Drop-weight experiments studied the damages due to repeated low-velocity impacts of hybrid composite laminates. The laminate made by carbon woven fabric and glass woven fabric impregnated by vinyl ester resin was subjected at single impact, at 5 repeated impacts and 10 repeated impacts, for an energetic level of U=20J. The final damage after the single and repeated impact events was analysed by no-destructive methods, Pulse Thermography and Holographic Interferometry to evaluate the influence of the multi-hit events on the damaged area's evolution.

This paper proposes a novel covariance-scaling based robust adaptive Kalman filter (RAKF) algorithm for attitude (i.e., roll and pitch) estimation using an inertial measurement unit (IMU) composed of accelerometer and gyroscope triads. KF based and complementary filtering (CF) based approaches are the two common methods for solving the attitude estimation problem. Efficiency and optimality of the KF based attitude filters are correlated with appropriate tuning of the covariance matrices. Manual tuning process is difficult and time-consuming task. The proposed algorithm provides an adaptive way for tuning process and it can accurately estimate the attitude in two axes. The proposed methodology is tested and compared with other existing filtering methodologies in the literature under different dynamical conditions and using real-world experimental dataset in order to validate its effectiveness.

Cognitive Radar (CR) is a new paradigm to design the next radar generation in accordance to criterions inspired to mental abilities related to knowledge. This approach is thought to dramatically improve the current generation of systems as it leverages the adaptivity of the sensor to the changing environments in which radars operate. The sections that follow illustrate how the Digital Array Radar (DAR) and advanced digital signal processing might be the enabling system architecture and technologies to implement a CR. In this regard, Adaptive Beam Forming (ABF) algorithms, which adaptively suppress possible interferences impinging on the array antenna, are one of the key features CR should possess to minimize the jammers and maximize the performances. Possible implementations of two ABF architectures and three algorithms are analyzed, and their performances evaluated in the case of analogue inter-channel receiver mismatch present among the receivers. In greater detail, two algorithms leveraging the DAR architecture are analyzed and their performances evaluated against the analogue formed beams approach that was used in the previous generation of radar sensors. The performances of the three algorithms are assessed as far as cancellation capability of both main beam jammer and sidelobe jammer is concerned, in presence of inter-channel phase and amplitude mismatches among the analogue receivers.

Exploration of deep space can lead to several health problems due to exposure to cosmic radiation. To increase health and safety in interplanetary exploratory missions, passive shielding is considered the best solution, though not without faults. In fact, shielding can be complex for several reasons, such as the deficiency in biological and physical measurements. Another fundamental aspect related to the shielding problem is the space radiation environment. In fact, galactic cosmic rays, solar particle events, and trapped particle radiations are considered some of the major health risk to astronauts. To protect the space crew, both passive and active shielding is used. In particular, the passive method is considered more efficient to limit the absorbed dose. Fundamental is also the choice of the shielding material. In fact, some materials, like polyethylene, is deemed one of the most effective tools against space radiation.

MicroMED is an Optical Particle Counter (OPC) on board the ExoMARS 2022 lander. It aims to perform the first direct monitoring of the martian suspended dust, measuring grain concentration and size distribution. In an OPC single dust grains are sampled in an illuminated spot and their size is retrieved based on the amplitude of the scattered light signal. In this study we analyze the possibility to determine the grain size using an alternative approach based on the durations of the signals rather than their magnitude. For this purpose, we studied the motion of the sampled grains by using a Computational Fluid Dynamic (CFD) simulation, to assure the consistency of the method. We have then performed a laboratory test campaign in martian simulated environment, to measure the signal durations relative to different monodispersed samples. The test results are here presented and compared with the numerical ones obtained using the CFD simulations. Using the acquired data, we present a preliminary duration-diameter calibration function, discussing the pros and cons of this method and how it can support the standard OPC one based on the signal magnitude.

The following work presents a study based on spontaneous emission spectroscopy that evaluates the average temperatures of the plasma shock layer next to the solid surface and of the test article surfaces subject to the hypersonic jet determined by Scirocco Plasma Wind Tunnel (PWT) at CIRA. The SCIROCCO arcjet plasma tunnel, is the most powerful PWT in the world used to test the materials of TPS (Thermal Protection System) in the atmospheric entry phase. The methodology focuses on the radiation emitted by the test article in the VIS- NIR (i.e. Visible- Near Infrared) spectral ranges, from which the surface temperature and the emissivity values can be obtained. A UV nikkor camera connected to a compact spectrometer framed the lateral side of a C/SiC test article flap, subject to a known PWT fluid-dynamic flow condition expressed in terms of total pressure P0, total enthalpy H0 and air mass flow rate. A spectrometer with sizes of centimetres was used. It consisted of a commercially available Ocean Optics USB 2000, characterized by no moving parts and no cooling sensor with a 600 gr/mm diffraction grating.

In this work, the optimization of the optical bench for the MicroMED dust analyzer is presented. A nonconventional design technique has been exploited to obtain a mass saving, valuable achievement in aerospace and space instruments design. Topology optimization has been coupled to the finite element approach to improve the optical bench design, whose performance has been assessed and compared with the actual one. The optimization results proved the robustness of the adopted workflow and provided interesting results for a possible design enhancement of the MicroMED dust analyzer. A saving of about 55% of the available design domain mass budget has been achieved, and the dynamic behavior of the structural component has been improved, providing about 50% increase of the first eigenfrequency value.

In many Space Surveillance and Tracking (SST) operations, from the cataloguing of trackable space objects to orbit determination and correlation, ground-based measurements play a central role. In this frame, the monitoring and, if necessary, the update of the sensors' calibration parameters is of utmost importance to correctly evaluate the positions of tracked objects. In this work, a method for the metrological characterization of ground-based sensors for SST applications is implemented, and the performance of the developed sensor calibration tool is assessed. Starting from the acquisition of information about the sensor and data from Tracking Data Messages and Orbit Ephemeris Messages, and assuming a Gaussian distribution for all the observed parameters, the tool computes the residuals and outputs the main statistics for all the parameters of interest. The distributions of the residuals are analyzed to evaluate the statistical significance of the results and the robustness of the hypothesis of Gaussian distribution.
