Therefore, it becomes more and more important to study the overall design and construction of large luxury cruise ships. However, most of the existing papers on large luxury cruise ships are researched from a single perspective, and there is a lack of research to quantitatively analyze the design and construction problems of large cruise ships from an overall perspective. The paper proposes a method based on analytic hierarchy process (AHP) to evaluate the technical problems of design and construction in large luxury cruise ships.","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121779966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the evaporated-diffuse combustion process of aluminum particles in solid rocket motor chamber. We developed a quasi-steady two-dimensional evaporated-diffuse combustion model for a single aluminum particle. The evaporation rates of an aluminum droplet with spherical flame were calculated under different pressure. In addition, the effects of pressure and gas velocity on the combustion of gas and the micrometer-sized aluminum particle were investigated. The results show that the flame temperature increases with the rise of pressure. When the chamber pressure increases from 5MPa to 20MPa, the difference of maximum temperature in the flame zone reaches 610K; under the same chamber pressure (5 MPa), the deflection of the flame toward the flow direction is more significant at a higher gas flow rate. This indicates that the diffusion effect of combustion is more remarkable under high gas flow rate.","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130467428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the shortcomings of traditional fault diagnosis in feature extraction, the intelligent method based on deep learning combines feature extraction and classification to automatically isolate faults. In this paper, a method based on multi-channel one-dimensional convolutional neural network(1D-CNN) for fault diagnosis of hydraulic loading system is proposed. First, the four sequential sensor signals are preprocessed to form the input of the multi-channel 1D-CNN. Then, Multi-channel CNN extracts complex features from sensor signals and fuses features deeply. Finally, fully connected layer uses extracted features for fault classification. This paper uses indicators such as precision rate, recall rate and confusion matrix to analyze the effect of fault diagnosis. Compared with the multi-layer perceptron-based fault diagnosis method, the multi-channel 1D-CNN has higher accuracy and solves the problem of misjudging the health state as a fault. Experiments show that the method based on multi-channel 1D-CNN can effectively and accurately identify faults of the hydraulic loading system of altitude simulation test platform (HLS-ASTF).","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the sake of consistency, these two balloons are made of a high-density polyethylene (HDPE) plastic sheet with a thickness of 0.025 mm and are of similar volumes. In this study, the performance of these balloons is mainly assessed by the difference between the internal air temperature of a balloon and the ambient air temperature at a given solar radiation flux range. Three thermocouples are placed at an interval of approximately 0.5 m to measure the internal temperatures of the balloon. In conjunction with these measurements, a thermal camera is used to approximate the distributions of the temperature on the balloon surfaces. The results showed that the effects of solar radiation flux and altitude on the balloon lift force are similar for all envelope shapes and could be approximated with linear functions. Nevertheless, the spherical balloon is expected to be able to carry more payloads than the tetrahedral balloon as it weights less than the tetrahedral balloon of the same volume.","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134255448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reveal the underlying characteristics of internal combustion flows of pasty propellant rocket motor, a three-dimensional CFD simulation is established, considering the grain pyrolysis process, gas-solid coupled heat transfer as well as complex chemical kinetics and verified by comparing with experiment data. The results show that the flow in the combustion chamber of PPRMs presents strong three-dimensional characteristics, and the combustion process takes place in the extremely thin layer adjacent to the surface of propellant grain. Furthermore, with the increase of flow rate by 3 times, the thrust of the combustion chamber increases by 3.32 times, indicating the effectiveness of variable thrust adjustment of pasty rocket engine. The simulation accurately captures the combustion and flow characteristics, which provides guidance for the subsequent design optimization of the pasty propellant rocket motor.","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131912094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condensed phase products (CPPs) can effectively damp the acoustic waves of the instability, while the aluminum distributed combustion could drive the acoustic waves. Therefore, the study of the particle size distribution of aluminum combustion is essential for understanding the gain and damping factors of combustion instability. In this study, a dynamic combustion diagnosis system for measuring the particle size distribution of aluminum combustion is established, and the characteristics of particle size distribution under different oscillation were studied by the digital in-line holography (DIH). The results show that: influenced by the acoustic oscillation, the agglomeration process of aluminum particles on the burning surface will be different. Compared with the non-oscillation, the acoustic oscillation can affect the agglomeration of aluminum particles on and near the burning surface, and the mean diameter of D10, D32, D43, the agglomeration particle size (Dagg) and agglomeration fraction (fagg) all increase under acoustic oscillation.","PeriodicalId":198002,"journal":{"name":"2022 13th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115557273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
