1. 1. Range impact of a high velocity aft-propeller on a subsonic aerodynamic body

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jens Teodor Mattsson; [2023]
   Keywords : propeller; transsonic; fluid dynamics; cfd;

   Abstract : This master’s thesis is aimed to examine the possible range increase of a ballistically fying body equipped with a propeller working at transonic velocities. To determine whetherthe propeller will provide an improvement in range, results from simulations are compared to corresponding cases of similar bodies fying without a propeller. READ MORE

3. 2. Flight Simulator Integration in Test Rig

   University essay from KTH/Flygdynamik

   Author : Tilda Sikström; [2021]
   Keywords : Flight Simulation; JSBSim; Iron Bird; real-time; Simulink; Flygsimulering; JSBSim; Iron Bird; realtid; Simulink;

   Abstract : Integrating hardware in simulations is useful in many applications, for example to investigate the performance of an aircraft with the non-ideal response of a physical system. This thesis aims to integrate a flight simulator, JSBSim, with an actuator test rig, FLUMES Iron Bird. READ MORE

4. 3. Design of a High Subsonic Nozzle for a Transonic Linear Cascade Operating at Near Stall Conditions

   University essay from KTH/Energiteknik

   Author : César Lucio; [2021]
   Keywords : ;

   Abstract : This thesis presents the results of computational fluid dynamics (CFD) design calculations of a subsonic nozzle operating at Mach number 0.85 in a transonic linear cascade wind tunnel. The purpose of the nozzle is to accelerate a fluid by decreasing the pressure energy and raising the kinetic one. READ MORE

5. 4. Two-dimensional roughness and Tollmien-Schlichting waves: a study on transition

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Derek Micheletto; [2020]
   Keywords : ;

   Abstract : Two-dimensional (2D) roughnesses induce premature transition to turbulence in laminar boundary layers by amplifying the disturbances in the flow and promoting the development of non-linearities. The present thesis aims at furthering our understanding of this phenomenon's underlying mechanisms and elucidating the effects of the different geometrical parameters of the roughness' cross section.

6. 5. Laboratory exercise - Compressible flow, oblique shock waves

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Matheus Svedholm; Josefine Gessl; [2020]
   Keywords : ;

   Abstract : When studying to become an engineer the education is mainly theoretical and to confirm the theory laboratory exercises are incorporated in the curriculum. Being able to visualize the phenomenons studied helps in giving the students a deeper understanding. READ MORE
