Pengaruh Penambahan Winggrid Terhadap Karakteristik Distribusi Tekanan Pada Airfoil Naca 0012

Syamsul Hadi, D Danardono Dwi Prija T


Abstrct : The research was held to investigate the effect of winggrid addition to pressure distribution characteristic on wing tip region. This research was conducted in wind tunnel at velocity 5, 10, and 15 m/s. NACA 0012 airfoil was tested to investigated the local pressure by used manometer. The pressure coefficient is used to show the impact of winggrid on the wing the pressure distribution. The result indicated that the wing tip vortex caused a reduction in pressure on the upper surface of the wing near the wing tip. Separation bubble did not formed on the near wing tip region, it’s was found distant from wing tip. Winggrid addition caused the separation disappeared from the pressure coefficient plot and increased in lift was found at contour of pressure.
