Description
Technical field
The utility model relates to a kind of small-sized oil-filled full-scale deflection vector propeller, belongs to field of ocean engineering.It is by changing the angle between propeller axis and the submarine navigation device axis, drives cruise the control with attitude of submarine navigation device in water thereby produce thrust on the assigned direction.
Background technology
Propulsion system is the chief component of submarine navigation device, and it is dimerous by engine installation and propelling unit.Propelling unit mainly contains: common screw propeller, shrouded propeller, counter rotating propeller and waterjet propulsor etc.Shrouded propeller is to add that in the screw propeller periphery elevation profile is the ring-shaped sleeve of airfoil type or the broken line shape that is similar to wing profile, and sleeve pipe can cause a flow field that helps screw propeller work, and the while is as the part of thruster.It has the efficient height, and thrust is big, can protect screw propeller to be broken by foreign object, in modern submarine navigation device uses more and more widely, but problem such as strong noise when also having high-speed operation and wake flow be serious.Counter rotating propeller is meant a pair of same axle mounting, with constant speed or the counter-rotational screw propeller of variable speed.It has simple in structure, and unbalance moment is little, and efficient still also exists cavity poor, shortcomings such as noise height than advantages such as height.Waterjet propulsor is a kind of special propulsion mode, and thrust obtains by the antagonistic force of propulsion pump ejection current, changes the manipulation that jet direction realizes sail body by devices such as control vanes.It has, and the cavity ability is strong, and appendage drag is little, and protectiveness is good, low noise advantages, but the theoretical investigation and the designing and manufacturing level of waterjet propulsor are lower at present, have limited its development.
Thrust Vectoring Technology claims the thrust deflexion technology again, the propulsion system that is meant space motion object is except can providing working direction thrust, can also simultaneously or on the directions such as pitching, driftage, roll and reaction thrust of mobile, provide propulsive force and moment separately, the power that produces in order to part or all of replacement rudder face carries out attitude control, i.e. propeller thrust vector quantization.Thrust Vectoring Technology is mainly used in the control heading of flying body and attitude angle at present improving cornering rate, thereby improves its manoevreability, agility, and under high-altitude and low-tach flying condition, higher cornering rate is arranged.
