Nanostructured porous silicon impregnated by solid state oxidizer has been studied
in order to provide the mechanical impulse for jet-propulsion microsystems. The system with
jet-propulsion motion on a silicon chip has been tested for impulse measurements. The silicon
chip has been fastened on a carrying platform through an elastic spacer. The elastic spacer
promotes the combustion and prevents from explosion of porous silicon fast oxidation. It is
shown that such a microsystem gains the impulse up to 200-220 mNžs.
Keywords: combustion, explosion, mechanical pulse, microthruster, multichip structure, nanoporous silicon |
