Abstract

Zaleđivanje zrakoplova je pojava koja se javlja tijekom cijele godine na zemlji i u letu. Zaleđivanje negativno utječe na letne značajke zrakoplova. Kako bi se to spriječilo zračni prijevoznici, zračne luke i konstruktori zrakoplova razvili su sustave za zaštitu od zaleđivanja i sustave za sprječavanje zaleđivanja. Zaštita od zaleđivanja se postiže različitim metodama, a jedna od metoda je upotreba tekućina za odleđivanje i zaštitu od zaleđivanja. Ako se led već stvorio jedna od učinkovitih metoda uklanjanja leda je upotrebom vrućeg zraka, dok se inovativna i ekološki prihvatljiva metoda odleđivanja temelji na korištenju infracrvenih hangara. Kako bi se osigurale čiste površine za manevriranje, te održala sigurnost zrakoplova prilikom polijetanja i slijetanja moguće ih je očistiti mehanički, kemijskim tekućinama ili pomoću toplinske energije. Zaleđivanje zrakoplovna također ima negativan utjecaj na sve vrste motora, stoga je potrebno zaštiti svaki motor od utjecaja zaleđivanja.

Abstract (english)

Aircraft icing is a phenomenon that occurs throughout the year, both on the ground and during flight. Icing adversely affects the flight characteristics of aircrafts. To prevent this, airlines, airports, and aircraft manufacturers have developed anti-icing and de-icing systems. Protection against icing is achieved through various methods, and one of them involves the use of deicing/anti-icing fluid. If ice has already formed, one of effective method to remove it is by using hot air, while an innovative and environmentally friendly de-icing method involves the use of infrared hangars. To ensure clean maneuvering surfaces and maintain safety during take-off and landing, they can be cleaned mechanically, with chemical fluids, or using thermal energy. Aircraft icing also has a negative impact on all types of aircraft engines, making it necessary to protect each engine from the effects of icing.
