基于超声能量传输与数据通信的密闭金属舱环境监测系统设计与实现OA

The storage of solid rocket motors is a critical component of the national strategic system.To ensure the safety and extend the service life of solid rocket motors,a closed metallic chamber monitoring system based on ultrasonic energy transmission and data com-munication is designed,which enables real-time monitoring of environmental parameters such as temperature,humidity,and concentra-tions of NO and NO2 to assess the health status of the motors.The measurement results,combined with the consumption of stabilizers in the control group,form an advanced monitoring and diagnostic tool.This approach overcomes the limitations of traditional physical and mechanical aging monitoring methods,such as structural damage to the motor,limited testing range,and low accuracy.Additionally,the system is used to test the environmental parameters at different time intervals under high-temperature conditions(85℃)for composite modified double-base propellants.These data reveal the high-temperature aging mechanism of the propellant and also validate the relia-bility and stability of the system,providing essential datasets for the prediction of the motor's service life.
