Abstract

Na zrakoplov u letu djeluju četiri sile: sila uzgona, sila potiska, težina zrakoplova i sila otpora. Sila otpora sastoji se od dvije komponente, parazitnog i induciranog otpora. Inducirani otpor nastaje kao posljedica proizvodnje uzgona, većinom na krilima zrakoplova, i predstavlja značajan udio u ukupnom otporu u određenim fazama leta. Također, uz pojavu induciranog otpora nastaju i vršni vrtlozi koji mogu biti opasni za druge zrakoplove tijekom operacija u blizini aerodroma. Prilikom dizajniranja zrakoplova i proračuna performansi bitno je znati utjecaj pojedinih dijelova zrakoplova na veličinu induciranog otpora te se koriste oni dijelovi koji u najvećoj mjeri smanjuju inducirani otpor zrakoplova, tj. poboljšavaju performanse zrakoplova.

Abstract (english)

There are four forces that act on an aircraft in flight, those are: lift, thrust, weight and drag. Drag is consisted of two components: parasitic drag and induced drag. Induced drag is a byproduct of lift production, mostly on aircraft wings, and makes a major part in total drag of an aircraft in certain part of flight. Wing tip vortices are closely related to induced drag and can be very dangerous to other aircraft which are operating in the vicinity of an aerodrome. While designing an aircraft and studying its performance, it is important to know how each part of an aircraft influences induced drag, both individually and combined with other parts, so that only the best parts can be used.
