Abstract

Pesawat Amfibi (Floatplane) merupakan salah satu sarana transportasi udara yang dapat mendarat di laut dan di darat. Wahana pesawat terbang ini dirancang memiliki Floater di bagian kaki pesawat yang berfungsi mengapungkan pesawat di permukaan air. PT DI telah merencanakan pengembangan pesawat N219 amfibi sehingga membutuhkan desain Floater yang mendukung operasi pesawat, diantaranya bermanuver di perairan. Studi manuver ini sangat penting karena kemampuan manuver akan menjamin keselamatan penumpang N219 dari bahaya tabrakan dengan obyek lainnya ketika beroperasi di perairan. Studi ini bertujuan menganalisis kemampuan manuver pesawat amfibi N219 terhadap variable jarak antar floater yang bertipe katamaran, trim floater, dan kecepatan operasi. Adapun metode yang diusulkan adalah pengujian model Floatplane dengan menggunakan teknik open free running test yaitu pergerakan model Floatplane dikendalikan oleh operator di tepi kolam dengan sistem komunikasi nirkabel, dimana dalam uji manuver melingkar akan direkam titik lintasan manuver dan gerakan yaw, sway, dan roll.. Dari hasil pengujian manuver didapatkan nilai turning maneuver terbaik pada jarak antar lambung S/L 0,5 dan Fr 0,064 dengan nilai A, T, TD, dan R secara berurutan 1,60 meter; 1,61 meter; 2,50 meter dan 1,27 meter. kemudian hasil gerakan didapatkan nilai sudut roll, yaw, dan gerakan sway terbaik pada kondisi yang sama dengan nilai roll, yaw, dan sway secara berurutan 5,753 derajat; 13,236 derajat; dan 1,824 m.

The amphibious aircraft (Floatplane) is one of the air transportation means that can land on both water and land. This type of aircraft is designed with floaters on the aircraft's landing gear to enable it to float on the water's surface. PT DI has planned the development of the N219 amphibious aircraft, requiring a Floater design that supports the aircraft's operations, including maneuvering in water. This maneuver study is crucial as the aircraft's maneuvering capabilities ensure the safety of N219 passengers from collisions with other objects when operating on water. The aim of this study is to analyze the maneuvering capabilities of the N219 amphibious aircraft concerning the distance between catamaran-type floaters, trim floaters, and operating speed. The proposed method involves testing the Floatplane model using the open free-running test technique, where the model's movement is controlled by an operator at the pool's edge through wireless communication. In maneuvering tests, circular maneuver trajectory points and yaw, sway, and roll movements are recorded. From the maneuvering test results, the best turning maneuver values were obtained at a distance between hulls S/L 0.5 and Fr 0.064, with values of A, T, TD, and R being 1.60 meters, 1.61 meters, 2.50 meters, and 1.27 meters, respectively. Additionally, the motion results revealed the best roll, yaw, and sway movement angles under the same conditions, with values of 5.753 degrees, 13.236 degrees, and 1.824 meters, respectively.
