The laboratory test rig with miniature jet engine to research aviation fuels combustion process

This article presents laboratory test rig with a miniature turbojet engine (MiniJETRig – ature et ngine est ), that was built in the Air Force Institute of Technology. The test rig has been developed for research and development works aimed at modelling and investigating processes and phenomena occurring in full scale jet engines. In the article construction of a test rig is described, with a brief discussion on the functionality of each of its main components. Additionally examples of measurement results obtained during the realization of the initial tests have been included, presenting the capabilities of the test rig.
