Description
Technical field
The present invention relates to Propeller technology fields, and in particular to a kind of coaxial two-way twin screw dress based on annular generator
It sets and its implementation.
Background technique
If promoted for submarine navigation device only with single screw, the reaction force acts of water are in paddle, except generation makes
Outside the forward motive force of aircraft, the turning moment of circumferencial direction can be also generated.Therefore, the advance posture of aircraft is also difficult to protect
It holds, to influence the efficiency of promoting comprehensively of aircraft to move ahead with system.Therefore the torpedo or long-range from boat water promoted with propeller
The big polyisocyanate of thunder turns to double-propeller structure, and two propellers are located at same axis, and specially require two groups of propellers with same
Revolving speed and the rotation of torque opposite direction.Its major advantage has: rear paddle can completely or partially absorb the rotating energy of bow oar wake flow, from
And obtain higher propulsive efficiency；The motive force for keeping submarine navigation device forward is generated jointly when two propeller rotations, they are produced
The turning moment of raw circumferencial direction offsets each other, to effectively prevent the phenomenon of sidewindering of middle-size and small-size submarine navigation device, guarantees
The advance posture of aircraft, improves the operational efficiency of system.
In terms of aviation, most of with propeller aboard is all co-axial contra rotating propeller.This is because single group blade
Design can be such that aircraft yaws because of the turn-back torque that propeller rotation generates, and engineer is usually to pass through adjusting aileron
Carry out " trim " this tilting force, that is, make aircraft or so aileron pitch angle different, generates the power for overcoming overturning, finally make
Aircraft keeps horizontal.But the size of this tilting force is changed with the even variation of wind direction of flying speed, heading,
So aileron must be adjusted and then, this just increases the technical difficulty of aileron design.Using two groups of coaxial tandems of counter rotating propeller
Design can just make this two groups of propellers generate torsional moment mutually balance each other, aircraft would not by the power turned on one's side, thus
Facilitate the stability of aircraft flight.Under to paddle situation identical with conventional single-blade diameter is turned, to turning paddle optimum speed than general
Logical single-blade is much smaller, also wants small to the common single-blade of the optimum diameter ratio for turning paddle.
Electric drive twin screw device used by home and abroad mainly has three classes at present:
1. dragging two propeller counter rotatings by two independent regular alternating currents or direct current generator, this driving method is former
Manage fairly simple, but transmission system higher cost.Current such driving device is widely used in large ship propulsion system.
2. by separate unit regular alternating current or the dragging co-axial contra rotating propeller rotation of direct current generator+complexity planetary transmission system,
Its complicated gear reduction unit transmission system should realize mechanical reduction, complete to be input to two machinery from a mechanical mouth again
" the machinery fission " of mouth output, then directly drives co-axial contra rotating propeller rotation by inside and outside cardan shaft, leads to its mechanical drive department
It is point more complicated, and machinery driving efficiency is lower.
3. the permanent magnet direct current motor using special construction drives, China, Chang'an, packet header magneto researches and develops limited public affairs at present
Department produces this motor, and has applied in aircraft propulsion system under water.Electric machine structure is followed successively by " interior turn from inside to outside
Son, outer rotor, stator ", mechanical output form are the output of single-ended double-shaft concentric formula.The operation logic and Conventional permanent magnet of such motor
Direct current generator is identical, and the stator of Conventional permanent magnet direct current generator is only allowed also to rotate, and becomes outer rotor, and in the outermost of motor
Face, which increases, is not involved in electromechanical energy conversion, is served only for the outer mechanical stator of mechanical support.This is to include torpedo and remotely navigate certainly
Driving motor with the most use in middle-size and small-size co-axial contra rotating propeller submarine navigation device including submarine mine.Compared with first two situation, it is
System structure obtains certain simplification, and volume and weight is reduced to a certain extent, however with commutator, slip ring and two sets
On the one hand brushgear greatly reduces the operational reliability of motor；Another aspect motor cost is higher, the still aobvious complexity of structure,
In addition it is used purely for the outer mechanical stator of mechanical support, so that the volume of motor is still larger.
