The invention discloses a high-pressure air interference eliminating device for a reverse thrust test. The device comprises a high-pressure pipeline, and further comprises three flexible interferenceeliminating units, wherein the high-pressure pipeline adopts a U-shaped structure; the first flexible interference eliminating unit is mounted at the front section of the U-shaped structure; the second flexible interference eliminating unit is mounted at the middle section of the U-shaped structure; and the third flexible interference eliminating unit is mounted at the rear section of the U-shapedstructure. The device has the advantages of being good in interference eliminating performance, small in size, low in cost and simple in structure, and also can be applied to a slip flow turbine motor wind tunnel test. According to the device, the interference eliminating in a six-degree-of-freedom direction can be carried out, and when high-pressure air is supplied to a turbine powered simulator(TPS) through the high-pre
