Abstract

V nalogi obravnavamo, kakšni poteki obremenitev se pojavljajo pri različnih vrstah režimov letenja (vzletanje, vzpenjanje, vodoraven let, spuščanje in pristajanje). Najpomembnejši dejavnik pri obremenitvah letala so aerodinamične sile, ki so predstavljene skupaj z vsemi dejavniki, ki vplivajo nanje. Za ugotovitev poteka obremenitev smo opravili meritve pospeška s pomočjo pospeškomera LSM6DSO. Meritve smo vzorčili na letalu Cessna 172, ki je letelo standardne šolske kroge. Nato so bili ti podatki preneseni v program, ki je bil razvit za obdelavo teh podatkov s števno metodo prehodov prek nivojev. Metoda izloči obremenitvene cikle, ki ne vplivajo na obremenitev letala. Ugotovili smo, da se največje obremenitve, pojavijo pri pristanku, drugi režimi prikazujejo manjši, a med seboj precej podoben potek obremenitev.

Secondary title: Load spectra at typical flight regimes of airplane Cessna 172
Secondary abstract: In this thesis, we examine what loads appear with different types of flight regimes (take-off, climb, cruise, descent and landing). The aerodynamic forces, which are presented along with any factors that may affect them, represent the most important factor in aircraft loads. To determine the aircraft’s load, we performed acceleration measurements by using the LSM6DSO. The measurements were sampled on the Cessna 172 airplane, which was flying standard training laps. This data was transferred to the software developed for processing the data by using the level crossing cycle counting method. This method eliminates loading cycles that do not affect aircraft loading. Our research confirmed that the highest loads occur at landing, while the other regimes show a smaller, but rather similar load pattern.
