Analisis Performa Micro Turbojet Engine Aero-16 Berbasis Turbocharge Holset

Jurnal Mahasiswa Dirgantara, 2023
Pesawat terbang adalah kendaraan yang mampu terbang di udara. Pesawat  dapat terbang karena memiliki 4 gaya yaitu thrust, drag, weight dan lift. 4 gaya tersebut dapat berkerja di pesawat karena ada bantuan dari engine dan wing. Engine yang terdapat pada pesawat terbang digunakan untuk mendapatkan thrust.
