## 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.

## Claims

### Claim 1

A jet propulsor using gas or liquid of the environment the propulsor is in as an operating medium, the propulsor comprising eight nozzles, a plurality of channels interconnecting the nozzles, and pressure units arranged in the channels for controlling a magnitude and a direction of a head in a flow of the operating medium in the channel, each of the nozzles is adapted to control a direction of a discharge of a jet of the operating medium and to provide an intake of the operating medium from the environment into the propulsor, as well as the discharge of the operating medium from the propulsor into the environment, characterized in that the plurality of channels comprises eight active channels equipped with the pressure units, four intermediate channels, and a central channel, each of the eight active channels with the pressure units therein is connected by one end thereof to one of the nozzles, all active channels with the pressure units therein are pairwise connected to each other by other ends thereof thus forming four connecting nodes of the active channels, each one of the intermediate channels is connected by one end thereof to a respective connecting node of the active channels, the four intermediate channels are pairwise connected to each other by other ends thereof thus forming two connecting nodes of the intermediate channels, and the central channel is connected by ends thereof to the two connecting nodes of the intermediate channels.
