PENGARUH PENAMBAHAN WINGGRID TERHADAP KARAKTERISTIK DISTRIBUSI TEKANAN PADA AIRFOIL NACA 0012
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 inve stigated 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.
