1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

3. 2. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Sophia Fisher; Michael Åkerström; [2023]
   Keywords : Hybrid propulsion; mixed turbofan; parallel configuration; performance;

   Abstract : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. READ MORE

4. 3. Optimisation of a LOX/Ethanol rocket engine ignition

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Pierre Collard; [2022]
   Keywords : ;

   Abstract : For more than half a century, humanity has achieved the feat of extracting itself from the earth's atmosphere and sailing into space, broadening the spectrum of knowledge and curiosity. Although space market seemed mastered and stable the arrival of new private players has reorganized the sector through new technological choices. READ MORE

5. 4. Functionnal Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

   Keywords : Cryogenic propulsion; Electrical pump; Operating domain;

   Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, anorbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulationof the o-design operation of the cryogenic engine of Nyx. READ MORE

6. 5. Multibody modelling of the vibrations in an aircraft engine

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Charly Mollet; [2022]
   Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

   Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE
