This course provides an overview of recent developments in sound transmission control through aeronautical panel structures. In the first part, general definitions of the sound transmission efficiency parameters are given; moreover, the classical and advanced structural models used to analyze sandwich structures are depicted. In the second part of the course, the attention is focused on recent industrial interests such as 3d-printed lattice materials used for the design of sandwich cores, the homogenization of the lattice material properties is introduced. Furthermore, the passive damping of the multilayered panels can be improved by using soft viscoelastic materials; therefore, their modelling with classical Kelvin-Voigt or fractional derivatives models is explained. In the last part of the course, the structural optimization problem is introduced; the original contributions of the authors define a new particle swarm optimization model called the Population Decline Swarm Optimization method. Finally, some case studies concerning the sound transmission control through optimized multilayered shell composite sandwich panels with lattice core embedding viscoelastic sheets are discussed.

The main instruments for the development and attraction of research talent to the European Union (EU) are the European Research Council (ERC) and the Marie Skłodowska-Curie Actions (MSCA). Over the last decade, the ERC and the MSCA funded wide and diverse areas of research relevant to the aerospace sector and gave many researchers the opportunity to develop their projects with highly competitive conditions.

In the first part of the course, EU scientific officers and experts will give an overview of the main characteristics and opportunities offered by the ERC and MSCA funding schemes. Particular attention will be given to the mission, funding, and evaluation process.

In the remaining part of the course, authors of successful ERC and MSCA-PF grant proposals on topics of aerospace relevance will present their own stories and projects and will give the audience their insight and advice on the application process. Details on lessons learned, proposal writing, preparation of the curriculum vitae, and stage-2 interview will be discussed along with eventual opportunities to join an ERC team.

The webinar deals with an introduction to the world of flight simulators employed as research platforms and not exclusively as training tools. The main simulator levels, recognized by the EASA, European Union Aviation Safety Agency, will be firstly described focusing on FFS (Full Flight Simulator). Then, the main research contexts, taking advantage of flight simulators, will be presented with some referenced research activities. This will be followed by the description of research topics concerning the human factor and comfort in the simulated environments of cockpit and cabin.

Firstly, the objective and subjective techniques used to evaluate the aeronautical human factor will be described. Next, the main subjective tests for real-time and post-tasks are given, evaluating the main advantages and drawbacks. Then, objective measurement based on existing technologies will be introduced, particularly sensors exploitable inside the aircraft. Also, for these techniques, the main advantages and drawbacks will be shown. Finally, a brief overview of the mathematical correlation tools that can relate the two types of measurement data will be presented with reference to some experimental study cases.

In the second part of the course, the research topic of aviation comfort will be introduced. First, the human body’s biodynamic modelling techniques will be described with an overview of the models employed in the aeronautical framework, followed by experimental results. Finally, the analytical and numerical modelling will be shown with examples of evaluation on the human body’s comfort indexes with aeronautical manufacturers’ restrictions.

Learning objectives: Simulator classification, standards, and experimental research activities; Human Factors in cockpit and cabin environment; Human Body Comfort for pilot and passenger.

Target audience: doctoral students, non-academic professionals, and undergraduate students.

This webinar introduces the design of orbits for Low Earth Orbit (LEO) nanosatellites and nanosatellite’s constellations to maximise local transmission or coverage capacity with a limited number of satellites. It will describe the main drivers in determining orbital evolution in Low Earth Orbit considering the perturbed two-body problem of Keplerian orbital dynamic and deriving the expression for repeated ground track and revisit time considering different coverage or visibility conditions with multiple ground stations. Finally, the webinar will present the application of orbit analysis investigations to maximise the visibility of single satellites from multiple ground stations and optimise local coverage patterns using special architectures for regional constellation design (Walker and flower constellations) aimed at continuous optical and SAR monitoring of large infrastructures.

Learning objectives:

• Classical and perturbed two-body orbital flight dynamics;
• Repeated ground track orbits and revisits time calculation;
• Regional constellation design.

Target audience: doctoral students interested in Earth orbit nanosat constellations design, engineers who aspire to a deeper understanding of applied orbital dynamics, technical or non-technical professionals new to the space industry who need an introduction to the problem of orbital design in LEO.

Deliver robotic platforms and, in the next future, human missions on a planetary body with an atmosphere is a significant technological challenge. Onboard data acquired during Entry Descent and Landing (EDL) mission phases are typically used to verify the engineering system performances. Nevertheless, such data carry out much information of great scientific value. This webinar introduces the post-flight analysis of EDL mission data with a particular focus on the reconstruction of atmospheric profiles building upon the experience with past missions such as Huygens end ExoMars-2016 and presenting real-world case studies.

Topics:

• Introduction to entry, descent and landing technologies with related onboard instrumentation. Overview of past and future planetary exploration missions.
• Basic aerodynamics of aeroshells and parachute systems, guidance, navigation and control issues.
• Entry and descent phase modelling and simulation. Case study: ExoMars-2022 entry and descent simulation.
• Methods and algorithms for the reconstruction of trajectory and atmospheric profiles from onboard data. Bayesian techniques for data assimilation. Case study: ExoMars-2016 Schiaparelli data analysis.

Learning objectives:

• Understand EDL challenges and current technologies.
• Understand aeroshell and parachute aerodynamic, dynamical modelling and entry and descent phases simulation issues.
• Implement methods and algorithms to reconstruct both the vehicle trajectory and the atmospheric structure from inertial data.
• Application of Bayesian techniques for data assimilation and multi-sensor fusion.

Target audience: doctoral students, non-academic professionals, and undergraduate students.
