Abstract
Pesawat N-2XX adalah pesawat yang dirancang oleh PT. Dirgantara Indonesia untuk penerbangan rute perintis dan dibuat dengan teknologi full mechanical dalam melakukan penerbangannya. Pengendalian rudder yang dilakukan oleh pilot tersebut akan menghasilkan sebuah gaya ¬counter yang disebut dengan coefficient hinge moment. Nilai coefficient hinge moment dari rudder tergantung dari bentuk rudder yang dimiliki pesawat, sehingga dilakukan analisa mengenai variasi nilai hinge moment terhadap bentuk rudder yang berbeda. Penggunaan rudder dengan bentuk conic dengan defleksi 0° dan 10° memiliki nilai coefficient hinge moment yang lebih kecil dibanding rudder circle. Namun pada sudut defleksi 25° rudder conic memiliki nilai Ch sebesar 0.051166 pada angle of attack -5°, lalu sebesar 0.060217 pada angle of attack 0°, dan sebesar 0.069274 untuk angle of attack 5°.

Indonesian Aerospace Company ( PT. Dirgantara Indonesia) is developing new generation of aircraft, prototype N-2XX to solve the problem of transportation between islands. N-2XX aircraft use full mechanical technology for flying, thus the pilot will control the aircraft without electronic steering assist. Rudder is used to make the aircraft perform yawing, then the pilot just steering the rudder to do so. Controlling the rudder will results a counter measure. The counter measure is called hinge moment coefficient. The value of hinge moment coefficient depends on the shape of the rudder, thus analysist of hinge moment in different shape of rudder should be conducted. The use of conic shaped rudder in 0° and 10° deflection angles has smaller hinge moment coefficient than circle shaped rudder. Only for 25° deflection angles conic shaped rudder has more Ch which is 0.051166 for angle of attack -5°, then 0.060217 for angle of attack 0°, and 0.069274 for angle of attack 5°.
