|発明の名称||PUMP JET PROPELLER WITH THRUST CONTROL DEVICE|
PROBLEM TO BE SOLVED: To provide a pump jet propeller with thrust control device which is made possible to deny the unbalanced torque generated by the rotation of a propeller, by the fluid force of a jet stream operating to a flap, as well as can run an underwater sailing body along a specific course by controlling the direction of the jet stream from the propeller, by operating the flap provided at the rear side of the propeller.
SOLUTION: A pump jet propeller 32 with a thrust control device consists of a shroud 24 which provides an interval between the rear end outer hull 2 of an underwater sailing body 20, is provided in the coaxial condition with the outer hull 2, and surrounds the outer periphery of a propeller 8; and a flap 30 which is steered by a driving device 27 supported by a vane 28 projecting from rear end inner peripheral surface of the shroud 24 to the inner side, and generates a torque in the reverse direction to deny an unbalanced torque by the rotation of the propeller 8, by the fluid force of a jet stream, as well as controls the sailing direction of the underwater sailing body 20 by converting the direction of the jet stream from the propeller 8.
