the thermal protection structure (TPS) of return capsules. However, adopting only a single type ablator limits structural efficiency TPS due to and insulation requirement conflicts. Here, we report on different types hybrid TPSs improve heat-shielding performance. An ablative-thermal-structural analysis model was first established based finite element method, optimization analyses were performed determine sizes structures. Meanwhile, an evaluation...
We report on a quantitative quasi-distributed vibration sensing (DVS) system enabled by phase-sensitive optical frequency domain reflectometry (φ-OFDR), which allows for multiple events over consecutive spatial resolutions. To achieve effective crosstalk suppression and mitigation of the instability during phase extraction, fiber with embedded ultra-weak grating arrays has been adopted as fiber. It exhibits particularly customized low duty cycle, that is, high ratio between size gratings...
