A new planar structure of solid propellant micro-rocket for micro-spacecraft and Micro-Air-Vehicle applications is reported in this paper. The authors have successfully fabricated an array of micro-rockets using MEMS technology. For a low-power consumption, the micro-igniter used here is a resistor deposited on a low tensile stress thin membrane to ensure a good heat transfer to the propellant. Experimental tests of ignition and microcombustion employing Double-Base (DB) solid propellant mixed with Black-Powder (BP) are reported and discussed. Tests have showed successful and continuum combustion of about 1.3 mm diameter during few 100 ms from BP ratio in the mixture (x) of 10 %. Thrust force delivered by considered structure dimensions, is ranging from 0.1 mN to 1 mN for x = 10 %, 20 % and 30 %. They expect that this planar structure will deliver a suitable thrust force of few 10 mN when reducing micro-nozzle throat dimensions.
