Description

An airborne rain-increasing flame bar and its spreader

technical field

The invention belongs to the technical field of artificial rain-enhancing equipment, in particular to an airborne rain-enhancing flame bar and a spreader thereof.

Background technique

Among the various catalytic methods of artificial weather modification, directing the aircraft into the clouds is the best solution. For a wide range of weather processes, the aircraft can directly sow the catalyst into the predetermined part of the cloud, the aircraft has strong maneuverability, and has the characteristics of uniform sowing, large operating area, and wide influence range. Whether it is artificial rain enhancement to meet agricultural drought resistance, or to carry out data detection and targeted scientific research, aircraft have obvious advantages.

At present, the internal structure of the airborne rain-enhancing flame strips used for domestic aircraft rain-enhancing operations is basically the same, and there are only two external structures. Specially designed and applied, the first type of airborne rain-enhancing flame rod is connected to the corresponding through hole on the spreader through a through hole at the end of the flame rod, and the second type of flame rod is fixed through the flame rod. One end of the strip squeezes two binding posts which are provided with elastic force by a spring, and the poles are rotated and clamped. The two bayonet pins on the flame strip are limited and fixed in the bayonet slot of the spreader.

After market application, the above-mentioned two types of airborne rain-enhancing flame bars and spreaders have certain potential safety hazards in actual use.

The first type of airborne rain-increasing flame bar is fixed to the spreader through the pin limit. The other parts of the flame bar have no support. The center of gravity of the flame bar is in a suspended state. During the take-off, flight and landing of the aircraft, the flame bar is connected at the joint. It is a torsion point, and it is always in the state of shaking, shaking, pulling and twisting the pin, and the molding material of the flame bar is FRP, and the joint is drilled with a through hole for connecting with the spreader, making it the weakest part of the entire flame bar. It may cause the flame strip to be destroyed by the through hole as the tearing point, and the flame strip will fall off in flight, which is extremely dangerous! And a similar situation has indeed occurred in actual flight application operations.

The second type of airborne rain-increasing flame bar is fixed in the slot of the spreader by extruding two terminals that provide elastic force through springs at one end of the flame bar. Although most of the strips are wrapped and supported, the main points of force and anti-fall are concentrated on the spring and the bayonet. During the take-off, flight and landing of the aircraft, the flame bar and the spreader are always under force and vibration. After long-term compression and deformation of the spring, there is a limit time when the spring loses its elasticity. The bayonet is fastened into the flame bar through threads and anti-loose heat-resistant glue. Under such severe vibration and high-temperature combustion inside the flame bar, there will be a time when it will come off and take effect. Once the detent or spring is effective, the flame bar will fall directly from the spreader, which is extremely dangerous! And a similar situation has indeed occurred in actual flight application operations.

To sum up, the existing airborne rain-increasing flame strips are in danger of falling off during installation, which is very unsafe to use and has a great potential safety hazard. The connection of the strip is relatively concealed, which is not convenient for safety inspection and maintenance.
