The digital micro-propulsion system based on the solid propellant sequentially comprises a spray pipe layer, a combustion chamber and an ignition circuit layer from top to bottom. The ignition circuit layer, the combustion chamber layer and the spray pipe layer respectively and independently comprise a spray pipe unit, a combustion chamber unit and an ignition unit which are in a planar array form; the ignition units, the combustion chamber units and the spray pipe units on the same array point are sequentially connected in the longitudinal direction and correspond in position. Wherein the combustion chamber unit comprises a solid propellant located at the lower end, an afterburning chamber located at the upper end and a lining located between the wall body of the combustion chamber unit and the solid propellant; the top of the afterburning chamber is connected with an inlet of the nozzle unit; the ignition unit is connected with the bottom of the solid propellant. Through the design of an array structure formed by the spray pipe unit, the combustion chamber unit and the ignition unit, wide-range and high-precision adjustment in the thrust aspect can be achieved by controlling array number work.
