Abstract

Ionska propulzija, iako cˇesto povezana sa svemirom, takod¯er pruža znacˇajne moguc´nosti
za poboljšanje performansi letjelica u atmosferskim uvjetima. Jedna od kljuˇcnih komponenti
ovog tehnološkog pristupa je koronalni izboj, koji igra centralnu ulogu u stvaranju potiska
bez pokretnih dijelova. Uz to, korištenje kombinacije potisnika na postavu koji predstavlja
letjelicu dodatno otvara puteve za upravljanje valjanja letjelice, što je bitno za njenu stabilnost
i kontrolu.
U ovom je radu izveden postav koji omogu´cuje Postupak izraˇcuna parametra ionskog propulzora
te na temelju toga omogu´cuje upravljanje zakreta postava. Pokazano je kako ionska
propulzija stvara dovoljno potiska za stvaranje kuta zakreta postava kao i upravljanja kuta
zakreta istog.
Na temelju podataka odziva i provedene identifikacije bilo je mogu´ce odrediti potisak koji
se razvija na postavu i kao takav upravlja postavom. Takod¯er u radu je uspored¯en stvarni i
simulirani odziv kao validacija podataka.
Na temelju danog postava i modela letjelice simulirano je vladanje valjanja letjelice pod
utjecajem potisnika na krilima i pokazano je kako sila razvijena u ovom radu nije dostatna
za upravljanje kutem valjanja ve´c je dovoljna iskljuˇcivo za ustabiljavanje sustava koji je ve´c
dovoljno blizu stabilnom letu u odnosu na kut valjanja.

Abstract (english)

Ion propulsion, although often associated with space, also offers significant opportunities
to improve the performance of aircraft under atmospheric conditions. One of the key components
of this technological approach is the corona discharge, which plays a central role in
generating thrust without moving parts. Additionally, the use of a combination of thrusters
on the aircraft configuration further opens pathways for roll control of the aircraft, which is
essential for its stability and control.
In this paper, a setup is presented that enables the calculation process of ion thruster
parameters and, based on that, allows for roll control of the setup. It is demonstrated how
ion propulsion generates sufficient thrust to create and control the roll angle of the setup.
Based on the response data and conducted identification, it was possible to determine the
thrust developed on the setup, which in turn controls the setup. The paper also compares the
actual and simulated responses as a validation of the data.
Using the given setup and aircraft model, the behavior of aircraft rolling under the influence
of wing-mounted thrusters was simulated, and it was shown that the force developed
in this study is not sufficient for roll angle control but is adequate solely for stabilizing the
system that is already close to stable flight with respect to the roll angle.
