Abstract:
The control of foreign object debris is an essential part in the design and testing of aerospace products. However, since efficiency and accuracy of current foreign object debris detecting methods are low, a STM32-based system for detecting and cleaning the foreign object debris in pipelines of liquid rocket engine was designed. It is composed of ultrasonic pipe cleaning device, foreign object debris detecting device, signal acquisition device and industrial computer. With the control function of STM32, the system can realize automatic detection and cleaning of the foreign object debris in pipeline of liquid rocket engine, real-time acquisition, transmission, display and storage of liquid level information and cleaning effect. In addition, re-cleaning procedure can be started according to the detection result. The system can be switched between automatic cleaning and manual cleaning, which can
