INLET DEVICE FOR TESTING GAS TURBINE ENGINE IN CLIMATIC TEST BENCH Russian patent published in 2012 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: inlet device for testing gas turbine engine in climatic test bench comprises inlet manifold, labyrinth seal assembly, pipeline made up of branch pipes, engine inlet branch pipe, support to secure inlet manifold to climatic test bench and supports to joint connected pipeline to dynamometric platform. Note here that inlet manifold, labyrinth seal assembly, connected pipeline and engine inlet branch pipe are sequentially interconnected by tight hinges, while one branch pipe of said labyrinth seal is secured, on inlet manifold side, on supports to climatic test bench, while another branch pipe on engine side is secured on platforms to dynamometric platform. Tight hinges are made up of a concentric gland seal. Supports level with pipeline axis are furnished with horizontal slide surface with a key whereon pipeline displace radially. Gland seal is made up of graphite-filled fluoroplastic.

EFFECT: higher reliability, reduced compressed air leaks.
