Abstract

Stabilnost zrakoplova je tendencija zrakoplova da se nakon poremećaja vrati u ravnotežno stanje koje je imao prije poremećaja. S druge strane, potpuno suprotno od stabilnosti, svrha upravljivosti bi bila što lakša promjena ravnotežnog stanja i dovođenje zrakoplova u neravnotežna ubrzana gibanja (rađenje manevara). U ovome radu se eksperimentalnim letom pokazuje stupanj uzdužne stabilnosti kod dugoperiodičnog gibanja, a samim time i upravljivosti najpopularnijeg školskog zrakoplova na svijetu, Cessne 172. Također se i matematički, uzevši savršene teorijske uvjete u obzir, računaju elementi koji pokazuju stupanj stabilnosti Cessne kod dugoperiodičnog gibanja. Tako se dobiju i rezultati iz prakse i rezultati iz teorije koje je moguće usporediti. Iz svega navedenog se zaključi koliko je Cessna 172 za mnoge, manje bitno upravljiv, a sa druge strane puno bitnije stabilan i siguran zrakoplov.

Abstract (english)

Aircraft stability is the tendency of the aircraft to return to the equilibrium state it had before the disturbance. On the other hand, the complete opposite of stability, the purpose of maneuverability would be as easy as possible to change the equilibrium state and bring the aircraft into unbalanced accelerated movements (to perform maneuvers). In this paper, the degree of longitudinal stability in long-period motion, and at the same time the controllability of the most popular school plane in the world, the Cessna 172, is demonstrated through an experimental flight. Also mathematically, taking into account perfect theoretical conditions, the elements that show the stability of the Cessna in long-period motion are calculated. In this way, results from practice and results from theory are obtained, which can be compared. From all work is concluded how much is Cessna controllable, more important how much is it stable and safe aircraft.
