Momentum coupling model for laser driven flying plates

Laser-driven flying plates technique(LDFT) is an important and feasible way to load materials and simulate high-velocity motion law of space articles. The momentum coupling model for laser-driven flying plates is one of the important research fields of laser driven flyer plates techniques, whose essence is macroscopical representation of laser-material interaction law. According to lasersupporteddetonatingwave(LSDW) theory, this article builds a model on momentum calculation of laser driven flying plates under constraints. Taking into account the factors such as laser power density,pulse width, focus spot area, sparse wave, atmosphere parameters of flying plates surface and flyer plates area, the model demonstrates the action mechanism of flying plates by LSDW theory.
