发明背景众所周知,在先前技术中将气动电源如射流交流发电机用于弹丸引信(参阅美国专利,3568704、3772541和3971347)。这种装置安装在弹丸和导弹引信蛋形部时,冲压空气通过进气孔进入喷嘴。喷嘴包括喷嘴中心体,使冲压空气进入谐振腔,进入谐振腔的空气可产生振动。声振动可使装于谐振腔的振动膜产生振荡,振动膜依次驱动永久磁场内的金属簧片。这样感应线圈会产生感应电流,用来给引信电子组件供电。
BACKGROUND OF THE INVENTION It is well-known in the prior art to use pneumatic power sources such as jet alternators for projectile fuels (see U.S. Patent Nos. 3,568,704, 3,777,241 and 3,971,347). This device is installed in the projectile and missile fuze egg-shaped portion, the ram air into the nozzle through the air inlet. The nozzle includes a nozzle body that allows the ram air to enter the resonator and the air entering the resonator vibrates. Acoustic vibration can vibrate the diaphragm installed in the resonator, and the diaphragm sequentially drives the metal reeds in the permanent magnetic field. This induction coil will produce induced current, used to power the fuze electronic components.
