Shell sensor assembly for perceiving spacial airflow changes through piezoelectric cilia

Abstract

The invention discloses a shell sensor assembly for perceiving spacial airflow changes through piezoelectric cilia. A human body behavior of vestibular labyrinths that an inertial motion signal of the human body can be precisely converted into an electric signal through cilium bundles on sensory epithelia of the vestibular organs of the human body is simulated, so that the outer spacial airflow changes are perceived through the piezoelectric effect of the piezoelectric bionic cilia, namely, perception on the size and the direction of a spacial flow field during travelling of a shell can be achieved through a radial cilium bundle array structure and an axial cilium bundle array structure, the speed and the direction of the airflow in an three-dimensional space outside the shell are obtained by reasonably arranging the piezoelectric bionic cilium sensor and analyzing the electric signal generated by the piezoelectric bionic cilia, and accordingly the posture of a shell body can be calculated and tracked in real time.

Description

[0001] Technical field: [0002] The invention relates to a sensor assembly for piezoelectric cilia to sense spatial airflow changes, belonging to the field of intelligent materials. [0003] Background technique: [0004] When traditional shells move at high speed in space, the device for measuring the flight attitude of the shells is the internal gyroscope, but for smart shells, the traditional mechanical gyroscope cannot withstand large overload and excessive centrifugal acceleration, so a tiny sensing device is needed Covering the surface of the warhead to sense the change of the external space flow field and determine the movement information of the projectile, thereby replacing the traditional mechanical gyroscope. Imitate the human behavior of the vestibular labyrinth, that is, the cilia bundle on the sensory epithelium of the human vestibular organ can accurately convert the body's own inertial motion signal into an electrical signal, thereby using the piezoelectric eff...
