Hidravlični sistem helikopterja AB-206B

Švab, Aljaž (author), Majdič, Franc (mentor)

V okviru diplomske naloge je bil obravnavan hidravlični sistem, ki se nahaja v helikopterjih tipa AB-206B. Najprej je opisan razvoj helikopterjev ter pomembni napredki pri njihovem razvoju, nato je predstavljeno, zakaj večji helikopterji potrebujejo hidravlične sisteme za svoje delovanje. Predstavljen je celotni hidravlični sistem za krmiljenje glavnega rotorja ter ločen hidravlični sistem za zavoro glavnega rotorja. Opisana in predstavljena je vsaka komponenta v obeh hidravličnih sistemih in njena funkcija v celotnem sistemu. Predstavljena je hidravlična tekočina, ki se uporablja v takšnem hidravličnem sistemu helikopterja. Skladno s standardom ISO 1219 sta izdelani shemi hidravličnih sistemov obravnavanega helikopterja. Nato je bil izdelan tudi numerični model glavnega hidravličnega sistema, kjer smo simulirali njegovo delovanje.

Abstract

This thesis focuses on the hydraulic system integrated into AB-206B type helicopters. It begins with an overview of helicopter development and the key technological advancements in the field, followed by an explanation of the necessity for hydraulic systems in larger helicopters to ensure proper operation. A comprehensive presentation of the main rotor control hydraulic system is provided, along with a separate hydraulic system dedicated to the main rotor brake. Each component within both hydraulic systems is described in detail, including its specific function within the overall system. The hydraulic fluid used in such helicopter systems is also examined. In accordance with the ISO 1219 standard, schematic diagrams of the hydraulic systems in the helicopter under study were developed. Furthermore, a numerical model of the main hydraulic system was constructed to simulate its operational behavior.
