Material Analysis of Selected Parts of the MPM 20 Jet Engine
Keywords:
Small jet engine, combustion chamber, turbine blade, material engineeringAbstract
The Article deals with the issue of material analyses performed on the selected parts of the MPM – 20 jet engine, made within the framework of reverse engineering. The analyses were necessitated by the absence of appropriate technical documentation to the engine. The engine is result of conversion made on an original turbostarter TS – 20B/21. This device was formerly used for starting up of more powerful military jet engines. The material analyses were focused on the most thermally stressed parts of the engine - combustion chamber consisting of flame tube and combustion chamber casing, turbine blades and turbine outer ring. The findings are expected to be applicable for further technological modifications of the engine assumed to extend its operational time and total engine efficiency.
