Description

Technical Field

[0001] The present application relates to the field of flexible aircraft, and in particular to a flexible electrode-based ion wind thrust device. Background Art

[0002] Flexible aircraft, with its unique flexible wing design, can ensure greater lift while also having the ability to fly for a long time. This technological innovation has attracted widespread attention at home and abroad. Ion wind thrusters, with their unique advantages of not requiring additional working fluid consumption and being able to directly generate straight-line wind force, are regarded as the cutting-edge development direction of future aircraft power systems and have wide application value in the power field. However, the limitation of current propulsion technology is that it is difficult to flexibly arrange it according to the shape of the aircraft, which greatly limits its wide application in practical applications. Therefore, it is particularly important to develop flexible ion wind thrusters that can adapt to and integrate into the shape of aircraft.

[0003] In terms of the adjustment mechanism of flexible aircraft, morphing aircraft, as a type of aircraft that can dynamically adjust its shape according to the flight state to improve aerodynamic performance, is gaining increasing attention. By changing its aerodynamic shape, morphing aircraft can maintain optimal aerodynamic efficiency and maneuverability under various working conditions, and flexible wings are the key development direction in this technological trend. However, most of the current control methods for flexible wings rely on traditional mechanical adjustment methods, which often have disadvantages such as heavy weight, complex structure, and low control frequency, making it difficult to meet the urgent needs of flexible wings for timely control.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] In an exemplary embodiment, Figure 1 As shown, the present application provides a flexible electrode-based ion wind thrust device, which is applied to a flexible aircraft and includes:

[0026] The ion wind propulsion module is attached to the flexible wing of the flexible aircraft and is used to generate an external electric field and control the gas flow of the flexible wing through the external electric field.

[0027] The power supply module is connected to the ion wind thruster module and is used to supply power to the ion wind thruster module.

[0028] The ion wind propeller module comprises a flexible insulating medium 3 and a conductive film electrode; the conductive film electrode is attached to the flexible insulating medium.

[0029] Specifically, there are one or more ion wind thruster modules.

[0030] Specifically, the arrangement of multiple ion wind thruster modules is in parallel. The ion wind thrusters can also be arranged at different positions according to the requirements of the flexible aircraft.

[0031] When the ion wind thrusters are arranged in parallel, the voltage output end of the power supply module is connected to the high-voltage ends of multiple ion wind thrusters, and the ground output end of the power supply module is connected to the ground ends of multiple ion wind thrusters, forming a loop between the high-voltage electrode and the ground electrode side, thereby generating a macroscopic thrust effect.

[0032] Specifically, the power supply module is any one of an AC power supply and a pulse power supply, or a combination of an AC power supply and a pulse power supply, or a combination of a DC power supply, an AC power supply and a pulse power supply.

[0033] Specifically, the conductive film electrode includes a high-voltage electrode 1 and a grounding electrode 2; the high-voltage electrode 1 is connected to the high-voltage output end of the power supply module, and the grounding electrode 2 is connected to the grounding output end of the power supply module; the flexible insulating medium 3 is arranged between the high-voltage electrode 1 and the grounding electrode 2.

[0034] Specifically, the conductive film electrode is attached to or printed on the flexible insulating medium 3, and the structures of the two can be adjusted according to actual working conditions.

[0035] Specifically, the material of the flexible insulating medium 3 is one of plastic material, rubber material and polymer insulating medium material, or a combination of plastic material, rubber material and polymer insulating medium material. The material of the flexible insulating medium 3 can also be the insulating material of the flexible aircraft itself (i.e., the insulating material 5 of the flexible wing).

[0036] In terms of the pasting method, in addition to the conductive film electrode, the flexible insulating medium 3 and the flexible wing being pasted by gluing, the conductive film electrode, the flexible insulating medium 3 and the flexible wing can also be connected by various methods such as bolts.

[0037] Specifically, when the flexible wings of the flexible aircraft move, the ion wind propulsion module undergoes a shape change.

[0038] The ion wind thruster module and the power supply module constitute a flexible ion wind thruster. The flexible ion wind thruster is arranged on the surface of the flexible aircraft during installation. It can be arranged at a specific position of the aircraft according to the overall flow field design of the flexible aircraft. At the same time, it can meet the deformation requirements of the flexible aircraft and move with the flexible aircraft. That is, the flexible ion wind thruster has the ability to work under large deformation conditions and can change its shape following the movement of the flexible aircraft. The flexible ion wind thruster can be arranged at a specific position of the flexible aircraft according to demand. By turning on the excitation power supply and adjusting the output voltage, a macroscopic airflow movement is generated. The airflow direction is from the high-voltage electrode to the ground electrode, thereby generating a macroscopic thrust effect.

[0039] In an exemplary embodiment, the power supply module is also used to adjust the external power supply voltage and frequency parameters to control the ion wind thruster module to generate different external electric fields.

[0040] Specifically, under the condition of fixing the flexible ion wind propeller, by adjusting the voltage, frequency and other parameters of the external power supply module, the wind speed generated by the propeller can be controlled, the final macro thrust can be adjusted, and the flow control effect on the flexible aircraft can be produced.

[0041] In terms of control methods, multi-frequency and multi-excitation source coordinated control is adopted to form coordinated matching of multiple frequency bands in the control method to achieve multi-time scale control of the overall flow.

[0042] The beneficial effects of the flexible electrode-based ion wind thrust device proposed in this application are mainly manifested in:

[0043] (1) Through the cooperation between the ion wind thruster module and the power supply module, the ion wind thruster can generate gas flow by itself under the action of an external electric field. By adjusting the external excitation of the flexible ion wind thruster, effective real-time adjustment of wind speed, direction, etc. can be achieved, and the influence of the external flow field on the flexible aircraft can be quickly resisted, thereby improving the timeliness of the flexible wing regulation and thus improving the stability of the flexible aircraft.

[0044] (2) By adjusting the external power supply voltage and frequency parameters of the power supply module, the ion wind thruster module is controlled to generate different external electric fields, so that the ion wind thruster module generates gas flows of different intensities, thereby adjusting the gas flow as the external flow field changes, thereby improving the flexibility of flexible wing control.

[0045] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
