ANALISIS PENGARUH LEBAR GAP DAN PANJANG FLAP TERHADAP AERODYNAMIC PERFORMANCE PADA MODIFIKASI AIRFOIL NREL S809 MENGGUNAKAN ANSYS

---

The are several ways to increase the aerodynamic performance of an airfoil, one of
which is adding a section behind the airfoil which commonly called a flap. Flap functions to
control aerodynamic performance. The addition of a flap to an airfoil will create a gap beteen
the airfoil body and the flap, it will certainly afferct aerodynamic performance.The gap
between the flap and the body connects the upper surface and lower surface flow field, which
can increase pressure on the upper surface.
The object is to analyze the effect of slap length and gap width on aerodynamic
performance on modiefied NREL s809 airfoil using ANSYS. The study was carried out with
variations in the length of the flaps 15%C, 25%C, 35%C with variations in the width of the
gaps 1 mm, 2 mm, and 3 mm, with flap deflections -5
o
,5,10,15o and 20oat an angle of attck

,5o
,10o
,13o
,15o and 20o
.
The result showed that the width of the gap affects aerodynamic performance, where
for each flap deflections (5o
,10o
,15o and 20o
), a 3 mm gap always has the higest drag value.
At δ=5 at AoA 20o
is 0.0070516, δ 10 o =0.081699, δ 15o =0.26014, and at δ 20 o =0.11305.
Meanwhile, the optimal length of the flap is at 15%C on the deflection of the flap (5 o
,10 o
,15
o
,20 o
) with δ 5 o =23.3617486, δ 10o =23.3617486, δ 15o =21.9860693, and δ 20o =19.1563028.
While at deflection -5
o
the length of the 15%C flap has the optimalest CL/CD ratio to increasing
the drag
