In this context, the authors are part of a team that is studying various tether applications and building a prototype of an electrodynamic tether system. The goal of this paper is to characterize tether materials in order to find valid solutions for future space tether missions. Mission requirements (e.g., the survivability to hypervelocity impacts and the capability to damp oscillations in electrodynamic tethers) influence the choice of tether parameters such as cross section geometry (round wires or tapes), materials, length, and cross section sizes. The determination of the elastic characteristics and damping coefficients is carried out through a campaign of experiments conducted with both direct stress/strain measurements and the laboratory facility SPAcecRraft Testbed for Autonomous proximity operatioNs experimentS (SPARTANS) on a low friction table at the University of Padova. In the latter case, the stiffness and damping of a flexible line were verified by applying different tensile load profiles and then measuring the tether-line dynamic response in terms of tension spike amplitude, oscillation decay, and estimation of the damping coefficient.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123452759","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 APART-GAS trials combined the training of two NATO research task groups (RTG) operating within the SET Panel: SET-242 on passive radiolocation on mobile platforms (Passive Coherent Locators on Mobile Platforms) and SET-258 on multiband active and passive radars used in various military scenarios (DMPAR - Deployable Multiband Passive Active Radar Deployment and Assessment in Military Scenarios). The specificity of passive sensors, as well as the wide range of their applications resulted in numerous complications at the stage of developing and executing test scenarios conducted with the use of different aircraft types, including vertical launch rockets, water vessels and land vehicles. The article discusses successively the activities supporting the Warsaw University of Technology implemented by the Air Force Institute of Technology (AFIT). in the field of installing the sensors on individual platform, aircraft flight planning and their coordination in the course of the trials.

During their service life, these materials can suffer damage, sometimes difficult to detect, which may compromise their mechanical performances. The variation of the electrical properties of CFRPs is one of the strategies that can be used to monitor such damage. However, multiple variables contribute to this variation. This paper presents a preliminary analysis of the electrical impedance dependence on temperature and on damages outbreaks. The measurements are performed in controlled environment on a wide range of temperature and frequency. In some cases, the measured data show an impedance change due to the damage presence, which is of similar entity with respect to the variations caused by temperature. This may lead to misleading interpretations of impedance measurements in the absence of additional information. Hence the need of a proper temperature monitoring to possibly use electrical impedance spectroscopy analysis is required to unequivocally determine the health status of CFRPs.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122877146","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 development of inflatable robots, combined with the improvement of deployment mechanisms, allows to build novel lightweight and deployable robotic manipulators. In several space applications, the use of soft robots could minimize bulk and mass, reducing space mission costs. The main challenges in soft robotics are the control of the system and the exertion of high forces. In this manuscript, the concept of an inflatable manipulator with two inflatable links and three degrees of freedom is proposed. After a review about the possible materials to be used for the inflatable parts, the robot mechanical structure, the deploying strategy and the pneumatic line are presented. Then, an elastostatic approach is proposed to model the robot with the aim of developing its control. The last section shows preliminary experimental tests performed on the link prototype with the purpose to evaluate a static characterization in relation to the supplied pressure. Results suggest the validity of the adopted approach to model the system and clarify the pressure influence about the system performances. The study puts the basis for the development of the first prototype of the robotic system.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125529469","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}

If defects are fastly detected and, above all, segmented, further economical benefits may emerge since repairing strategies can be set up. Given this scenario, this paper presents an automatic methodology to process data from lock-in thermography inspections of composite laminates. Thermal analysis works on area scans of the target surfaces and, consequently, leads to complete information of the whole structure in a relatively short time. A deep learning network has been trained to analyze amplitude and phase maps to detect and segment defective inclusions. The reliability of this analysis is typically undermined by actual experimental issues, due to the homogeneity of the input excitation. For this reason, this study proposes a preliminary processing to manage the inhomogeneity of the input excitation, which typically adds a non-negligible bias to the amplitude and phase maps. The improved reliability has been proven through experiments performed on actual samples, coming from aerospace production lines. The outcomes of these experiments have proven a final per-pixel accuracy of 84.38% in the segmentation of buried defects.","PeriodicalId":236783,"journal":{"name":"2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125540227","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}
