    The Engine Combustion Network (ECN) spray A under diesel engine conditions is investigated with a non-adiabatic 5D Flamelet Generated Manifolds (FGM) model with the consideration of detailed chemical kinetic mechanisms. ...
  • Multiple UAV systems: a survey 

    Skorobogatov, Georgy; Barrado Muxí, Cristina; Salamí San Juan, Esther (2020-04-02)
    Article
    Open Access
    Nowadays, Unmanned Aerial Vehicles (UAVs) are used in many different applications. Using systems of multiple UAVs is the next obvious step in the process of applying this technology for variety of tasks. There are few ...

    Fuel consumption is one of the major considerations for both the impact of aviation in the environment and the cost of operations. This paper assesses the accuracy of a method capable of producing aircraft fuel estimates ...
  • A framework for collaborative air traffic flow management minimizing costs for airspace users: Enabling trajectory options and flexible pre-tactical delay management 

    Xu, Yan; Dalmau Codina, Ramon; Melgosa Farrés, Marc; Villardi de Montlaur, Adeline de; Prats Menéndez, Xavier (2020-03-03)
    Article
    Restricted access - publisher's policy
    This paper proposes a collaborative air traffic flow management (ATFM) framework, in the scope of trajectory based operations, aiming to improve the cost-efficiency for airspace users (AUs) when facing ATFM regulations. ...
  • Using Broadcast Wind Observations to Update the Optimal Descent Trajectory in Real-Time 

    Dalmau Codina, Ramon; Prats Menéndez, Xavier; Baxley, Brian (2020-02)
    Article
    Restricted access - publisher's policy
    The ability to meet a controlled time of arrival during a continuous descent operation will enable environmentally friendly and fuel-efficient descent operations while simultaneously maintaining airport throughput. However, ...
  • Measuring phase scintillation at different frequencies with conventional GNSS receivers operating at 1 Hz 

    Nguyen, Viet Khoi; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Hai Tung, Ta; The Vinh, La (2019-10-01)
    Article
    Open Access
    Ionospheric scintillation causes rapid fluctuations of measurements from Global Navigation Satellite Systems (GNSSs), thus threatening space-based communication and geolocation services. The phenomenon is most intense in ...
  • Assessing the quality of ionospheric models through GNSS positioning error: methodology and results 

    Rovira Garcia, Adrià; Ibáñez Segura, Deimos; Orús Pérez, Raul; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo (2020-01-01)
    Article
    Open Access
    Single-frequency users of the global navigation satellite system (GNSS) must correct for the ionospheric delay. These corrections are available from global ionospheric models (GIMs). Therefore, the accuracy of the GIM is ...
  • Confirming geomagnetic Sfe by means of a solar flare detector based on GNSS 

    Curto Subirats, Juan Jose; Juan Zornoza, José Miguel; Timote Bejarano, Cristhian Camilo (2019-11-28)
