Comparison of Facilities for Low Level Coupling Tests in UAV EMC Certification
(Institute of Electrical and Electronics Engineers, 2017-11-30) Fernández Romero, Sergio; Escot Bocanegra, David; Poyatos Martinez, David; Añón Cancela, M.; López Rodríguez, P.; Ministerio de Economía y Competitividad (MINECO); Agencia Estatal de Investigación (AEI)
The rise in the utilization of Unmanned Aerial Vehicles (UAVs) in the last years has also brought concerns in terms of Electromagnetic Compatibility (EMC) regulation of these platforms. Depending on the nature and operations of the UAVs, they are being required to go through the same processes than an aircraft EMC certification of aircraft involves a wide variety of tests. This paper deals with two aircraft low level coupling tests, namely, Low Level Direct Drive (LLDD) and Low Level Swept Fields (LLSF) and compares the results obtained in two different sites. On one hand, an Open Area Test Site (OATS) will be employed and, on the other hand, a Reverberation Chamber (RC) will be the other facility examined. The object under test will be a representative part of an UAV.

Electromagnetic characterization of planetary protection covers against biological and environmental contamination for EMC tests
(Institute of Electrical and Electronics Engineers, 2022-05-25) Jiménez Lorenzo, María; Plaza Gallardo, B.; López Sanz, Daniel; Muñoz Rebate, I.; Berrocal, A.; Añón Cancela, M. ; Poyatos Martínez, D.; Ministerio de Ciencia e Innovación (MICINN)
Qualification tests for space equipment and systems related to ECSS-E-ST-10-03C standard include, among others, electromagnetic compatibility (EMC) tests, that must be performed under planetary mission protection and cleanliness requirements, as well as integration and validation. Thus, all of them must be conducted under clean conditions. In consequence, it is necessary to use a protection cover that does not affect EMC tests, allowing the cleaning requirements to be met. This article focuses on the evaluation of the influence of these protection covers on the EMC tests and paves the way to investigate new geometries and materials that improve the final performance of covers, including selection of the material, development and manufacture of the cover and its electromagnetic characterization.

EMC test campaign on VEGA C launcher upper stage
(Institute of Electrical and Electronics Engineers, 2020-09-25) Jiménez Lorenzo, María; Ortiz Martín, Jesús; Albano, Rocco; López Sanz, Daniel; Morales Blanco, C.; Añón Cancela, M. ; Ministerio de Ciencia e Innovación (MICINN)
The purpose of this paper is to summarize the Electromagnetic Compatibility (EMC) test campaign carried out in the EMC Area of Spanish National Institute for Aerospace Technology (INTA) [1] of the fourth stage of the European VEGA-C launcher of the European Space Agency. This is a new launcher version which maiden flight is planned for 2020. It is an evolutionary development of its predecessor VEGA launcher, with larger Payload mass launch capability in Low Earth Orbit. The requirements for the EMC testing in space engineering are included in ECSS-E-ST-E-20-07C rev. 1 standard [2] but they usually must be adapted to each mission or project, as the requirements and electromagnetic environment are unique for each of them. This implies an intensive engineering analysis to develop the test specification and run the qualification EMC test campaign. The main characteristics of the radiated and conducted EMC tests carried out under INTA's responsibility are shown, focusing on the main challenges encountered and the way to sort them out. They are not only related to EMC requirements of the project, but also to the inherent difficulties in the management and handle of a large dimensions and complex system such as a launcher's upper stage.

UAVEMI project: Numerical and experimental EM immunity assessment of UAV for HIRF and lightning indirect effects
(Institute of Electrical and Electronics Engineers, 2016-07-07) García, Salvador G.; Silva, F.; Escot Bocanegra, D.; Pascual, Enrique; Pantoja, M. F.; Riu, Pere J.; Añón Cancela, M.; Álvarez, J.; Cabello, M.; Pous, M.; Fernández Romero, Sergio; Trallero Vela, R.; Poyatos Martinez, David; Nuño, L.; Instituto Nacional de Técnica Aeroespacial (INTA)
The UAVEMI project, funded by the Spanish Ministry of Economy and Competitiveness, gathers a consortium formed by several research and development institutions and one industrial partner. The main goal is to develop innovative experimental and numerical approaches for the assessment of the electromagnetic compatibility of unmanned air vehicles, under high intensity radiated fields, lightning indirect effects and non-nuclear electromagnetic pulses. This contribution describes the capabilities currently being developed under the project.

Validation procedure of low level coupling tests on real aircraft structure
(IEEE Xplore, 2012-12-31) Fernández Romero, Sergio; López Morales, Andrés; Añón Cancela, M.; Gutierrez, Guadalupe G.; European Commission (EC)
This paper describes the analysis of the experimental test results obtained during the low level swept coupling (LLSC) and low level direct drive (LLDD) tests on FALCON 7X horizontal tail plane provided by EADS-CASA. These techniques are evaluated during the aircraft high intensity radiated field (HIRF) certification process and in the scope of European Community's FP7 HIRF SE project. The analysis of low level test results shall be performed to estimate the influence of the test setup with particular regard to the in-flight coupling configuration. For this reason, finite difference time domain (FDTD) 3D computations have been used to determine the relationship between free field external radiation and skin current in different illumination angles and polarizations. Finally, after validation by comparison of the measured and computed skin current, measured bundle current are related to measured skin currents, to provide the transfer function link to the external field.
