To summarize, in this embodiment, the expansion part (15 XX) mainly depends on the gas pressure of the gas chamber (28 XX) during the centripetal movement, and the position fine adjustment assembly mainly depends on the gas pressure introduced into the outer cavity (22 XX) during the centrifugal movement, so that the precision of the movement track of the expansion part (15 XX) and the mirror synchronization of the two corresponding expansion parts (15 XX) can be ensured with a very small force.

In addition, in the embodiment, the power supply of the independent controller (31 XX) can be realized by arranging an armature on the shaft (12 XX), supplying power from the outside through a brush, arranging a generator on the shaft (12 XX) or both, so as to improve the safety and the stability.

The mounting arrangement of the above embodiment is accomplished, and the working principle of the thrust generator is specifically set forth below.

The thrust generator starts to rotate by driving the shaft (12 XX) by external power, namely, a pair of rotating parts starts to rotate, and the rest parts are operated in a matching way, and finally, the operation effect of the figures 6-9 is achieved.

As shown in reference to figures 6-9,

It can be seen that the expansion parts (15 XX) on one rotation part all have the same movement locus, and the dotted lines indicated in fig. 6 to 9 show the rough movement locus of each expansion part (15 XX).

For the sake of accurate and clear description, a rectangular coordinate system is introduced in fig. 6-9, the first rotating portion rotates 0 degrees in the + X-axis direction and 360 degrees in a counterclockwise rotation, and the second rotating portion rotates 360 degrees in a clockwise rotation in the-X-axis direction and 0 degrees in a-X-axis direction; the first rotating part and the second rotating part are mirror images of each other by taking the straight line where F1 is located as a center line.

The whole machine working process is that, the expansion part (15 XX) is in the maximum rotation radius at 0 degree, at the moment, the expansion part (15 XX) is about to do centripetal movement, the first position fine adjustment component is matched to act, namely the push rod drive (19 XX) releases the static locking of the push rod (18 XX) and retracts centripetally, and the expansion part (15 XX) is forced to do centripetal movement by the air pressure of the air chamber (28 XX), so that the expansion part (15 XX) reaches the minimum rotation radius at 180 degrees.

specifically, when a certain rotating speed is reached, the air pressure value in the air chamber (28 XX) is synchronously regulated and controlled to be required for setting, the set value can overcome the centrifugal force of the expansion part (15 XX) caused by rotation, and slightly surplus, the expansion part (15 XX) can be pushed to move centripetally, a track similar to an involute is formed at the rotation angle of 0-180 degrees, other interference factors such as the friction force between the expansion part (15 XX) and the fixed part (14 XX), factors causing the expansion part (15 XX) to deviate from the designed track due to insufficient accurate air pressure and the like are adjusted by the position fine adjustment component.

Then, starting from 180 degrees, the centrifugal motion control assembly drives the telescopic part (15 XX) to do centrifugal motion, namely, the outer cavity (22 XX) is filled with gas, the gas pressure is increased, the telescopic part (15 XX) is pushed to do centrifugal motion, the maximum rotation radius is reached at 270 degrees, the gas pressure of the outer cavity (22 XX) starts to be released at the moment, then the centripetal force of the telescopic part (15 XX) is mainly provided by the gas pressure of the gas chamber (28 XX), meanwhile, the push rod (18 XX) of the position fine adjustment assembly moves in a centripetal mode to be locked, the centrifugal motion is free, the rotation radius of the telescopic part (15 XX) is fixed, then the telescopic part (15 XX) does circular motion to the position of 360 degrees.

The principle of thrust generation is further explained by mechanical analysis.

Firstly, only analyzing the influence of the kinetic energy change of the telescopic part (15 XX) on the whole machine, and analyzing a pair of corresponding telescopic parts, such as (1511) and (1521), as can be seen from fig. 6, the telescopic part (15 XX) performs centripetal motion at 0-90 degrees, which can promote the rotation speed of the rotating part to increase, and if the rotation speed of the rotating part does not increase, the whole machine tends to move towards the + Y-axis direction; referring to fig. 7, it can be seen that, at 90-180 degrees, the two telescopic parts (15 XX) continue to move centripetally, which also promotes the rotation speed of the rotating part to increase, if the rotation speed of the rotating part does not increase, the whole machine tends to move in the-Y axis direction;

Referring to fig. 8, from 180 degrees to 270 degrees, a pair of telescopic parts (15 XX) do centrifugal motion, which will result in the rotation speed of the rotating part decreasing, if the rotation speed of the rotating part does not decrease, the whole machine tends to move in the + Y axis direction.

referring to fig. 9, it can be seen that 270 degrees to 360 degrees, that is, 0 degree, the motion trajectory of the expansion part (15 XX) is a circle, and in this process, because the centripetal force provides the air pressure mainly from the air chamber (28 XX), only the kinetic energy change of the expansion part (15 XX) is analyzed, and the expansion part has no influence on the whole motion trend.

