Abstract
Svojim oblikom krila utječu na aerodinamičke performanse zrakoplova, na njegovu čvrstoću, težinu i inducirani otpor. Zbog izbora nepovoljnog oblika krila postoji mogućnost da će zrakoplov imati lošije performanse. Glavni oblici krila su pravokutno, eliptično, trapezno, strjelasto i delta krilo. Pravokutno krilo je najjednostavnije i koristi ga za male brzine leta. Eliptično krilo se smatra najpovoljnijim jer stvara minimalan inducirani otpor, ali je vrlo komplicirano u izradi. Kod velikih komercijalnih zrakoplova većinom se koristi strjelasto krilo koje može biti sa strijelom unaprijed ili unatrag. Delta krilo je krilo u obliku trokuta koje je nepovoljno pri malim brzinama. Veliku važnost imaju i uređaji za povećanje uzgona kako bi postigli što veću brzinu i što više skratili potrebnu duljinu staze za polijetanje i slijetanje. Uređaji za povećanje uzgona su krilca, predkrilca, zakrilca i aerodinamičke kočnice. Kako bi postigli što bolje performanse zrakoplova potrebno je posebnu pažnju posvetiti razvoju novih tehnoloških rješenja konstrukcije krila zrakoplova.
Abstract (english)
SUMMARY Wing shape has a major influence on aerodynamic performances of an aircraft, his weight and induced drag. Beacuse of a wrong choice of the wing shape aircraft can have bad aerodynamic characteristics. Main types of wing shape are rectangular, elliptical, tapered, swept and delta wing. Rectangular wing shape is the most simple and we use it on low speed aircrafts. Ideal wing shape would be elliptical because it has minimum induced drag, but it is very complicated and expensive to produce. Swept wing is used on big commercial aircrafts and it can have the angle either backward or forward from its root. Delta wing is a wing shaped in form of a triangle and it has high drag on a low altitude. Very important are mechanisms used to increase the lift in order to increase the speed and shorten the minimum length of the runway necessary for take of and landing. These mechanisms are ailerons, slats, flaps and spoilers. In order to acheive better aircraft characteristics it is very important to develop new technical solutions of the wing construction.
