The working principle of the driving mechanism 50 according to the present invention is described separately according to the above two embodiments:

the driving mechanism 50 of the aerial simple aircraft comprises an initial state and a working state, when the system is in the working state, the pressure in the first elastic cavity 2 is between a first pressure threshold and a second pressure threshold, and when the pressure in the first elastic cavity 2 is reduced to the first pressure threshold, the control device controls the pump body to supplement fluid into the first elastic cavity 2; when the pressure inside the first elastic cavity 2 rises to the second pressure threshold, the control device controls the pump body to stop supplying fluid into the first elastic cavity 2, and always keeps the pressure inside the first elastic cavity 2 between the first pressure threshold and the second pressure threshold so as to keep a continuous working state, specifically:

using fig. 6 and 7 asFor example, the driving mechanism 50 operates as follows:

initial state:the initial state can be realized by the control device 19, specifically, the first accommodating space 4 is a sealed negative pressure space, the first elastic cavity 2 is in a hollow state without fluid inside, the control device 19 controls the second valve 11 to open, the fluid enters the second accommodating space 6, the control device 19 receives the flow information of the first flowmeter in real time, when the fluid in the second accommodating space 6 is added to a preset volume, the control device 19 controls the second valve 11 to close, at this time, the motor is started and the pump body is driven to rotate under the control of the control device 19, the fluid in the second accommodating space 6 is driven into the first elastic cavity 2 through the pump body, the fluid in the first elastic cavity 2 gradually changes and expands to drive the sliding member 3 to move close to the second accommodating space 6, and the volume of the first accommodating space 4 gradually increases, the control device 19 receives the flow information of the second flow meter in real time, when the fluid in the first elastic cavity 2 is added to the preset volume, that is, the pressure inside the corresponding first elastic cavity 2 is increased to the second pressure threshold, at this time, the control device 19 controls the motor to stop rotating, and at this time, the setting of the initial state of the device is completed.

The working state is as follows: when the invention works, on one hand, because the first elastic cavity 2 has elasticity, the first elastic cavity 2 which is filled with fluid and is expanded has resilience; on the other hand, since the first accommodation space 4 is a negative pressure chamber, the second accommodation space 6 generates a pressure difference with the first accommodation space 4, and thus the slider 3 tends to move closer to the first accommodation space 4.

Further, during operation, the control device 19 controls the first valve 10 and the second valve 11 to open, on one hand, the first elastic cavity 2 drives the fluid in the first elastic cavity 2 to flow out from the third pipeline 9 under the action of self-resilience force, on the other hand, under the action of atmospheric pressure, the pressure difference generated between the second accommodating space 6 and the first accommodating space 4 drives the sliding member 3 to move close to the first accommodating space 4, so that the sliding member 3 not only presses the first elastic cavity 2 to enable the fluid in the first elastic cavity 2 to flow out rapidly, but also can realize automatic fluid supplement in the second accommodating space 6 under the action of atmospheric pressure, when the residual fluid in the first elastic cavity 2 reaches a preset volume, namely when the pressure corresponding to the interior of the first elastic cavity 2 is reduced to a first pressure threshold value, the control device 19 controls the pump body to rotate again, and the fluid in the second accommodating space 6 is supplemented in the first elastic cavity 2 again through the pump body, until the pressure in the first elastic cavity 2 rises to the second pressure threshold again, the operation is repeated in this way, so that continuous fluid in the first elastic cavity 2 is ensured to flow out through the third pipeline 9, and the requirement of the device is met.

It should be noted that, during the whole operation, the control device 19 can control the opening degree of the first valve 10 according to actual needs, and when the opening degree of the first valve 10 is smaller, the flow rate of the fluid ejected from the third pipeline 9 is fast; when the opening degree of the first valve 10 is large, the flow velocity of the fluid sprayed out of the third pipeline 9 is low, so that the requirements of different energy release strengths are met, controllable thrust is realized, and the actual requirement of flight thrust is met.

Taking fig. 3 as an example, the driving mechanism 50 works as follows:

initial state:the initial state can be controlled by the control device 19, specifically, the third accommodating space 13 is filled with fluid, the first elastic cavity 2 is in a hollow state without fluid inside, the fifth valve 18 is opened, the control device 19 controls the motor to start and drive the pump body to rotate, the fluid in the third accommodating space 13 is pumped into the first elastic cavity 2 through the pump body, when the fluid in the first elastic cavity 2 is added to a preset volume, namely, the pressure inside the first elastic cavity 2 is increased to a second pressure threshold value, the control device 19 controls the motor to stop rotating, and the setting of the initial state of the device is completed.

