Available in PDF, EPUB and Kindle. Book excerpt: This work concerns the conception, the realization and the characterization of solid propellant microthruster array integrated on silicon. These MEMS devices are devoted the stabilization of small drone and also be used as propulsion module for Micro/Nano-Satellites. This study was made within a national project financed by the French Military Agency (Direction Générale pour l'Armement 'DGA') in partnership between the LAAS-CNRS and the PROTAC of THALES group. The concept is based on the high rate combustion of solid propellant or explosive stored in a micromachined chamber. The ignition process is insured by heating effect of a polysilicon resistor micromachined on thin membrane. The generated gases are accelerated throw the micro-nozzle and supply the thrust force. In a first step, we estimated the propulsion forces needed for stabilize the small drone in flight. he solid propellant micropropulsion mode is chosen because it is not complicated technology, need low power supply and generate a large rang of trust. For a specified energetic material, the generated force is adjustable from few 100μN to N simply by modifying the nozzle throat dimension. In this manuscript, we present first of all, the DGA specifications used for conception, the technology of manufacturing and assembly developed at LAAS. Finally, the thrust characterization results are given.
