| Abstract: | Rolls Royce plc is a designer and manufacturer of heavy-duty gas turbines for a variety of applications. Their products are used globally for military and civil aerospace applications, marine propulsion systems and energy production. My internship took place in the combustion subsystem of the civil large engines business. This department is responsible for the development and design of the combustion system for the current and future jet engines on large civil airplanes. This internship focussed on two subjects, experimental research on the combustion systems and on the data analysis and modelling. Experimental work on three different experimental setups is discussed. The first being altitude relight capabilities, the second setup determines acoustic responses of system components and the third setup investigates high pressure combustion with a laser measurement technique. All major steps involved in the setup and execution for a combustion experiment are investigated. The data analysis is performed on the newly obtained experimental results and on existing data. There is a copious amount of data available and it is challenging to derive the correct conclusions and make validate assumptions required for the development of numerical models. This is one of the challenges that is dealt with on a daily basis. The results on altitude relight and the results of the acoustic setup are promising. Geometry optimizations have been determined in the altitude relight facility and the experimental accuracy and repeatability are determined. Improved physical understanding and a large cost saving are shown with the acoustic performance investigation. |