The working state is as follows: because the first elastic cavity 2 has elasticity, the first elastic cavity 2 filled with fluid and expanded has resilience, so that the elastic force exists for driving the internal fluid to flow out, when the pump works, the control device 19 controls the fourth valve 17 and the fifth valve 18 to be opened, on one hand, the first elastic cavity 2 drives the fluid in the first elastic cavity 2 to flow out from the sixth pipeline 16 under the action of the resilience, on the other hand, the control device 19 controls the opening degree of the fifth valve 18 according to the volume of the first elastic cavity 2 excluding the fluid, and fills the corresponding volume of the fluid into the third accommodating space 13, when the residual fluid in the first elastic cavity 2 reaches the preset volume, namely when the pressure in the corresponding first elastic cavity 2 is reduced to the first pressure threshold value, the control device 19 controls the pump body to rotate again, and the fluid in the third accommodating space 13 is filled into the first elastic cavity 2 again through the pump body, until the pressure in the first elastic cavity 2 rises to the second pressure threshold again, the above steps are repeated to ensure that continuous fluid in the first elastic cavity 2 flows out through the sixth pipeline 16, so as to meet the requirement of the device.

It should be noted that, during the whole operation, the control device 19 can control the opening degree of the fourth valve 17 according to actual needs, and when the opening degree of the fourth valve 17 is small, the flow rate of the fluid flowing out of the sixth pipeline 16 is fast; when the opening degree of the fourth valve 17 is large, the flow rate of the fluid flowing out of the sixth pipeline 16 is slow so as to meet the requirements of different energy release strengths, and the counterforce meets the actual requirement of the flight thrust.

The first pressure threshold and the second pressure threshold in the present invention refer to pressures that ensure the system to work continuously, and the pressure inside the first elastic cavity 2 between the first pressure threshold and the second pressure threshold can ensure that the fluid inside the first elastic cavity 2 flows out continuously and the control of the flow rate is realized by the control of the control device 19.

Further, the first pressure threshold and the second pressure threshold may be monitored by setting a flow meter, and may also be monitored by setting a pressure sensor, when a flow meter is used, how much of the flow output by the control device 19 through the first elastic cavity 2 is output as a control command, when a pressure sensor is used, the control device 19 outputs a control command through the obtained pressure inside the first elastic cavity 2, and when the pressure inside the first elastic cavity 2 is increased due to a change of fluid pressure or decreased due to a change of fluid pressure, the control device 19 executes the control command through information obtained in real time.

The invention provides a low-speed aerial vehicle.A driving mechanism 50 can work under the action of an elastic cavity and the external atmospheric pressure and can also work under the action of the self resilience force of the elastic cavity only based on the fluid air, and the interlocking control is realized by a control device, a pump body and valves, so that the stable and controllable flow rate or flow of fluid is realized, and the low-speed aerial vehicle is noiseless, simple in structure, convenient to operate and wide in application.

In a variation, the fluids in the plurality of driving mechanisms 50 are set to be different fluids, for example, the fluid in one part of the driving mechanisms 50 is a combustible agent, the fluid in the other part of the driving mechanisms 50 is a combustion improver, and the ends of the fluid outlet pipes in the two parts of the driving mechanisms 50 respectively enter the corresponding mixing chambers in a one-to-one correspondence manner and are ignited and combusted by the ignition device to realize the injection propulsion force after the fluid expands, thereby achieving the purpose of fast flight.

Furthermore, the adding amount of the combustible fluid stored in the storage device can be added according to the requirement of the flight mission, the flight mission with a set distance can be realized, for example, the aircraft is required to fly for 30 kilometers, and the combustible fluid with a corresponding volume can be added, so that the aircraft can complete the flight mission for 30 kilometers.

Furthermore, the combustible fluid can be a combustible gas, such as hydrogen, or a combustible liquid, such as ethanol, and the combustion improver can be air or oxygen, and is reasonably arranged according to the actual condition of the device; in addition, the fluid outflow pipeline is made of high-temperature-resistant materials with certain strength, can bear the impact of instantaneous combustion expansion force, and does not have chemical reaction with the combustible agent and the combustion improver.

The working principle of the aerial simple aircraft is as follows:
