The present procedure is based on the concept of randomness that has the undoubted vantage of the easiness, moreover, it is traditionally used so it is well known by scientists, technicians and experts in the field, but it a priori renounces to the knowledge of the causes that lead to failure. The paper presents a new approach to face the problematic showing that it is possible to follow new and more accurate routes and presents a typical application.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131360153","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 design wants to develop a passive vibration insulator for the Contamination Assessment Microbalance instrument, a quartz crystal microbalance for monitoring and measuring contamination in space environment. The ability of SMAs to act as efficient vibration insulators comes from their pseudo-elastic capabilities as the hysteretic force versus displacement behavior allows for energy dissipation. A 3D model of the instrument was developed to perform modal and dynamic random analyses aimed to identify the insulator mechanical characteristics and verify the instrument mechanical resistance. Moreover, a setup was designed to measure superelastic damping capacity of a commercial pseudoelastic shape memory alloy wire in dynamic tensile mode. The wire' specific damping capacity was then tested in different conditions, i.e. changing the excitation frequency and the amplitude of the deformation within a range of interest. The experimental activity allowed validation of the selected SMA wire for the intended application.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129011276","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 antenna under test considered in this work is a not-rotating array used for SSR (Secondary Surveillance Radar) made by elementary radiators disposed along the 360° in the azimuthal plane producing fan-fixed beam along elevation plane. The electronic scanning is achieved by activating a proper subset of elementary radiators along the ground plane generating antenna patterns related to their individual phase centers generally not coincident with the near-field scanning coordinate system. The mechanical position errors of the antenna under test are increased due to the large dimensions and the payload. The alignment procedure presented here, allows a near-field cylindrical scanning close to the antenna phase center reducing the distortions that can affect the measurements. The improvement is seen in terms of accuracy of the transformed far-field antenna pattern.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134416315","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}

Deorbit measures are required to mitigate the increase of debris population, and consequent collision risk, in space. The system proposed hereby is made of two bare electrodynamic tethers (BET), deployed with respective tip-masses, along opposite directions from Sylda, after its release in GTO at apogee. This paper investigates the design, optimization and simulation of a vision system to detect the position over time of the tip-masses during deployment. A representative deployment profile is used to select the vision system and optimize its key features, such as the focal length and the number of cameras. This design will also account for minimum cost and small size, that are crucial drivers for deorbit applications.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116956837","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}

Although it did not complete a safe landing on Mars, it transmitted data throughout its descent to the surface, until the loss of signal at 1 minute before the expected touch-down on Mars' surface. The main objective of the Atmospheric Mars Entry and Landing Investigations and Analysis (AMELIA) experiment was the assessment of the atmospheric science and landing site by exploiting the Entry Descent and Landing System (EDLS) sensors of Schiaparelli beyond their designed role of monitoring and evaluating the performance of the EDL technology demonstrator. Although more limited than expected, the flight data received from Schiaparelli are essential to investigate the anomaly that caused the crash landing and for the achievement of the AMELIA scientific objectives. We will present our methodology and results for the reconstruction of the dynamics of the vehicles during the EDL phases from the available flight data in order to assess the trajectory and attitude of the Schiaparelli EDM and to retrieve the atmospheric profiles.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132476718","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}
