It is a very useful tool to obtain a first approximation of the aerodynamic properties and for performing an optimization of the geometry design. The TORNADO tool is used to systematically calculate the aerodynamic characteristics of various wings with wingtip devices. The fast response of the aerodynamic models allows obtaining a set of results in a remarkably short time. Therefore, the development of an algorithm to generate wing geometries with great ease and complex shapes is of vital importance for the mentioned optimization process. The basic outline of the algorithm, the equations defining the wing geometries, and the results for unconventional wingtip devices, such as blended winglets and spiroid winglets, are presented. Finally, this algorithm allows designing a procedure to study the improvement of aerodynamic properties (lift, induced drag, and moment). Some examples are included to illustrate the capabilities of the algorithm.<\/jats:p>","DOI":"10.3390\/a16090439","type":"journal-article","created":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T21:41:12Z","timestamp":1694554872000},"page":"439","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Automation of Winglet Wings Geometry Generation for Its Application in TORNADO"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0685-3875","authenticated-orcid":false,"given":"\u00c1ngel Antonio","family":"Rodr\u00edguez-Sevillano","sequence":"first","affiliation":[{"name":"Escuela T\u00e9cnica Superior de Ingenier\u00eda Aeron\u00e1utica y del Espacio (ETSIAE), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5157-9935","authenticated-orcid":false,"given":"Rafael","family":"Bardera-Mora","sequence":"additional","affiliation":[{"name":"Instituto Nacional de T\u00e9cnica Aeroespacial (INTA), Torrej\u00f3n de Ardoz, 28850 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-4603-8143","authenticated-orcid":false,"given":"Alejandra","family":"L\u00f3pez-Cuervo-Alcaraz","sequence":"additional","affiliation":[{"name":"Escuela T\u00e9cnica Superior de Ingenier\u00eda Aeron\u00e1utica y del Espacio (ETSIAE), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5789-7794","authenticated-orcid":false,"given":"Daniel","family":"Anguita-Maz\u00f3n","sequence":"additional","affiliation":[{"name":"Airbus Defence and Space, 28906 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6049-6421","authenticated-orcid":false,"given":"Juan Carlos","family":"Mat\u00edas-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Instituto Nacional de T\u00e9cnica Aeroespacial (INTA), Torrej\u00f3n de Ardoz, 28850 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6694-3990","authenticated-orcid":false,"given":"Estela","family":"Barroso-Barderas","sequence":"additional","affiliation":[{"name":"Instituto Nacional de T\u00e9cnica Aeroespacial (INTA), Torrej\u00f3n de Ardoz, 28850 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8763-6348","authenticated-orcid":false,"given":"Jaime","family":"Fern\u00e1ndez-Ant\u00f3n","sequence":"additional","affiliation":[{"name":"Escuela T\u00e9cnica Superior de Ingenier\u00eda Aeron\u00e1utica y del Espacio (ETSIAE), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,12]]},"reference":[{"key":"ref_1","unstructured":"White, F.M.
