FIELD: transport.SUBSTANCE: reverse steering device for water-jet propulsor includes two vertical synchronous rudders secured behind nozzle and reverse choker rotary hinged on horizontal axis behind nozzle. The reverse choke is made with vertical side walls and back wall in the form of cylindrical surface equidistant relative to aftermost edges of rudders made along segment of a circle. In the upper part of reverse choker back wall steering lock is installed. In the aftermost part of side walls windows are made which windows are provided with external fitting pipes with guiding plates. On the exit section of reverse choke a baffle plate is installed which baffle is mounted using flat pillars.EFFECT: design simplification and formation of optimum directions of water flow going out of reverse choke when vessel is reversing or turning.2 cl, 7 dwg |
