  • A Review and Gap Analysis of Exploiting Aerodynamic Forces as a Means to Control Satellite Formation Flight 

    Traub, Constantin; Romano, F.; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Using several small, unconnected satellites flying in formation rather than a single monolithic satellite has many advantages. As an example, separate optical systems can be combined to function as a single larger (synthetic) ...

  • Effects of applied magnetic field on IPG6-S, test-bed for an ABEP-based inductive plasma thruster (IPT) 

    Romano, Francesco; Herdrich, Georg; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (Association Aéronautique et Astronautique de France, 2018)

    An atmosphere-breathing electric propulsion system (ABEP) captures the residual atmosphere of a planet and uses it as propellant for an electric thruster to counteract the drag. The system would theoretically allow orbiting ...

  • Fluidic actuator performance variation via internal dimensions modifications 

    Baghaei, Masoud; Bergadà Granyó, Josep Maria; Campo Sud, David del (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    When aimed to modify the downstream vortex shedding of a given bluff body, whether any road vehicle or wing profile, the use of Active Flow Control (AFC) appears to be an efficient technology. Among the different (AFC) ...

  • Research on fluidic amplifiers dimensional modifications via computer simulation (CFD) 

    Baghaei, Masoud; Bergadà Granyó, Josep Maria; Campo Sud, David del; Campo Gatell, Vanessa del (Istanbul Tecnical University, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    When studying active flow control applications, it is already stated that activating the boundary layer via using periodic flow produces better performance than when employing steady blowing or sucking. This is why studying ...

  • Successes and challenges of a collaborative-PBL program in engineering degrees 

    González Vila, Joaquin; Font Andreu, Jorge; Salán Ballesteros, Maria Núria; García-Almiñana, Daniel; Ortiz Marzo, José Antonio; Mudarra López, Miguel; Griful Ponsati, Eulàlia (2012-02-02)
    Text en actes de congrés
    Accés obert
    This paper presents an extracurricular program called INSPIRE3 that has been implemented by the ETSEIAT (Escola Tècnica Superior d’Enginyeries Industrial i Aeronàutica de Terrassa), a center belonging to the UPC-BarcelonaTech ...

  • Review of Lambert's problem 

    Torre Sangrà, David de la; Fantino, Elena (2015)
    Comunicació de congrés
    Accés obert
    Lambert’s problem is the orbital boundary-value problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ...

  • Analysis of perturbations and station-keeping requirements in highly-inclined geosynchronous orbits 

    Fantino, Elena; Flores Le Roux, Roberto Maurice; Di Salvo, Alessio; Di Carlo, Marilena (2015)
    Text en actes de congrés
    Accés obert
    There is a demand for communications services at high latitudes that is not well served by conventional geostationary satellites. Alternatives using low-altitude orbits require too large constellations. Other options are ...

  • Modelling harmonics drawn by nonlinear loads 

    Lamich Arocas, Manuel; Balcells Sendra, Josep; Mon González, Juan; Corbalán Fuertes, Montserrat; Griful Ponsati, Eulàlia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper is devoted to obtain a model of nonlinear loads (NLL) connected to LV electric networks, in order to predict the consequences of including parallel active or passive filters. The model is based on Neural ...

  • Preliminary study on fluidic actuators. Design modifications 

    Campo Sud, David del; Bergadà Granyó, Josep Maria; Campo Gatell, Vanessa del (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    As fluidic actuators have the advantage of lacking moving parts, their use in real applications brings high reliability. This is why, once having overcome their drawbacks, which means being able to provide the appropriate ...

  • A simulation tool for parachute/payload systems 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique; Vallés Fluvià, J.; Oñate Ibáñez de Navarra, Eugenio (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The design and evaluation of parachute-payload systems is a technology field in which numerical analysis tools can make very important contributions. This work describes a new development from CIMNE in this area, a coupled ...

  • Multidisciplinary study of tutoring using virtual characters and second life 

    Amante García, Beatriz; Campo Sud, David del; Martínez Martínez, María del Rosario (2012)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this article we present the planning and methodology followed in order to apply virtual tutoring sessions in different subjects and universities. The Second Life environment, together with the Voki speaking avatars will ...
