Modellering av avancerade komponenter för interceptorsimulering (Swedish)
Abstract [en]

Since the end of the last century, numerical simulations have been widely developed in all fields because they make it possible to predict the behavior of dynamic systems. In the field of missile systems, they are used to carry out preliminary studies, performance analyzes, trajectory simulation, etc. It is then possible to determine the conditions at each point of the flight envelope without having to conduct costly tests. In this master thesis, a 6 degrees-of-freedom simulation tool is developed to model a supersonic interceptor taking into account the effects of a rotating earth. Models for propulsion, aerodynamics, guidance-control-navigation systems are described. A comparison between a control by aerodynamic surfaces and by vector thrust during a vertical launch is made.

Abstract [sv]

Sedan slutet av förra seklet har numeriska simuleringar utvecklats i stor utsträckning inom alla områden eftersom de gör det möjligt att förutsäga beteendet hos dynamiska system. Inom området för missilsystem används de för att göra förstudier, prestandaanalyser, banans flygsimulering etc. Det är då möjligt att bestämma förhållandena vid varje punkt i flygkuvertet utan att behöva genomföra dyra tester. I denna magisteruppsats utvecklas ett simuleringsverktyg med 6 frihetsgrader för att modellera en supersonisk interceptor med hänsyn till effekterna av en roterande jord. Modeller för framdrivning, aerodynamik, styrsystem-navigationssystem beskrivs. En jämförelse mellan en kontroll med aerodynamiska ytor och med vektorkraft under en vertikal lansering görs.
