R.E.A.C.T - Innovation Booster Living Labs for Decarbonisation
AGP

Rolle: Hauptgesuchsteller/in

Description du projet : R.E.A.C.T. is dedicated to transforming urban mobility for businesses. Our vision is to provide a comprehensive, modular platform comprising an electric bicycle trailer and an array of logistics solutions. This innovative ecosystem is designed to empower companies to eliminate the reliance on cumbersome, costly, and space-inefficient vehicles in urban environments, paving the way for a more efficient and decarbonized future. Traffic in cities are becoming more and more a problem for citizen and the company who need to navigate inside them. The actual solution consist of either commercial vehicles or trucks, but they are really expensive to operate, space consuming, more subject to small maneuvering accident, and just unpractical to use in cities. Cargobike are emerging, but lack of appropriate infrastructure and modularity make them inefficient. With R.E.A.C.T., we aimed to create the perfect urban mobility ecosystem, composed of an electric bike trailer, a box, that can be mounted on the trailer, or drop after transportation and a pick-up point, a temporary storage unit placed around the city to store the boxes.

Remorque active de vélo pour le transport de colis - REACT
AGP

Rolle: Hauptgesuchsteller/in

Description du projet : Assurer l'arrivage des colis jusqu'à leur site d'expédition. L'entreprise Kargobike est spécialisée dans la livraison de colis par vélo-cargo. Elle utilise actuellement des vélos spéciaux possédant une zone de charge pour les colis à transporter. La société sédunoise délivre des colis à des tarifs plus compétitifs que les autres acteurs du secteur dans les villes de Sion et Martigny et ce de la manière la plus écologique du marché, à la force des jambes de ses employés. La conduite de vélo-cargo avec ou sans remorque demande des compétences de pilotage particulières, limitées à une élite de pilotes de vélo possédant une grande expérience du domaine. Ainsi, la position de la charge n'est pas habituelle et ne correspond à ce que l'on connait lors de l'utilisation de vélo standard. Par ailleurs, cette position change lors du chargement et tout au long du déchargement induisant une modification constante du comportement dynamique routier du vélo qu'il faut anticiper en tout temps. Un système de remorque active pour vélo avec une motorisation réellement efficace permettra d'engager des conducteurs de vélo sans talents spécifiques car une conduite habituelle sera alors retrouvée. Ouvrant la porte au plus grand nombre et créant par là-même des emplois supplémentaires dans ce secteur, cela permettra une remise à niveau de la rentabilité de l'activité, une augmentation significative de sa résilience ainsi qu'une plus grande adaptabilité de face aux crises futures. Ce projet sera de plus une première étape d'une vision d'avenir où l'attelage de plusieurs remorques en 'train', couplée à une distribution en modules indépendants déposés ici et repris là, offrant une solution stratégique disruptive de distribution de colis de proximité et à grande échelle.

The STEAMR Instrument: Optical Design, Development & Testing
Wissenschaftlicher Artikel

Paciotti Gabriel

23RD INTERNATIONAL SYMPOSIUM ON SPACE TERAHERTZ TECHNOLOGY, TOKYO, 2012

Link zur Publikation

Zusammenfassung:

The STEAMR instrument is a Swedish national
contribution to the ESA PREMIER mission, which is a candidate
for the upcoming Earth Core Explorer mission. The STEAMR
instrument is envisaged as a multi-beam limb sounding satellite,
which will utilise 14 simultaneously observing beams in two 12
GHz wide bands from 323 to 357 GHz. To maximize spatial
sampling in the elevation direction the observing beams have
an elliptical geometry, which defines the incoming beams as
being astigmatic. In this paper we present an antenna optics
scheme which corrects for this inherent astigmatism, thereby
ensuring optimum imaging of the incoming to the circularly
symmetric receiver feed horns. Furthermore, the design, synthesis
and electromagnetic verification of a prototype focal plane array
for the STEAMR instrument is also reported.

Link zur Konferenz

Zusammenfassung:

Pyrovalves, i.e., valves actuated by a pyrotechnical device, are very often used in space propulsion systems for their fast response, high reliability, low mass and low cost. However, they are hazardous and single use items. Their operation induces shocks and can generate contaminants. If a slower actuation is required or possible, shape memory-based actuators avoid the generation of shocks and contaminants while being fully resettable and non-hazardous devices. The goal of this project was to develop a bi-stable Shape Memory Alloy (SMA) actuator for a specific Slow Acting Latch Valve with long life capability. The benefits of this actuator makes it interesting not only for valve actuation but also for any device that has to be actuated in a smooth and reliable way. This paper presents the development of a bi-stable actuator based on high temperature shape memory alloys.

Development and preliminary testing of a high precision long stroke slit change mechanism for the SPICE instrument

Proceedings of the 42nd Aerospace Mechanisms Symposium

Link zur Konferenz

Zusammenfassung:

In the frame of ESA’s Solar Orbiter scientific mission, Almatech has been selected to design, develop and test the Slit Change Mechanism of the SPICE (SPectral Imaging of the Coronal Environment) instrument. In order to guaranty optical cleanliness level while fulfilling stringent positioning accuracies and repeatability requirements for slit positioning in the optical path of the instrument, a linear guiding system based on a double flexible blade arrangement has been selected. The four different slits to be used for the SPICE instrument resulted in a total stroke of 16.5 mm in this linear slit changer arrangement. The combination of long stroke and high precision positioning requirements has been identified as the main design challenge to be validated through breadboard models testing. This paper presents the development of SPICE’s Slit Change Mechanism (SCM) and the two-step validation tests successfully performed on breadboard models of its flexible blade support system.

Collaborateurs: Paciotti Gabriel

Link zur Errungenschaft

These samples, made of Nickel Titanium alloys, will be exposed to the harsh space environment for nearly a year before their scheduled return with the SpaceX mission 33, in december 2025.

The experiment aims to study the ageing of the materials in Low Earth Orbit (LEO) to assess their suitability for space machanisms ans actuators. Developed through a collaboration between Mechanical Design Research Group and the Powder Technology and Advanced Material Group, these materials possess shape memory and superelestaicity properties, making them extremly promising for design the next generation of higly reliable actuators for space applications
