Intelligent Positioning Polarity Testing of Space Engine Based on Joint Communication, Sensing and Computing

As the frequency of spacecraft launches increases and the number of aerospace engine assemblies grows, the demand for engine assembly polarity testing has surged. However, conventional manual operations are inefficient, susceptible to errors, and lack data traceability. Furthermore, there is a risk of polarity inconsistency. To ensure the precision of engine polarity during assembly, an intelligent polarity tester system has been developed through the integration of communication, sensing, and computing technologies. Key technologies, including the synchronous acquisition of loop current, electromagnetic valve magnetic field strength, and small air pressure at the nozzle, are employed to achieve a consistent interpretation of sensor fusion data. The implementation of this intelligent space engine polarity testing system enhances engine safety, optimizes performance, reduces maintenance costs, and promotes design improvements, thereby providing robust support for high-frequency spacecraft launches.
