    The Galileo High Accuracy Service (HAS) is a new capability of the European Global Navigation Satellite System that is currently under development. The Galileo HAS will start providing satellite orbit and clock corrections ...
  • Sensitivity analysis of maximum circulation of wake vortex encountered by en-route aircraft 

    Rojas Gregorio, José Ignacio; Melgosa Farrés, Marc; Prats Menéndez, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-16)
    Article
    Open Access
    Wake vortex encounters (WVE) can pose significant hazard for en-route aircraft. We studied the sensitivity of wake vortex (WV) circulation and decay to aircraft mass, altitude, velocity, density, time of catastrophic wake ...
  • Flows between orthogonally stretching parallel plates 

    Ayats López, Roger; Marqués Truyol, Francisco; Meseguer Serrano, Álvaro; Weidman, Patrick (2021-02-01)
    Article
    Open Access
    Navier–Stokes equilibrium solutions of a viscous fluid confined between two infinite parallel plates that can independently stretch or shrink in orthogonal directions are studied. It is assumed that the admissible solutions ...
  • A Fast and flexible emergency trajectory generator : enhancing emergency geometric planning with aircraft dynamics 

    Sáez García, Raúl; Khaledian, Homeyra; Prats Menéndez, Xavier; Guitart, Andréas; Delahaye, Daniel; Feron, Eric (2021)
    Conference report
    Open Access
    We present an automated emergency trajectory generator to compute the best emergency trajectory for a given landing site. A combination of the optimized version of the rapidly exploring random tree algorithm and Dubins ...
  • Generation of emergency trajectories based on aircraft trajectory prediction 

    Sáez García, Raúl; Khaledian, Homeyra; Prats Menéndez, Xavier (2021)
    Conference report
    Restricted access - publisher's policy
    We present an automated emergency trajectory generator to compute the best emergency trajectory for a given landing site. A given emergency 2-dimensional (2D) path (i.e., route) is used as input for a trajectory predictor ...
  • Automated sequencing and merging with dynamic aircraft arrival routes and speed management for continuous descent operations 

    Sáez García, Raúl; Polishchuk, Tatiana; Schmidt, Christiane; Hardell, Henrik; Smetanová, Lucie; Polishchuk, Valentin; Prats Menéndez, Xavier (2021-11)
    Article
    Open Access
    In this paper, we present a novel methodology to manage arrival traffic in terminal airspace. We define two areas around the airport, aiming to efficiently schedule incoming traffic. A four-dimensional (4D) trajectory ...
  • Acoustic effects on heat transfer on the ground and in microgravity conditions 

    Quintana Buil, Guillem; González Cinca, Ricardo (2021-10)
    Article
    Open Access
    A critical issue in future long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, which can generate hot spots on the ...
  • Analysis of ‘Pre-Fit’ Datasets of gLAB by Robust Statistical Techniques 

    Alonso Alonso, María Teresa; Ferigato, Carlo; Ibáñez Segura, Deimos; Perrotta, Domenico; Rovira Garcia, Adrià; Sordini, Emmanuele (MDPI AG, 2021-05-24)
    Article
    Open Access
    The GNSS LABoratory tool (gLAB) is an interactive educational suite of applications for processing data from the Global Navigation Satellite System (GNSS). gLAB is composed of several data analysis modules that compute the ...
  • Optimization of the progress variable definition using a genetic algorithm for the combustion of complex fuels 

    Both, Ambrus; Mira Martínez, Daniel; Lehmkuhl Barba, Oriol (MCM, 2021)
    Conference lecture
    Open Access
    In this work counterflow diffusion flamelets of n-heptane and air are used at stable and unsteady extinguishing conditions for building a thermo-chemical database for Computational Fluid Dynamics (CFD) calculations. The ...
  • High-fidelity simulations of the mixing and combustion of a technically premixed hydrogen flame 

    Mira Martínez, Daniel; Both, Ambrus; Lehmkuhl Barba, Oriol; Gomez Gonzalez, Samuel; Forck, Jonathan; Tanneberger, Tom; Stathopoulos, Panagiotis; Paschereit, Christian Oliver (MCM, 2021)
    Conference lecture
    Open Access
    Numerical simulations are used here to obtain further understanding on the flashback mechanism of a technically premixed hydrogen flame operated in lean conditions. Recent work from the authors (Mira et al., 2020) showed ...
  • Semi implicit solver for high fidelity LES/DNS solutions of reacting flows 

    Surapaneni, Anurag; Mira Martínez, Daniel (MCM, 2021)
    Conference lecture
    Open Access
    A semi-implicit/point-implicit stiff solver (ODEPIM) for integrating chemistry in context of high fidelity LES/DNS simulations is presented. A detailed overview of the algorithm and its numerical formulation is discussed. ...
