The embodiment of the invention discloses an air suction type jet propulsion device suitable for an ultra-low orbit satellite. The air suction type jet propulsion device comprises an external air suction structure, a jet propulsion structure and a gas selective separation and supply structure arranged between the external air suction structure and the jet propulsion structure in a communicating mode. Wherein one or more air supply channels are formed in the jet-propelled structure; and the gas selective separation and supply structure is used for selectively supplying the gas into the corresponding gas supply channels after separating the gas sucked by the external gas suction structure into one or more groups according to components. According to the invention, gas is collected and separated in a targeted manner in an ultra-low orbit operation environment, and then is recombined for use, so that the damage to equipment and parts is avoided, and the utilization efficiency can be effectively improved and the use cost can be effectively reduced on the premise of effectively realizing the utilization of the surrounding environment.
