摘要

In this study, a novel high-speed flyer launching strategy based on electric explosion and laser coupling was proposed to improve the launching ability of electro-explosively actuators and expand the dynamic high-pressure loading method. First, an electro-explosively actuated flyer launcher with a transparent glass substrate was fabricated by microelectromechanical system (MEMS) scale methods, which acted as a carrier to verify the idea of electric explosion and laser coupling. Then, a device of electric explosion combined with laser driving high-speed flyers was established to study the influence of nanosecond pulsed laser on the flyer launching ability of electro-explosively actuators. Finally, the velocity characteristics of the flyer and the plasma characteristics under coupled conditions are studied. The test results indicated that the introduction of laser had a positive effect on increasing the speed of the flyer. In addition, it was found that the acceleration history of the flyer is affected by the energy of electric explosion, laser energy, and the introduction time of laser.
