   Author : Elina Arvidsson; [2022]
   Keywords : Esrange Space Centre; Flame deflector; Acoustic estimation; Liquid rocket engine; Rocket Factory Augsburg; Jet acoustics; Esrange Space Centre; Flammdeflektor; Akustisk estimering; vätskedriven raketmotor; Rocket Factory Augsburg; strömningsakustik;

   Abstract : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

   Author : FREDRIK RANOW; [2021]
   Keywords : Flame deflector; Launch pad; Estimation methods; Acoustics; Reflectivity; Diffraction; Directivity; Flamdeflektor; Uppskjutningsplattform; Uppskattningsmetoder; Akustik; Reflektivitet; Diffraktion; Direktivitet;

   Abstract : The aim of the project behind this report is to gain an understanding for the design criteria of launch pad flame deflectors used for launching rockets. This report presents an overview of the underlying phenomena, and then tackles the issue of estimating noise levels that come about during lift-off. READ MORE
