The 14th International Symposium on Sound Engineering and Tonmeistering will be held on May 19-21, 2011, in Wrocław. The Symposium is organized by the Chair of Acoustics, Institute of Telecommunications, Teleinformatics and Acoustics, Wrocław University of Technology, under auspicious of the Polish Section of the Audio Engineering Society. The organizers cordially invite sound engineers, music producers, acousticians, and specialists in sound reinforcement, scientists who deal with sound engineering, sound recording and related areas, students, and employees of the audio industry to participate in the Symposium. The Symposium programme will include lecture sessions and workshop presentations.

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. Advantages of combustion at constant volume were described as well as the basic turbo engine updates required to reflect pulse combustor application. The calculation results for analytical model of a basic engine, and that equipped with pulse combustor are included in this paper. The paper describes the required changes in the engine structure and construction and the estimated thermodynamic improvements. Axial-type pulse multi-chamber combustion unit increasing the pressure and temperature of gases requires a special additional turbine utilizing additional energy and forming the interface between the standard compressor-turbine unit. Performance calculations done for an existing GTD-350 engine showed that constant-volume combustion process is valuable.
