Análisis del desempeño aerodinámico de un ala delta a baja velocidad

Aerodynamic performance analysis of a delta wing at low speed

Resumen

En el presente trabajo se presentan los resultados de la medición experimentales de los coeficientes aerodinámicos de un ala delta, los coeficientes determinados fueron el de sustentación, arrastre y el de momento, adicionalmente se realizó una visualización del comportamiento del fluido que pasa sobre el ala mediante la utilización de humo y de un compuesto liquido de aceite sobre la superficie del ala. Los resultados obtenidos son comparables con modelo teórico de Polhamus y con experimentales presentados en la literatura.

Palabras clave: ala delta, desempeño aerodinámico, visualización de flujo
