Fig. 3-6 are referred in the lump incorporated by reference to Fig. 2, for power set 3, are at least moved including the first power source 32, second
Power source 33 and trigger 34.Wherein, first power source 32 is provided with first axle 321, described first group of m/2 rotor group
It is flexibly connected with the first axle 321 respectively.Second power source 32 is provided with the second axle 331, and described second group of m/2 is individual
Rotor group is flexibly connected respectively with second axle 331.The trigger 34 respectively with the first axle 321 and second axle
331 are flexibly connected, to start the first axle 321 by the trigger 34 and second axle 331 rotates.Need explanation
It is that the first axle 321 set by first power source 32 be used to drive described first group of m/2 rotor group to be revolved
Turn, the second axle 331 set by second power source 33 be used to drive described second group of m/2 rotor group to be revolved
Turn.
Specifically, trigger 34 starts first the axle 331 of first axle 321 and second and is rotated as activation member, and
Start the postrotational first axle 321, compress the comburant injected in first power source 32, explode and burn,
Mechanical kinetic energy is converted heat into, drives the first axle 321 to continue to rotate under the impact of the air pressure of rapid expansion, Jin Ertong
Crossing the first axle 321 drives each rotor in described first group of m/2 rotor group to be rotated, and with this first is entered
The normal circulation driver of power source 32, first axle 321 and first group of m/2 rotor group.Start postrotational described
Two axles 331, compress the comburant injected in second power source 32, explode and burn, and convert heat into machinery dynamic
Can, drive second axle 331 to continue to rotate under the impact of the air pressure of rapid expansion；And then by the band of the second axle 331
Each rotor in m/2 dynamic described second group rotor group is rotated, and with this second power source 33, the second axle are entered
331 and the normal circulation driver of second group of m/2 rotor group.It should be noted that in this utility model embodiment
Trigger 34 starts after the axle 331 of first axle 321 and second rotated as activation member, then trigger 34 is automatically and first axle
321 and second axle 331 depart from and quit work, now by the first power source 32, the inside of the second power source 33 energy of itself
Conversion heat energy-mechanical energy, thinks the powered rotation of the axle 331 of first axle 321 and second.
Wherein, rotate for how trigger 34 starts the axle 331 of first axle 321 and second, this utility model is implemented
Example is not limited, and can directly trigger 34 and the axle 331 of first axle 321 and second be set up into machine driving relation, such as exists
Open up several teeth on the side wall of the axle 331 of first axle 321 and second, the rotary shaft of trigger 34 directly with first axle 321 and
Several teeth are opened up on the side wall of two axles 331 to be meshed, then by the rotation of the rotary shaft of trigger 34, drive described the
One axle 321 and the second axle 331 are rotated.For another example one can each be arranged on the side wall of the axle 331 of first axle 321 and second respectively
The individual mechanical arm that can be rotated rotating around the carrying out of the axle 331 of first axle 321 or second, 2 mechanical arms respectively with the trigger
34 connections, to drive 2 mechanical arm actions respectively by the trigger 34, realize 2 mechanical arms each then
It is corresponding to drive the axle 331 of first axle 321 or second being attached thereto to be rotated.
Again or, the first shaft gear 322 directly can be set up in the first power source 32, is set up in the second power source 33
Two shaft gears 332, set up starter receiver 31 in power set.Wherein, first shaft gear 322 is set in the first axle

One shaft gear 322 and second shaft gear 332 are meshed, to ensure the first shaft gear during starter receiver 31 is rotated
322 and second shaft gear 332 being capable of synchronous axial system.Certainly, for the first shaft gear 322 and the connected mode of first axle 321, with
And second shaft gear 332 and the second axle 331 connected mode, or diversified, such as the first shaft gear 322 and first
Axle 321 can adopt the connected mode of welding, the second shaft gear 332 and the second axle 331 to adopt the connected mode of welding.Again
As the first shaft gear 322 and first axle 321 can adopt integrally formed design, the second shaft gear 332 and the second axle 331
Integrally formed connected mode can also be adopted.As long as can reach in this utility model embodiment the first shaft gear 322 with
The technique effect of the synchronous axial system of the first axle 321, the second shaft gear 332 and the synchronous axial system of the second axle 331.Likewise,
Due to there is 2 shaft gears (the first shaft gear 322 and the second shaft gear 332), the number or even startup for starter receiver 31
Device 34 can also all be respectively 2.That is, the first shaft gear 322 matches a starter receiver 31 and a trigger 34, the second axle
Gear 332 matches a starter receiver 31 and a trigger 34, or the first shaft gear 322 matches a starter receiver 31,
Second shaft gear 332 matches a starter receiver 31, and a trigger 34 starts two starter receivers 31 and rotates etc. simultaneously,
As long as finally can realize driving the axle 331 of first axle 321 and second to be rotated, then it is applied to this utility model.
Sum it up, as stated above, revolve for how trigger 34 starts the axle 331 of first axle 321 and second
Turn, this utility model embodiment is not limited, can be with using the above-mentioned three kinds of startup structures at least describing and mode, certainly
Can be using other startup structures and the mode that this utility model embodiment is provided not be limited to, as long as can be real during being suitable for
Existing trigger normally starts the axle 331 of first axle 321 and second and is rotated, and suitable for this utility model, here is omitted.
