Abstract

Tema ovog diplomskog rada jest upravljanje toplinom pogonskih baterijskih paketa zrakoplova. U prvom dijelu dan je uvid u načine, prednosti i nedostatke pojedinih vrsta hlađenja i matematički model koji čini podlogu numeričkim simulacijama hlađenja baterijskog paketa. U drugom se dijelu detaljnije razmatra hlađenje zrakom pogonskog baterijskog paketa zrakoplova. Karakteristike baterijskog paketa pri tome određene su prema referentnom potpuno električnom zrakoplovu Extra 330LE i Samsungovim Li-ionskim cilindričnim ćelijama. Na temelju ranije razmatranih uvjeta i karakteristika hlađenja zrakom sastavljena je geometrija modula te je za nju provedena računalna simulacija hlađenja i analiza dobivenih rezultata.

Abstract (english)

Topic of this master thesis is the aircraft propulsion battery pack thermal management system. In the first part a short description of different kinds of battery cooling systems along with it’s advantages and disadvantages is given. Along with a short overwiev of battery cooling managment system, the first part of this paper also deals with mathematical model which is base for CFD simulation. The CFD simulation is discussed trougout the rest of the paper. In the second part of the master thesis highlight is on the air cooling of the aircraft propulsion battery pack. The properties of the aircraft battery module were estimated according to the one found in fully electric aircraft Extra 330LE and Samsung Li-ion cylindrical battery cells. Based on those properties, the reference module is designed and CFD simulation is conducted. In the end the results are given and discussed.
