PURPOSE: A tilting device for an air injecting nozzle of an engine test facility is provided to simulate a real flying environment with a simple construction and reduce the energy consumption of an actuator required for tilting. CONSTITUTION: A tilting device for an air injecting nozzle of an engine test facility comprises a pair of circular support plates(130), a pair of circular rotating plates(120), and an actuator(110). The circular support plates have an arc shape and coupled to the upper and lower walls of the opening of a chamber(A) held in a test unit(B). The circular rotating plate is installed on the outer surface of the circular support plates. The circular rotating plate is ball-socket-sealed with each circular support plate to be closed. One end of each circular rotating plate is coupled to the upper and lower parts of an air injecting nozzle(100).
