A numerical solver to assess the impact of wind, geometry, and altitude on artificial charge control of aircraft using corona discharge
(2022)
Conference report
Restricted access - publisher's policyPrior work by members of the team has shown that active charge control might reduce the risk of aircraft-triggered lightning. Controlling the net charge of an aircraft can be achieved by using corona discharge. For a ... -
Aircraft Charging and its Influence on Triggered Lightning
(2020-01-16)
Article
Open AccessThis paper reports on a laboratory experiment to study the effect of vehicle net charge on theinception of a positive leader from an aircraft exposed to high atmospheric electric fields. The experimentmodels the first stage ... -
Corona discharges from grounded rods under high ambient electric field and lightning activity
(2021)
Conference report
Open AccessWe assess results of corona pulses detected under high background electric field in the laboratory and in the field in two different experimental sites. The first location is on the roof of a regular building, and the ... -
Experimental study of the charge saturation levels of an aircraft with an active electrostatic charge control system
(2022)
Conference report
Restricted access - publisher's policyArtificially charging an aircraft might reduce the risk of triggered-lightning. In this study, we explore the charging limits of an Unmanned Aerial Vehicle charged using an artificial electrostatic charge control system ... -
Experiments with a tethered drone to investigate induced charges on a vertically arranged conductor during fair weather
(2021)
Conference report
Open AccessTo better understand the phenomena associated with electrostatic charges and potential distribution over vertical conductors, this work describes preliminary results obtained with a tethered drone that is used to lay ... -
High-energy radiation from natural lightning observed in coincidence with a VHF broadband interferometer
(2021-04-16)
Article
Open AccessThis work presents the first simultaneous X-ray measurements from natural lightning in coincidence with a very high frequency (VHF) broadband interferometer. During an observational campaign in north-central Colombia, five ... -
Influence of electrostatic charge on lightning interactions with aircraft and wind turbines: an experimental approach to an active charge control application
(Universitat Politècnica de Catalunya, 2023-11-17)
Doctoral thesis
Open Access(English) Lightning strikes to aircraft and wind turbines can lead to substantial repair expenses. These structures often trigger lightning strikes, in the form of bidirectional leaders in the case of aircraft and upward ... -
Measurement of electric potential of isolated vertical conductive wires pulled by a drone under fair weather conditions
(2018)
Conference lecture
Restricted access - publisher's policyThe popularization of multicopter drones opens new possibilities for investigations of the atmospheric potential. The method of directly measuring of the electric potential drop of the lower part of the atmosphere has been ... -
Small scale simulation of lightning using vertical wires deployed by drones: on the land and sea peak current asymetry
(2022)
Conference report
Restricted access - publisher's policyIn this work we simulate lightning by means of vertical wires deployed by a multirotor drone under fair weather conditions. These wires, when isolated from ground, acquire an electric potential by virtue of electrostatic ... -
Study of an active charge control system for aircraft : hammer system
(Universitat Politècnica de Catalunya, 2019-06-20)
Master thesis
Restricted access - author's decisionOn average, it is estimated that commercial aircraft is struck by lightning about one per year. Although nowadays lightning strikes to aircraft do not pose a major tread for the aircraft safety, the required inspections ... -
