Problems solved by technology

[0007] Airplane sowing method (manned aerial sowing method): install a smoke generator on a small manned aircraft, start the smoke agent combustion after flying to the designated airspace, and spread silver iodide in the cloud layer. This method has a large operating area, high efficiency, and low direct cost. , but the adaptability is poor. In our country, the total cost of this method is higher than that of the rocket launch method. This is mainly related to the unpopularity of aircraft in our country. Military aircraft are generally used, and the cost of renting an aircraft is very high. In addition, artificial rainfall is more expensive than conventional flight. It is more dangerous, and the aerial seeding method must not be used for hail suppression

Embodiment 1

[0038] This embodiment provides a remote control aircraft for hail suppression and rain, including the aircraft body, the aircraft body is an over-the-horizon remote control aircraft, which has the ability to resist bad weather, good economy, strong endurance, and can operate within a radius of 50-100km. Inner circle; the flight speed is 50-100km / h, the take-off and landing distance: 20-50 meters, the requirements for the take-off site are relatively low, no special airport is required, and the adaptability is strong; and the aircraft body is equipped with an emergency parachute to ensure safety. The wings of the aircraft body are fixed-wing, which can be made of ordinary aviation aluminum or composite materials, or flexible delta wings, umbrella wings, or inflatable wings; the fuselage is located under the wings (suspension type) , The wing has a large lift and good safety. After being disturbed by strong wind, it has the ability to automatically return to the flying state, an...

Embodiment 2

[0053] A hail and rain suppression method, mixing silver iodide with adhesives and oxidants to make a smoke agent, and filling the smoke agent in a combustion tube; hanging the combustion tube on the fuselage of a remote-controlled aircraft, when the remote-controlled aircraft reaches a predetermined height and airspace Finally, ignite the combustion tube to complete the spreading of silver iodide.

[0054] Among them, the remote control aircraft uses a rotax-582 engine (weight 50kg), which drives the propeller (weight 3kg), wing weight: 50kg, plus the fuselage, control devices, etc., the maximum empty weight of the aircraft: 200 kg, can be Carrying load: 300kg; aircraft speed: 100km / h, aircraft range: 500km. The flying time after each launch is 5 hours.

[0055] Install the combustion tube outside the fuselage or the lower part of the wing of the remote control aircraft. When the remote control aircraft reaches the predetermined height and airspace, ignite the combustion tub...

Embodiment 3

[0058] This embodiment is an improvement on Embodiment 2, and its improvement lies in: a method for hail suppression and rainfall, in which a rocket engine is installed on a remote-controlled aircraft, and silver iodide is mixed with an adhesive and an oxidant to make a smoke agent, and filled with In the rocket engine, when the remote-controlled aircraft reaches the predetermined height and airspace, start the rocket engine, finish spreading the silver iodide, and generate thrust. The thrust of the rocket engine is about 30-50% of that of the piston engine.

[0059] When the aircraft takes off, the piston engine runs at full capacity, and when the aircraft cruises, the rocket engine starts to work, and the piston engine can be stopped or in an idle state. When the plane flies back, it is a descending flight and consumes almost no fuel.

[0060] If the load is 300kg, only 50kg of oil is needed, and the value is about 500 yuan; while the total weight of the smoke generator can ...

Abstract

The invention discloses a remote-controlled aircraft for hail mitigation and precipitation and a hail mitigation and precipitation method. The remote-controlled aircraft is adopted to scatter silver iodide in a cloud layer, the safety is better, airspace control is relatively loose, and the adaptability is strong. The silver iodide is dissolved in an acetone-alcohol solution, the use of ammonium chlorate is avoided, pollution is decreased, and the remote-controlled aircraft has better environmental protection property. In addition, explosive materials are avoided, the aircraft is safer, and inventory management, transportation management and operation management are loose to control. Wings are foldable and are convenient to store, transport and operate, and the cost is reduced. The acetone-alcohol solution containing the silver iodide is burned at the tail portion of a jet engine, corrosion of the jet engine is avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of hail and rain suppression, in particular to a remote-controlled aircraft for hail and rain suppression and a hail and rain suppression method. Background technique [0002] Humans first discovered that dry ice can cause rain clouds to produce ice crystals and immediately rain, and then found that silver iodide has a better catalytic rainfall effect, and also found that the higher the nucleation rate of silver iodide (the number of grains that can be produced per gram of silver iodide), the higher the rainfall. The higher the efficiency. Silver iodide, as a catalyst or nucleating agent for artificial rainfall, has been recognized as the best material at present. [0003] There are many ways to spread silver iodide in the cloud in microcrystalline state, such as: [0004] Solution combustion method: generally used to burn fog on the ground of the airport, and use the mountain and updraft to bring it into ...
