               Abstract:  To address the accidental explosion risks caused by sensitive primary explosives in industrial electronic detonators,
               as well as the safety and environmental issues associated with traditional no-primary detonators, a new intelligent flyer-type
               electronic  detonator  design  was  proposed  to  enhance  the  safety  and  environmental  performance  through  flyer  initiation
               technology.  To  achieve  reliable  initiation  without  sensitive  primary  explosives,  a  multi-dimensional  approach  combining
               experimental  and  numerical  simulation  methods  is  employed  for  the  design  and  performance  optimization  of  the  new
               intelligent flyer-type electronic detonator. First, critical parameters for slapper initiation were determined through theoretical
               modeling  of  shock  wave  propagation  and  energy  transfer.  A  finite  element  model  of  the  flyer  acceleration  process  was
               established  to  simulate  the  effects  of  different  charge  structures  (e.g.,  confinement  diameter,  thickness)  on  flyer  velocity,
               comprehensively considering material deformation, detonation wave interactions, and flyer fragmentation effects. Second, a
               high-speed camera (500 kHz) was used to synchronously record the detonation process, capturing the actual velocity, flight
               attitude, and deformation behavior of the flyer upon target impact. This data was used to validate the numerical model and
               optimize the structural design of the flyer generator. Third, the axial initiation capability was evaluated through standardized
               lead plate (5 mm thickness) penetration tests. The penetration depth and crater morphology were comparatively analyzed to
