| Abstract:Aiming at the problems of less bird ingestion test，immature test method and non-standard in China，the differences of GJB
241A、GJB 242A、GJB 3727、CCAR33 in weight，quantity，speed，impact position，engine status and test procedure of bird ingestion test
were compared and analyzed. The selection and development methods of test equipment were proposed from the aspects of test bench，bird
throwing equipment，speed measuring device and bird shell. Combined with the bird ingestion test of a certain engine，the specific test tech?
nical indexes were determined，the special bird throwing test equipment was developed and the bird ingestion test procedures and methods
were formulated. The bird ingestion test of the engine was carried out for the first time in the engine finalization，and the satisfactory test re?
sults were obtained，which verified the feasibility and effectiveness of the determination of test technical indexes，the selection of test equip?
ment and the development method. Constructive suggestions were put forward on the effects of bird ingestion test on engine，protective mea?
sures，bird throwing equipment，emergency plan and collision location. |
