Abstract
Fokus ovog rada su optimalna krila s raspodjelom opterećenja koja minimizira inducirani otpor za različita ograničenja. Ograničenja, uz uzgon, mogu biti geometrijska ili general- nija koja sagledavaju težinu strukture optimalnog letećeg krila. Na početku su definirani osnovni pojmovi potrebni za razumijevanje problema, zatim su izneseni i uspoređeni do sada poznati analitički rezultati za predmetni problem. Konačno, u proračunu je korištena numer- ička adaptacija klasične Prandtlove noseće linije za proizvoljna krila, koja je implementirana pomoću knjižnice NumPy u programskom jeziku Python. Koristeći navedenu metodu us- poređeno je krilo s eliptičnom raspodjelom opterećenja i krilo sa "zvonolikom" raspodjelom opterećenja te je validirana geometrija ravnog PrandtlD krila.
Abstract (english)
This thesis focuses on ideal wings with load distribution that minimizes induced drag for different restrictions. Restrictions, beside lift, can be geometrical, or more general that take in account structure weight of optimal flying wing. In the first part basic concepts needed for understanding the problem are introduced. After that, known analitical solutions for this problem are explained and compared. For calculation, Numerical adaptation of Prandtl’s classic lifting line theory is used and is implemented in Python using library NumPy. Using aforementioned method, wings with eliptical load distribution and with bellshaped load distribution were compared and geometry of straight PrandtlD wing was validated.
