Alternative 4D trajectories for the avoidance of weather- and contrail-sensitive volumes
(Single European Sky ATM Research (SESAR), 2022)
Conference report
Open AccessWe present a framework to generate, in a multi-aircraft environment, 4D optimized trajectories in a scenario with several weather constraints obtained with advanced weather prediction models. We focus on the trajectory ... -
Comparison of OpenFOAM turbulence models for numerical simulation of thermally-driven winds
(Budapest University of Technology and Economics, 2022)
Conference lecture
Open AccessCommercial computational fluid dynamics (CFD) codes have often been used for simulation of atmospheric boundary layer (ABL) flows. The present work explores the potential of the open-source CFD software OpenFOAM for ... -
Influence of axial air injection on the flame stability of a technically premixed hydrogen flame
(Global Power and Propulsion Society (GPPS), 2022)
Conference report
Open AccessThis work is a numerical investigation on the stability of a hydrogen flame in a swirl-stabilized burner configuration using large-eddy simulation with tabulated chemistry. Experimental results from this combustor showed ... -
On the impact of guidance commands mismatch in IMM-Based guidance modes identification for aircraft trajectory prediction
(2022)
Conference report
Open AccessThis study presents a sensitivity analysis to model mismatch of an interacting multiple model (IMM) filter when used for aircraft guidance modes identification. The mismatch appears in the guidance command parameters ... -
An acoustic technique for propellant gauging
(2022)
Conference report
Restricted access - publisher's policyThe gauging of propellants in upper stages or satellites in orbit is a challenging task due to the absence of buoyancy, which makes liquids and gases adopt a large variety of configurations. The new Spectral Mass Gauging ... -
Heat transfer management in propellant tanks
(2022)
Conference report
Restricted access - publisher's policyA critical issue in long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, and hot spots might appear on the tank walls ... -
Integrated acoustic technology for boil-off control, mass gauging, and structural health monitoring in cryogenic fuel tanks
(2022)
Conference report
Restricted access - publisher's policyLong-term space exploration missions require efficient systems for cryogenic propellant storage and management. The exposure of the fuel tanks to the in-space operational environment implies the need for efficient technologies ... -
Interferometric SAR deformation timeseries: a quality index
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
Conference report
Open AccessEstimating unknown absolute phase from a wrapped observation is a challenging and ill-posed problem that possibly leads to misinterpretation of interferometric SAR (InSAR) deformation results. In this study, we introduce ... -
A secure broadcast service for LDACS with an application to secure GBAS
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThe VHF Data Broadcast (VDB) data link is responsible for transmitting Ground Based Augmentation System (GBAS) corrections from the GBAS ground station to the aircraft. Thus, it is a major bottleneck for the evolution and ... -
LES study of the impact of fuel composition on a swirl spray flame approaching blow-off
(2021)
Conference lecture
Open AccessThe present paper focuses on the large eddy simulation (LES) of the n-heptane and n-dodecane flames of the Cambridge swirl flames data repository (Sidey et al., 2017). The applied tabulated chemistry spray combustion model ... -
Assessment of chemistry reduction in high-pressure spray flames of oxymethylene ethers using large-eddy simulations
(2021)
Conference lecture
Open AccessThis study is focused on the numerical investigation of reduced chemical schemes for high pressure spray flames of oxymethylene ethers (OMEx). A reduced mechanism using Path Flux Analysis (PFA) technique is tested using ... -
Detection of GNSS multipath with time-differenced code-minus-carrier for land-based applications
(IEEE Press ; Wiley, 2020)
Conference report
Open AccessGround transportation systems demand accurate and robust localizationfunctions. Satellite navigation is considered a key element in those systems, but its position determination can be highly corrupted in urban environments ...
