This invention belongs to the field of airworthiness testing for aero-engines and provides a high-speed imaging device for aero-engines that simulates birds swallowing flocks, based on a multi-splitter flexible imaging fiber bundle. This device is used to simultaneously observe the flight trajectories of multiple simulated birds between the air cannon and the engine inlet. It includes a first multi-splitter flexible imaging fiber bundle, with multiple first split ends each equipped with a first fiber optic lens aligned with the flight path of each simulated bird. A first high-speed imaging component is optically coupled to a first convergence end, simultaneously recording the dynamic images of all paths in a single frame. Each split end is positioned in the free space to the side of the flight path, without penetrating the engine casing.
