Abstract: The invention is a jet propulsor using gas or liquid of the environment as an operating medium (OM). The propulsor comprises eight nozzles arranged centrally symmetrically and a channel system (CS). The CS comprises eight active channels (AC) with pressure units therein to control a flow head of the OM, four intermediate channels (IC) and a central channel (CC). Each of the AC is connected by one end to one of the nozzles. All AC are pairwise connected to each other by other ends, forming four connecting nodes of the AC (ACCN). Connected to each of the ACCN by one end is one of the IC pairwise interconnected by other ends and forming two connecting nodes of the IC (ICCN). The CC is connected to the ICCN. The technical result is the reduction of unproductive energy loss in the flows of the OM in the CS and increasing its efficacy.
