To build the engine, aircraft turbojet engines in theory were referred. As the compressor-turbine section of the model, a diesel engine turbocharger was selected and coupled with a developed combustion chamber. During the experiments, turbine inlet temperature was between 630°C and 890°C. However, temperature of the turbine outlet and exhaust nozzle temperatures were between 612 and 850°C. At low fuel pressures and at 17600 1/min, turbine inlet temperature was 870°C, combustion chamber inlet temperature was 68°C, manometric pressure was 0,39 bar and the exhaust nozzle temperature was 860°C. The oil pressure was 3,45 bar and the oil temperature was 65°C. When the fuel pressure was around 4 bar, the highest engine speed measured was 48660 1/min. At this speed, the turbine inlet temperature was 636°C, exhaust nozzle temperature was 612°C, compressor outlet temperature andpressure were 65°C and 0,47 bar respectively. Measured thrust values of the model jet engine were between 14 and 20 N UR - https://dergipark.org.tr/en/pub/politeknik/issue//367808 L1 - https://dergipark.org.tr/en/download/article-file/385485 ER -
