Abstract

Zrakoplov Cessna 172 zbog svoje je jednostavnosti i pouzdanosti jedan od najčešće korištenih školskih i privatnih zrakoplova na tržištu. Cilj rada bio je na temelju različitih čimbenika koji utječu na potrebnu duljinu za zalet i brzinu da zrakoplov odvoji od tla napraviti proračun potrebnih duljina i brzina te su se dobivene vrijednosti usporedile sa stvarnim vrijednostima koje su prethodno izmjerene na zrakoplovu. Za dane atmosferske uvjete i ukupnu masu zrakoplova prvo je izmjerena brzina i potrebna udaljenost nakon čega su se te vrijednosti usporedile s proračunom. Zatim se dobivene vrijednosti uspoređuju s vrijednostima iz Operativnog priručnika za pilote (Pilot's Operating Handbook ) i objašnjavaju razlozi zbog kojih je došlo do odstupanja. Proračunata vrijednost brzine pri kojoj je zrakoplov odvojio od uzletno - sletne staze iznosi 62 kt, dok je ona izmjerena iznosila 56 kt. Potrebna udaljenost da odvoji iznosila je 398 m, dok je vrijednost u POH - u 283 m, a kao glavni razlozi izdvojena je nekvalitetna uzletno - sletna staza, pojednostavljen matematički model i smanjena aerodinamika C172 zbog duge eksplotacije zrakoplova.

Abstract (english)

The Cessna 172 aircraft is one of the most frequently used training and private aircrafts due to its simplicity and reliability. The objective of this work was to calculate and measure take - off distance required and lift - off speed according to different atmospheric and aircraft parameters. For the given atmospheric conditions and total aircraft mass lift off - speed was measured and those values were compared with calculated values. Both measured and calculated values were compared with Pilot's Operating Handbook and reasons why there are deviations in values were explained. Calculated lift - off speed is 62 kn, when the measured value is 56 kn. Take - off roll distance is 398 m while the calculated value from Pilot's Operating Handbook is 283 m for the given atmospheric conditions. Main reasons for deviations in the results are poor runway surface conditions, simple mathematical model and bad aerodynamics as a result of very long exploitation of C172 aircraft.
