[en] The research project seeks to study the behavior of an airfoil against a turbulent flow, in this case air. Its aim is to assess the pressures on that airfoil, which it will be an spoiler type Formula Student single seater car, to check if this study brings some benefits to the application of this aerodynamic package. With the introduction of this spoiler into the single seater what we like to obtain is to get a better grip in the curves, with the resistance of the straight road being as minimal as possible to the advance of the car, since the aim is to make the circuit distance in the shortest time possible. Thus, there are two variables to consider when designing the spoiler. On the one hand, we have to improve the grip of tyres over the pavement when driving around a curve, which will allow us to drive faster and therefore in less time. On the other hand, the opposition exerted by the spoiler in the straight pavement advance that decreases its maximal speed. To summarize, the aim is to compare the horizontal and the vertical forces made by the air over the airfoil which will be introduced in the single seater and to evaluate whether it is beneficial to the car, that is to say, if by adding said profile the car moves faster with the spoiler than without it. For that reason, simulations will be made with a physical modeling software of flows and turbulences over a given spoiler design, with different types of flows in order to simulate road conditions as well as possible, and we will get the results about the air pressure that is exerted on the spoiler´s surface. After that, horizontal and vertical forces will be obtained and the data will be analyzed. Apart from the obtained results, other variables should be taken into consideration, such as the materials that will be employed to manufacture it, the manufacturing process itself, and the cost of that process and the materials that will be used.

[eu] Ikerketa proiektua helburua profil aerodinamiko baten portaera fluxu zurrunbilatsua baten aurka, kasu honetan airea, helburua da. Profil duten presioak zeintzuk diren ebaluatu nahi du. Profil auto baten aleroia izango da, Formula Student autoa, eta autoen aerodinamiko pakete honen portaera edozein hobekuntza lortzen bada egiaztatzeko. Autoan profil sartzen, lortu nahi da autoa heltze gehiago lortu biribilgunean eta aurrerapen erresistentzia zuzenean ahalik eta txikiena izaten. Helburua da zirkuituaren bidea egitea denbora ahalik eta laburrean. Beraz, aleroia diseinatzerakoan bi aldabera kontuan hartu behar ditugu, alde batetik asfaltoan bihurgune hartzerakoan neumatikoen heltzea hobetzea, honekin lortuko da biribilgunea abiadura handietan hartzea eta honela denbora gutxitan eta beste aldetik aurrerapen zuzenean aleroiak egiten duen oposizioa bere gehienezko abiadura gutxitzen. Laburpean indar horizontala eta indar bertikala airean egiten duena autoan sartuta profil aerodinamiko alderatzea da eta onuragarria den ala ez ebaluatzea da. Hau da, profila gehituz gero zirkuitua denbora gutxitan egiten den ala ez. Horretarako, simulazioak egingo dira fluxuen fisiko modelatua software batekin, eta turbulentzia aleroi diseinu jakin batean, fluxu mota desberdinarekin, beraz, pista baldintzak jarraitzeko modurik honena da, eta profilaren azaleen gainean aire fluxuak eragiten duen presioen emaitzak lortuko dira. Gero bertikal eta horizontal indar puntualak lortuko dira eta lortutako datuak aztertuko dira. Kontuan hartu behar izango dira, lortutako emaitzak, fabrikatzeko erabilitako materialak fabrikazio prozedura eta kostea, kontuan hartzen bai prozesua bai erabilitako materialak.
