This paper presents a study on a new tuneable material for vibration control purposes. The material is formed by a structured fabric wrapped in a deflated bag. The fabric is made of an interwoven mesh of rigid truss-like particles. The vacuum inside the casing produces a jamming effect. Hence, the elasticity and damping of the packaged fabric can be tuned by changing the level of vacuum in the bag. This material can be conveniently employed to develop new vibration control treatments and devices. In this respect, the paper first presents the tests carried out with a six-point bending machine to characterise the static and dynamic stiffness of the material as well as its damping properties. Then it demonstrates an application, where the material is used as a tuneable vibration absorber.","PeriodicalId":87445,"journal":{"name":"Materials Research Society symposia proceedings.

The paper presents the main characteristics of the high flux solar simulator facility designed and developed at University of Padova as key enabling technology to evaluate the effectiveness of satellite hardware for missions to the inner planets of the Solar System. The designed solar simulator can reproduce the intensity and spectral distribution of the Sun's radiation up to 8 Solar constants (around 10000 Watt/m2) and the emitted flux can be directed to the viewport of a Thermal Vacuum Chamber in order to test the performance of space equipment under representative pressure and temperature conditions. Angles of incidence between 30° and 90° can be achieved using a motorised setup within the thermal chamber while different intensities of sunlight can be obtained by properly choosing the emitting lamp and regulating the electric power. After the verification of optical path alignment, a series of tests has been conducted to evaluate the flux homogeneity installing a commercial pyranometer on cartesian reference and moving the slide within the target area. A final Class A classification for the spatial non-uniformity of irradiance as for ASTM E927-19 has been achieved for the central target area. The facility has afterwards operated for validation campaign of satellite radiators in simulated orbital condition, verifying the repeatability of reproduced flux during continuous long-term operation.","PeriodicalId":87445,"journal":{"name":"Materials Research Society symposia proceedings.

The paper is focused on the development of a modelling approach for Ceramic Matrix Composites (CMC) laminates, produced through a cost-affordable Liquid Silicon Infiltration (LSI) technique. The objective is the development of a tool capable of evaluating the design values for the material in the presence of technological defects and complex geometrical features, which could be used at the level of structural elements of details of reusable space vehicles. The model exploits a bi-phasic decomposition to capture four important aspect of the material: the non-linear behaviour occurring when load is not applied in the fibre direction, the significant bending to tensile strength ratio, the role of matrix fractures in the failure process and the role of delamination phenomena in the response. The correlation with tensile and bending tests performed with different lay-ups indicates that the developed approach can fulfil such objectives and may be used in the definition of structural details and of damage tolerance of innovative space vehicles.","PeriodicalId":87445,"journal":{"name":"Materials Research Society symposia proceedings.

In the recent years, the field of unmanned aircraft vehicles (UAVs) has shown great technological progresses and many new applications have born. To assess the potential of this technology and to improve the availability and reliability of the rising services it is critical to overcome operational limitations. One key operational hazard is atmospheric in-flight icing, resulting in large aerodynamic penalties, unbalances and other detrimental phenomena that sometimes can lead to catastrophic consequences. In this paper, a new ice tunnel developed in the large hypobaric and climatic chamber of the terraXcube facility of Eurac will be presented. A preliminary characterization and calibration of the system has been also performed following the EASA regulation reported in the Easy Access Rules for Large Rotorcraft (CS-29) (Amendment 6).","PeriodicalId":87445,"journal":{"name":"Materials Research Society symposia proceedings.

DOCKS is a smart docking system for space vehicles developed by the Department of Industrial Engineering, University of Padova, within the framework of the Space Rider Observer Cube (SROC) mission. The design and development of SROC is being conducted by a consortium of Italian entities under contract with the European Space Agency (ESA). The SROC mission is designed to be a payload on the ESA Space Rider (SR) spaceship. The main objective of the mission is to demonstrate the critical capabilities and technologies required to execute a rendezvous and docking mission in a safety-sensitive context. The space system is composed by a nanosatellite (approximately 12U CubeSat) and a deployment/retrieval mechanism mounted inside the payload bay of SR. During the mission, SROC will be released by SR, will perform inspection manoeuvres on SR and, at the end of the mission, will dock back inside the bay of SR, before re-entering Earth with the mothership. The docking functionality is provided by DOCKS. DOCKS is suitable for use onboard micro- and nanosatellites and merges a classical probe drogue configuration with a gripper–like design, to manage the connection between the parts. The system is equipped with a suite of sensors to estimate the relative pose of the target and with a dedicated computer, making it a smart standalone system. A laboratory prototype has been assembled and functionally tested, aiming at the validation of the capability to passively manage misalignments during the docking manoeuvre.","PeriodicalId":87445,"journal":{"name":"Materials Research Society symposia proceedings.
