The invention is applicable to the technical field of aircraft ice prevention and removal, and provides a pulse discharge type bubble impact force generator for deicing, which comprises a bubble impact force exciter, the bubble impact force exciter comprises a flexible closed cavity and a liquid working medium, and the bubble impact force exciter further comprises an electrode discharge device, the electrode discharge device comprises two discharge electrodes and a pulse power supply, the positive discharge electrode and the negative discharge electrode are both arranged in the flexible closed cavity, the liquid working medium is arranged in the flexible closed cavity and is in direct contact with the two discharge electrodes, the positive discharge electrode and the negative discharge electrode are arranged at an interval, and the space between the two discharge electrodes is filled with the liquid working medium. According to the bubble impact force exciter, arc discharge is used for heating the liquid working medium, heating is faster, when the liquid working medium is vaporized, the speed of generating high-temperature and high-pressure bubbles is increased, generated small bubbles are obviously reduced, large bubbles generated by arc discharge can enable the flexible wall to expand outwards rapidly, and the impact force of the bubble impact force exciter is improved.
本发明适用于飞机防除冰技术领域,提供了一种用于除冰的脉冲放电式气泡冲击力发生器,包括气泡冲击力激励器,气泡冲击力激励器包括柔性密闭腔体和液体工质,所述气泡冲击力激励器,还包括电极放电装置,电极放电装置包括两个放电电极和脉冲电源,正放电电极、负放电电极均设置在所述柔性密闭腔体内,液体工质设置在柔性密闭腔体内并与两个放电电极直接接触,正放电电极与负放电电极间隔设置且两个放电电极之间充满液体工质。本发明使用电弧放电来进行液体工质加热,加热更迅速,在液体工质汽化时,产生高温高压气泡的速率加快,出现的小气泡明显减少,电弧放电产生的大气泡能使得柔性壁快速向外膨胀,提高气泡冲击力激励器的冲击力。
