Abstract

A structural scheme is considered for a bench to test aircraft gas turbine engines. The characteristic feature for this test bench is slotted flat-formed ring nozzle with toroidal ring jet. The nozzle is link with embedded pipeline by means of elastic elements. This approach makes possible to eliminate intake air impulse, therefore to increase significantly characteristics measurement precision for aircraft engine tested.
