Discrete-Variable-Thrust Guidance for Orbital Rendezvous Based on Feedback Linearization
Aerotecnica Missili & Spazio - Tập 101 - Trang 351-360 - 2022
I. Napoli, M. Pontani
This research is focused on the analysis, design, and numerical testing of a feedback guidance algorithm for autonomous (unmanned) close-range maneuvering of a chaser spacecraft, in the context of orbital rendezvous with a target vehicle. The relative dynamics of the two vehicles, placed in nearby low Earth orbits, is modeled using the nonlinear Battin–Giorgi equations of relative motion, with the...... hiện toàn bộ

Gain Selection for Attitude Stabilization of Earth-Pointing Spacecraft Using Magnetorquers
Aerotecnica Missili & Spazio - Tập 100 Số 1 - Trang 15-24 - 2021
Fabio Celani
AbstractThis paper considers a feedback control law that achieves attitude stabilization for Earth-pointing spacecraft using only magnetorquers as torque actuators. The control law is proportional derivative (PD)-like with matrix gains, and it guarantees asymptotic stability. The PD matrix gains are determined through the numerical solution of a periodic linear qua...... hiện toàn bộ
The Nutriss Study: A New Approach to Calibrate Diet and Exercise in Long-Term Space Missions to Maintain Body Fat, Muscle and Fluid Homeostasis
Aerotecnica Missili & Spazio - Tập 99 - Trang 121-125 - 2020
F. G. Di Girolamo, G. Biolo, N. Fiotti, R. Situlin, C. Piacenza, P. Lepore, R. Fortezza, E. Carrubba, C. Pacelli, G. Valentini, G. Mascetti, S. Piccirillo
Energy balance maintenance is crucial to preserve astronaut’s wellness and quality of life during long-duration spaceflight and nutritional intervention can effectively counteract the detrimental effect of microgravity on skeletal muscle mass and metabolism. NutrISS (Nutrition monitoring for the International Space Station) is an Italian Space Agency (ASI) biomedical experiment investigating the c...... hiện toàn bộ
ADCS Design for a Sounding Rocket with Thrust Vectoring
Aerotecnica Missili & Spazio - Tập 102 Số 3 - Trang 257-270 - 2023
Pedro Santos, Paulo J. Oliveira
AbstractThis paper addresses the development of an attitude determination and control system (ADCS) for a sounding rocket using thrust vector control (TVC). To design the ADCS, a non-linear 6 degrees-of-freedom (DoF) model for the rocket dynamics and kinematics is deduced and implemented in simulation environment. An optimal attitude controller is designed using th...... hiện toàn bộ
An Experimental and Numerical Study of the Aerodynamic Interaction Between Tandem Overlapping Propellers
Aerotecnica Missili & Spazio - Tập 102 - Trang 77-89 - 2022
Davide Algarotti
The latest trends of Urban Air Mobility pushed the aeronautical industrial sector towards the eVTOL concept, i.e. electrical vertical take-off and landing. Electrical power, tilt-wing configuration and multiple propellers in tandem configuration, i.e. with the propellers placed one after the other, are the key features of such concept. In particular, the presence of multiple propellers working at ...... hiện toàn bộ

Space Environment Effect on Polymeric Nano-Composite Materials
Aerotecnica Missili & Spazio - Tập 100 - Trang 25-32 - 2021
A. Delfini, A. Anwar, R. Pastore, L. Bassiouny, M. Marchetti, F. Santoni
Several kinds of polymeric nano-composites were fabricated by including different typologies of nano-size fillers into a commercial epoxy matrix. The employed additives are: multi-walled carbon nanotubes (MWCNTs), alumina (AL2O3) nanoparticles, and three types of graphene platelets (G-CD270, G-33C and G-24N). The effect of the exposition to low earth orbit (LEO) space threats on the candidate nano...... hiện toàn bộ
Launch of an Innovative Air Pollutant Sampler up to 27,000 Metres Using a Stratospheric Balloon
Aerotecnica Missili & Spazio - Tập 102 - Trang 127-138 - 2023
Federico Toson, Mauro Pulice, Marco Furiato, Matilde Pavan, Simone Sandon, Dumitrita Sandu, Giovanni Righi
Air pollution, besides being one of the leading causes of death worldwide, remains one of the most controversial topics in environmental monitoring. The current state of the art refers to remote satellite analysis and static ground-level technologies. The O-ZONE project has set itself the objective of bridging this technological gap using dynamic in situ analysis using compact, inexpensive and reu...... hiện toàn bộ
A Deep Learning Strategy For On-Orbit Servicing Via Space Robotic Manipulator
Aerotecnica Missili & Spazio - Tập 98 - Trang 273-282 - 2019
A. Stolfi, F. Angeletti, P. Gasbarri, M. Panella
Autonomous robotic systems are currently being addressed as a critical element in the development of present and future on-orbit operations. Modern missions are calling for systems capable of reproducing human’s decision-making process, thus enhancing their performance. Generally, space manipulators are mounted on a floating spacecraft in a microgravity environment, consequently leading to a mutua...... hiện toàn bộ