It can be seen that, during the operation of the thrust generator, each pair of the telescopic parts (15 XX) has the above-mentioned motion track and action effect, so that the overall operation state can be obtained only by analyzing the state that all the operation units rotate through 90 degrees at the same time, and from the overall view, the overall operation state can also be obtained by analyzing when the telescopic parts (1511) and (1521) are respectively located at 0 degree, as can be seen from fig. 6, (1511) and (1521) will generate the motion trend towards the + Y axis direction, and (1512) and (1522) will generate the motion trend towards the-Y axis direction, and it can be found that the motion trends of the two will be approximately cancelled.

meanwhile, (1513) and (1523) will generate the motion trend of + Y-axis direction.

In addition, (1514) and (1524) do circular motion, and the centripetal force provides air pressure from the air chamber, so the motion process does not affect the whole machine in the Y axis.

finally, in a general view, the influence of the change of the kinetic energy of the telescopic part on the rotating part, specifically, the increasing trend of the rotating speed of the rotating part caused by the centripetal motion of (1511) (1521) (1512) (1522) can be balanced by the decreasing trend caused by the centrifugal motion of (1513) (1523).

From the above, it can be seen that, when the telescopic parts interact with the whole machine alone, each telescopic part always generates impulse-type thrust in the + Y-axis direction to the whole machine during the rotation of 180-270 degrees in the working process of the thrust generator.

In addition, the forces that have the greatest influence on the whole machine are the air pressure in the air chamber and the air pressure in the outer cavity, and the analysis is as follows;

Firstly, the pressure born by the inner wall of the air chamber in the embodiment has four notches, namely four air cylinders, and the four notches are symmetrical in pairs, in the operation process of the thrust generator, when the air cylinders rotate by 180-270 degrees, the pressure at the notches of the air chamber is increased by the air pressure of the outer cavity to push the expansion part to do centrifugal motion, the air pressure is transmitted to the axle center, and the notches of the rest air cylinders are in an emptying state, so that the whole machine can generate a force in the direction of + Y axis.

More specifically, the gas pressure provided to the expansion part in the gas chamber is larger than the centripetal force required by the maximum rotation radius of the expansion part, and the centrifugal force of the expansion part is at the minimum value when the expansion part is at the 180-degree position, so that an additional force is required to push the expansion part to do centrifugal motion, the additional force is the gas pressure of the outer cavity in the embodiment, the gas pressure acts on the expansion part on one side and acts on the axis on the other side, therefore, the thrust generator can generate a force with pulse effect as a whole, and the force is jointly marked as F1 with the motion trend generated by the change of the kinetic energy of the expansion part.

In addition, the spur rack in the embodiment can be regarded as a part of the telescopic part, and the worm is arranged on the driving motor and is matched with the spur rack to have a self-locking function.

obviously, there are many embodiments to the work unit, and the fixed part is at the rotation plane even stagger setting more optimization, can let thrust output more smooth, and the rotation speed fluctuation of rotation portion is littleer.

it can be seen that embodiment 1 is suitable for medium and large applications, for example, if the rotating speed is large, the linear bearings are more suitable to be arranged at the two ends of the fixing part, and in addition, the position fine adjustment assembly in the large embodiment can simultaneously have the function of the centrifugal motion control assembly, so that the centrifugal motion control assembly in embodiment 1 is omitted.

It is apparent that when the rotating part is installed in the air chamber, the fixed part may be a piston and the telescopic part may be a cylinder.

the telescopic sleeve is of the piston and cylinder type, the parts in frictional contact may be provided with wear compensation means.

And the telescopic sleeve is made of corrugated pipes, so that the miniature embodiment is more compact and economical.

It is obvious that there are many ways to implement the centripetal motion control unit, the centrifugal motion control unit, the position fine-tuning unit, etc. and combinations thereof, and those skilled in the relevant art can reasonably foresee and imagine the embodiments without departing from the spirit of the present invention and should be considered as being within the scope of the present invention.

in this embodiment 1, the movement locus of the telescopic part in fig. 6 to 9 does not limit the present invention, the angle value of the action boundary of the telescopic part mentioned in embodiment 1 does not limit the present invention, embodiment 1 is intended to clearly express the inventive principle, and the action of the telescopic part can be arbitrarily adjusted in the radial direction, that is, the thrust direction can be arbitrarily adjusted by the coaxial 4 rotating parts in fig. 10.

the installation of each component on the working unit is configured to consider the rotation balance, which is not described herein.

Embodiments are designed coaxially, so that to allow for balance, the number of working units is an integer multiple of 2 pairs, as far as a single thrust generator is used alone.
