A dynamic distortion device

Abstract

This utility model relates to the field of intake pressure distortion testing technology, and provides a dynamic distortion device, including a duct simulation component and a plate assembly. The duct simulation component has a circular duct at its center, and the plate assembly has several plates arranged along the circumference of the circular duct. The plate assembly includes adjustable plates and a driving element. The adjustable plates are slidably connected to the duct simulation component, and the driving element is fixedly connected to the duct simulation component. The driving element is used to drive the adjustable plates to move radially closer to or away from the center of the circular duct. With this utility model, each adjustable plate can move together at the same speed or different speeds, allowing for more sets of motion curves to be obtained during testing, thereby better simulating the engine inlet airflow and dynamic distortion.
