Razvojni potencial elektrifikacije letaliških premikov komercialnih letal

Rus, Vid (author), Grebenšek, Andrej (mentor)

V diplomski nalogi se ukvarjamo s prototipnimi sistemi za elektrifikacijo premikov letal po letaliških površinah, z namenom zmanjševanja operativnih stroškov letalskih družb in vpliva na okolje. Predstavljeni so trije vodilni sistemi in njihove prednosti ter slabosti. Drugi del je osredotočen na potencialne razvojne razširitve dotičnih sistemov z dodanim regenerativnim zaviranjem, kjer je določena približna ocena moči sistema, ki bi bila potrebna za regenerativno zaviranje pri pristanku letala. Predlagana je možnost razširitve z diferencialnim obračanjem, kjer je določena najmanjša potrebna širina letališke poti za obrat letala. Analizirana je razširitev sistema, s sinhronizacijo hitrosti koles s stezo pri pristanku, kjer je ugotovljeno, da je moment precesije pri pristajanju v bočnem vetru zanemarljive velikosti.

• Title: Development potential of commercial aircraft ground movement electrification

Abstract

This diploma thesis deals with prototype systems that focus on electrification of commercial ground movement on airfields, with the purpose of reducing operating costs of airliners and impact on environment. Three leading systems are presented with their advantages and disadvantages. The second part focuses on potential development of aforementioned systems with added capability of regenerative braking. The approximate system power that is needed for regenerative braking during aircraft landing is estimated. Possible improvements with differential turning is suggested and the minimum taxiway width for an aircraft turn is calculated. A system extension with landing gear speed synchronization is analyzed and it is concluded that gyroscopic precession during landing in crosswind has negligible effect on aircraft handling.
