[0002] Low-altitude airships utilize gas to provide lift and achieve controllable flight through a power and control system, offering advantages such as large payload capacity and long flight time. Existing low-altitude airships generally use fuel engines or electric motors to drive propellers, inevitably generating noise and pollutants. With green and environmentally friendly concepts becoming mainstream, quiet and clean propulsion has become an urgent need in the field of low-altitude airship research. Summary of the Invention

[0003] Purpose of the invention: To address the aforementioned existing technologies, a low-noise, pollutant-free low-altitude airship is proposed.

[0004] Technical solution: A low-altitude silent airship using ion wind power, comprising a hull, several corona ion wind electric propulsion devices, and a power supply system; Several of the aforementioned corona ion wind power propulsion devices are connected to the outside of the hull; the power system is used to provide operating power to the corona ion wind power propulsion devices. The corona ion wind power propulsion device includes a multi-ringed collector electrode and a sawtooth-shaped discharge electrode. Both the multi-ringed collector electrode and the sawtooth-shaped discharge electrode are made of insulating material and then electroplated, and are respectively fixed on the collector electrode insulating bracket and the discharge electrode insulating bracket through embedded connections. The multi-ringed collector electrode is connected to the negative output terminal of the power system by a high-voltage wire, and the sawtooth-shaped discharge electrode is connected to the positive output terminal of the power system by a high-voltage wire.

[0005] Furthermore, the power system is installed on the hull and includes a power supply, a controller, and a boost module. The boost module is used to boost the output voltage of the power supply to the operating high voltage of the corona ion wind power propulsion device, and the controller is used to control the on / off of the power output of the power system.

[0006] Furthermore, the current collector insulating bracket and the discharge electrode insulating bracket are fixed to the insulating base, and the multi-ring current collector and the serrated discharge electrode are arranged opposite to each other; the corona ion wind power propulsion device is connected to the hull through the insulating base.

[0007] Furthermore, the hull includes an airtight airbag and a tail fin, the airtight airbag being filled with buoyancy gas to provide static lift for the airship.

[0008] Furthermore, the aforementioned corona ion wind propulsion devices are arranged in a distributed thrust structure on the outside of the airship.

[0009] Furthermore, the plurality of corona ion wind propulsion devices are arranged on the outer side of a transverse section of the hull and distributed at circumferential intervals on the lower half-circle of the transverse section.

[0010] Furthermore, each of the aforementioned corona ion wind propulsion devices is connected in parallel to the output terminal of the power system.

Detailed Implementation

[0016] The invention will now be further explained with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, a low-altitude silent airship using ion wind power consists of a hull 1, ten corona ion wind electric propulsion devices 3, and a power supply system.

[0018] The airtight gasbag of hull 1 is made of ring-reinforced polyurethane and neoprene rubber, and is filled with buoyancy gas to provide static lift for the airship. The tail fin 7 is located at the stern of hull 1 and is made of polystyrene foam.

[0019] The core components of the corona ion wind power propulsion device 3 are a multi-ringed collector 301 and a serrated discharge electrode 302 arranged opposite to each other. Both the multi-ringed collector 301 and the serrated discharge electrode 302 are made of epoxy resin and electroplated, and are respectively welded to the corresponding collector insulating bracket 303 and discharge insulating bracket 304 in an embedded manner. Both the collector insulating bracket 303 and the discharge insulating bracket 304 are made of epoxy resin or other insulating materials. The collector insulating bracket 303 and the discharge insulating bracket 304 are welded and fixed to an insulating base 8, which is also made of epoxy resin or other insulating materials and is mainly used to fix and support the collector insulating bracket 303 and the discharge insulating bracket 304.

[0020] Specifically, on the sawtooth discharge electrode 302, multiple sawtooth discharge electrodes with their tips facing the multi-ring collector electrode 301 are arranged circumferentially to form a ring structure. The sawtooth structure creates a high electric field intensity region at each tooth tip, significantly reducing the corona initiation voltage. Compared to smooth electrodes or single-point electrodes, the sawtooth design provides a large number of discharge points within the same area, greatly improving ion generation efficiency. At the same time, the sawtooth arrangement can directionally guide the corona discharge direction, making the ion wind more concentrated towards the collector electrode and reducing energy waste.

[0021] The multi-ring collector 301 has multiple concentrically arranged ring-shaped collectors. The multi-ring structure creates a multi-level electric field region, ensuring that ions are continuously accelerated by the electric field force throughout their motion, rather than just in the initial stage. Compared to a single-planar collector, the multi-ring structure extends the ion path, increasing the number of collisions with air molecules and improving energy transfer efficiency. Furthermore, the ring structure guides the airflow to form a more ordered flow pattern, reducing turbulence and energy dissipation, and enhancing the directionality of the airflow.

[0022] The combination of the serrated discharge electrode 302 and the multi-ring collector electrode 301 forms a highly optimized electric field distribution. The three-dimensional electrode structure creates a larger effective working area within a limited volume, and the energy-to-kinetic energy conversion efficiency of this structure far exceeds that of the traditional planar design.

[0023] Each corona ion wind propulsion device 3 is welded and fixed to the outside of the hull 1 via an insulating base 8. In this embodiment, ten corona ion wind propulsion devices 3 are arranged on the outer surface of a transverse section in the middle of the hull 1, and are distributed circumferentially at intervals on the lower half of the transverse section. Each corona ion wind propulsion device 3 is connected in parallel to the output terminal of the power system.

[0024] The power system is attached to the lower middle part of the hull 1 and is used to provide operating power for the corona ion wind turbine propulsion device 3. The power system consists of a power supply 5, a controller 4, and a boost module 2. The boost module 2 is used to boost the output voltage of the power supply 5 to the high operating voltage of the corona ion wind turbine propulsion device 3, and the controller 4 is used to control the on / off of the power output of the power system.

[0025] The power supply 5, controller 4, and boost module 2 are connected sequentially via wires. Power supply 5 outputs 24V, and boost module 2 outputs voltages above 40KV. The multi-ring collector 301 is connected to the negative output terminal of the power system via a high-voltage wire 6, and the sawtooth discharge electrode 302 is connected to the positive output terminal of the power system via the high-voltage wire 6. The high-voltage wire 6 is a single-core wire with an insulating layer. Controller 4 can control the opening and closing of the ion wind propulsion device via a wireless remote control switch.

[0026] In some embodiments, the corona ion wind propulsion device can also be arranged in other different positions on the airship to form a distributed thrust structure.

[0027] The working principle of the low-altitude silent airship of this invention is as follows: When the power is turned on, a corona discharge phenomenon will occur on the sawtooth discharge electrode 302 under the action of a 40KV voltage; the gas ions generated by the corona discharge leave the sawtooth discharge electrode 302 and drift toward the multi-ring collector electrode 301.

[0028] In the presence of a large number of neutral gas molecules, these molecules are accelerated by collisions with gas ions as they drift between the serrated discharge electrode 302 and the multi-ring collector 301, eventually escaping the corona ion wind propulsion device and generating airflow. At this point, the combined force of the gas ions, the serrated discharge electrode 302, and the multi-ring collector 301 is not zero, resulting in a thrust pointing from the multi-ring collector 301 to the serrated discharge electrode 302. The magnitude of this thrust is the spatial integral of the product of the gas ion charge density and the electric field strength between the serrated discharge electrode 302 and the multi-ring collector 301. Experimental results show that, under standard atmospheric pressure, it generates 3-5 times the thrust of a conventional ion wind propulsion device, and the noise level can be controlled below 20 decibels. Therefore, it has promising application prospects.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
