ABSTRACT

The engine spindle rotation damping test device designed in this paper can detect whether the engine rotor system rotates well. As the core component of a miniature turbojet engine, the operating state of the rotor system directly affects the engine's operating state and service life. This design uses the STM32F407 microcontroller as the control core, and collects the engine speed and current value per unit time through the current sensor ACS712 and Hall speed sensor. The results show that the design can directly display the engine's rotational damping characteristics, ensure the safety of engine test run, and provide guidance for engine condition parameter binding.
