Improvements in the turbo-engine by replacement of conventional combustion chamber by a pulse combustion chamber [PDF]

open access: yesArchive of Mechanical Engineering, 2013
Abstract This paper comprises description of the turbo engine and evaluation of its analytical model. The analytical model was created to establish a benchmark for further evaluation of a wave rotor combustor (at constant volume). The wave rotor combustor concept was presented and discussed.
