1. Menghitung nilai-nilai dimensi daun propeller Dimensi propeller meliputi ar, br, cr, dan Sr. Nilai-nilai di atas diperoleh dari tabel berikut:

2. Menghitung Ordinat YFACE dan YBACK Titik-titik koordinat yang dibutuhkan oleh profil dapat dihitung dengan formulasi yang diberikan oleh Van Gent et al (1973) dan Van Oossanen (1974) adalah sebagai berikut :

Setelah mengetahui nilai masing - masing (cr,ar,br dan Sr) diatas, maka langkah pengerjaan dilanjutkan pada penentuan penampang ketebalan tiap bagian daun menggunakan rumusan dan tabel dibawah ini :
