1. Implementation and comparison of the Aircraft Intent Description Language and point-mass Non-Linear Dynamic Inversion approach to aircraft modelling in Modelica
University essay from Linköpings universitet/Fluida och mekatroniska systemAbstract : The study is conducted to determine practical modelling and simulation techniques to perform dynamic stability and performance analysis on a 3 Degrees of freedom aircraft model using a Modelica-based commercial tool called Modelon Impact. This study is based on a conceptual aircraft model where in-depth details about the aircraft configuration are unknown and the aim is to determine a suitable model that can capture the longitudinal dynamics and aerodynamic constraints of the aircraft during the conceptual design phase.

2. Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle
University essay from KTH/RymdteknikAbstract : The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage.
