Description
Technical Field
The invention relates to the technical field of propellers, in particular to a ternary vector pump jet propeller integrating double-stator driving and a power unit.
Background
The propulsion power of the early ship mainly depends on manpower and wind power, and steamships using propellers as propellers eliminate steamships provided with paddle wheels. By the 20 th century, the uk first applied water jet propulsion to a submersible. The water jet propulsion as a novel power device is widely applied in the fields of military ships, underwater vehicle propulsion and the like. Compared with the traditional power device propeller, the water jet propulsion has the advantages of higher propulsion efficiency, small vibration noise, good shallow propulsion performance, good manipulation performance, strong adaptability to variable working conditions, good cavitation resistance and the like at high navigational speed. At present, the research of various scholars at home and abroad on the pitching and yawing performance and the flowing problem of the water jet propulsion pump mainly focuses on the aspects of theoretical design and optimization of the water jet propulsion pump and the aspects of propulsion performance, internal flow characteristic and the like when the water jet propulsion pump is singly considered, but the technology for realizing the free deflection control of the jet pipe of the underwater vehicle is still immature.
In the prior art, when the underwater vehicle deflects to navigate, if the rudder blade is in the rudder position, the water acting forces on the two sides of the rudder blade are equal, so that the motion direction of the ship is not influenced. However, when the rudder blade rotates by an angle, the water flows on the two sides are not symmetrical any more, so that the side of the deflection angle of the rudder blade is called the upstream side, and the back side of the rudder blade is the backside. When water flows around the rudder blade, the flow of the back surface is longer than that of the upstream surface, the flow velocity of the back surface is higher, the static pressure on the back surface is lower than that of the upstream surface, and thus, the upstream surface and the back surface generate pressure difference to drive the underwater vehicle to deflect, but the water resistance is increased to influence the navigation speed.
The existing yaw rudder and spray pipe technology can only realize rapid yaw under the condition of keeping high navigational speed, and the pressure difference between the upstream surface and the downstream surface of the yaw rudder is small under the condition of low speed or starting state, so that the underwater vehicle cannot effectively yaw and cannot realize pitching assistance. Therefore, the novel ternary pump jet vector propeller is designed to assist or replace an underwater vehicle to yaw and a pitching rudder blade to realize pitching or yawing running under various navigation states.
