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.
