摘　　要：引信用气流谐振发电机(射流发电机)基于亥姆霍兹共鸣器,利用弹丸在弹道飞行过程中的气动能发电,其换能器为磁电发电机,由于体积大、重量大,限制了其使用范围。为了改善这种状况,提出了气流谐振压电发电机,以压电薄膜代替其磁电发电机。通过实验室模拟吹风试验证明:该发电机输出功率较大,可满足低功耗引信的使用,且结构简单、体积小、成本低、重量轻,不会产生交变磁场。The air driven fluidic resonance generator（the fluidic generator） for fuzes,which is based on Helmholtz resonator generates power by aerodynamic of the projectile in ballistic flight.Its magnetoelectric transducer is limited in application scope due to its big volume and heavy weight.In order to make an improvement of this,an air-driven fluidic resonance piezoelectric generator is put forward,which use piezoelectric film instead of magnetoelectric transducer.The wind tunnel test proves that the given generator which is of simple structure,small volume and low cost provides enough output power for low power fuzes without alternating magnetic field.
