| 为了解决飞行器高速飞行过程中精细化感知壁面静态压力分布与动态压力变化的复杂问题，通过精细配比聚二甲基硅烷?碳纳米管（Polydimethylsilane?Carbon Nanotubes， PDMS?CNTs）的材料浓度，并键合连接传感器的电极层和介电层，研制了一款基于PDMS介电材料的电容式柔性压力传感器，克服了传感器电极层和介电层界面摩擦、能量损耗失配的难点。通过静 / 动态性能验证实验，验证了传感器的静态压力分布以及动态压力变化。结果显示，所研制的传感器在检测 0.1 ~ 104.9 kPa 静态压力的同时，能够实现10 ~ 2 000 Hz振动频率条件下的动态压力检测，具有良好的静 / 动态压力感知能力。可将此柔性压力传感器应用于飞行器复杂的曲面结构，其在优化飞行器的气动外形方面具有良好的应用前景。 |
| 英文摘要: |
| In order to solve the complex problem of finely sensing the static pressure distribution and dynamic pressure changes on the wall during high?speed flight of aircraft, a capacitive flexible pressure sensor based on PDMS dielectric material was developed by finely matching the material concentration of PDMS?CNTs and bonding the electrode layer and dielectric layer of the sensor. The difficulty of interface friction and energy loss mismatch between electrode layer and dielectric layer was overcome. The static pressure distribution and dynamic pressure change of the sensor were verified by static/dynamic performance verification experiments. The results show that the developed sensor can detect the static pressure of 0.1 ~ 104.9 kPa, can realize the dynamic pressure detection under the vibration frequency of 10 ~ 2 000 Hz, and has good static/dynamic pressure sensing ability. The flexible pressure sensor can be applied to the complex curved structure of aircraft, and has a good application prospect in optimizing the aerodynamic shape of aircraft. |
