Kanat elemanı momentum tekniği, bir pervanenin performans tayininde son derece hızlı, basit ve efektif bir yöntemdir. Geleneksel lineer kanat elemanı momentum yöntemi, direncin indüklenmiş hücum açısı üzerindeki etkisinin küçük olduğunu kabul eder. Dolayısıyla, kanat açıklığı boyunca indüklenmiş hücum açıları küçük kalır. Ancak bu yaklaşımözellikle, yüksek ilerleme sayılarında doğru sonuçlar vermez. Lineer olmayan kanat elemanı momentum teoris bu problem çözer. Bu çalışmada, DTMB 4381 test pervanesinin açık su performansı kanat elemanı momentum teorisi ve RANS yöntemleriyle incelenmiştir. Elde edilen sonuçlar, lineer kanat elemanları yönteminin sonuçları ve deneysel verilerle karşılaştırılmıştır.
