Abstract
N-2XX adalah pesawat generasi baru yang dirancang PT Dirgantara
Indonesia (Persero) dengan tujuan penerbangan jarak pendek dan
dioperasikan pada daerah dengan kondisi alam yang memiliki
tingkat kesulitan tinggi seperti landasan tak beraspal di wilayah
pegunungan dan kepulauan. Flap pada pesawat N-2XX digunakan
untuk meningkatkan fase terbang dimana pada flap terdapat
komponen Gap dan Overlap. Gap merupakan jarak antara trailing
edge airfoil utama dengan leading edge pada airfoil flap. Sedangkan
Overlap adalah jarak horizontal antara leading edge flap dengan
trailing edge airfoil utama. Pada airfoil LS1-0417 menggunakan
sudut defleksi pada flap sebesar 10 derajat ketika take-off dan 40
derajat ketika landing. Perubahan dilakukan dengan memperlebar
jarak Gap dan Overlap. Jarak yang digunakan menggunakan
koordinat sumbu putar Xc dan Yc, dimana Xc dan Yc nantinya akan
merepresentasikan besarnya nilai Gap dan Overlap. Pada
konfigurasi flap model VI didapatkan nilai CL sebesar 1.9324 dan
model VII sebesar 1.9422 dan model VIII sebesar 1.9399. Dengan
ini terlihat pada DF 10° model VII mendapatkan nilai CL tertinggi.
Pada DF 40° konfigurasi terbaik terdapat pada model VI yang
memiliki koordinat Xc 0.792 dan Yc -0.190 atau jika dikonversikan
pada Gap dan Overlap memiliki jarak 1.99%c dan 2.61%c dari
sebelumnya yang hanya berada pada Gap 1.50%c dan Overlap
6.47%c. ========== N-2xx is a new generation aircraft designed PT Dirgantara
Indonesia (Persero) with the purpose of short-haul flights and
operated in areas with natural conditions that have a high
degree of difficulty such as unpaved runway in mountainous
areas and islands. Flap on aircraft N-2xx is used to increase
flight phase in which the flap is a component Gap and Overlap.
Gap is the distance between the main airfoil trailing edge with
the leading edge on the airfoil flap. While Overlap is the
horizontal distance between the leading edge to the trailing edge
flap main airfoil. In LS1-0417MOD airfoil using the flap
deflection angle of 10 degrees when the take-off and 40 degrees
when landing. Changes were made to widen the Gap and
Overlap. The distances using rotary axis coordinates Xc and Yc,
where Xc and Yc will represent the value Gap and Overlap. On
the flap configuration models VI obtained CL value of 1.9324
and 1.9422 for the model VII and VIII models at 1.9399. This can
be seen in DF with 10° models CL VII highest scores. At 40° DF
best configuration found on VI models that have the coordinates
Xc and Yc 0.792 and -0.190, if converted at the Gap and Overlap
has a range of 1.99%c and 2.61%c from previously located at
the 1.50%c Gap and Overlap 6.47%c.
