【摘要】 爆炸丝现象(exploding wires phenomenon)是将存储于高压电容器中的能量,在极短的瞬间内倾注于很小截面积的金属丝,使之汽化,产生强大的冲击波,这种冲击波产生的根本原因就是等离子体。等离子体推进技术在航天工业的应用很多,它作为辅助动力源,具有功耗少、安全可靠的优点。传统的水中电磁流体推进可以产生较大的推力,但它主要依赖于超导技术,对超导材料的要求严格、实现困难、效率低,在很大程度上制约了这种技术的应用。 本文在对等离子体推进、液中放电和爆炸丝现象综述的基础上,将这三个领域的技术结合在一起,研制出实验用水中脉冲等离子体推进模型。水中脉冲等离子体推进的主要特点是瞬间推力大,但由于它所产生的平均推力小,更适合用作助推力,可实现船舶的定向和准确停靠。文中阐述了该模型的基本结构、工作原理、微机控制系统及其设计方法,给出了主电路和微机控制系统的硬件电路设计及部分软件流程图。最后对模型的实验波形进行了描点分析,得到了相关的关系曲线,并且对在实验过程中出现的问题进行了探讨。
【Abstract】 Exploding wires phenomenon is that if the high-density energy is poured into metal wire with small transverse section in a short time from high power pulse source, the metal wire will explode into gaseity and generate significant shock wave. The .fundamental reason of the generated shock wave is the plasma. The plasma propulsion technology is applied abroad in spaceflight industry field as the assistant power source, which has the excellences such as little power exhausting and safe’ credibility. Traditional electromagnetic hydrodynamic propeller in water, which depends on super conduct technique, generates the stronger thrust. But the disadvantages that have strict request with super conduct material and difficult realization and low efficiency restrict the application of this technique in a large of degree.In the summarize of plasma propulsion and discharging in water and exploding wires phenomenon, this paper combines technology in three fields hereinbefore. An experimental pulse plasma propeller model has been designed. The main characteristic of pulse plasma propulsion in water is great propulsion in moment, whose average propulsion is smaller. So it may be useful for side face propulsion of ships in static state as the assistant propulsion. The paper firstly expatiates the basic configuration, work theory, MCU control system and design method of the model. And then it introduces the hardware circuit design of the main circuit and MCU control system and a part of software flow chart. Finally it gives some correlative graphs of experimental data by analysis of experimental wave and discusses the arisen problem in experiment course.
