Abstract
The utility model relates to a composite nozzle of a hail-suppression and precipitation-enhancement rocket, which belongs to the technical field of rockets. The composite nozzle comprises a nozzle front-section metal shell, a one-time integrally formed plastic body, a non-metal throat liner and a nozzle rear-section metal shell. The nozzle front-section metal shell is inlaid at the front end of the plastic body, the nozzle rear-section metal shell is inlaid at the rear end of the plastic body, and the nozzle front-section metal shell and the nozzle rear-section metal shell jointly cover part of the plastic body. A throat of the plastic body is inlaid with the wash resistant and anti-ablative non-metal throat liner. The composite nozzle of the hail-suppression and precipitation-enhancement rocket is capable of reducing processes of a nozzle, shortening processing cycle, decreasing consumption of raw materials, remarkably improving economical efficiency, obviously reducing nozzle weight, decreasing eccentricity in geometry and enhancing performances of hail-suppression and precipitation-enhancement.
Description
Technical field
The present invention relates to the compound jet pipe of a kind of hail-proof rain-increasing rocket, belong to bullet arrow technical field.
Background technology
China is with a vast territory, the weather complexity, meteorological disasters such as arid, flood, hail frequently take place in China different regions, and hail suppression artificial rainmaking rocket bullet is as the power tool of weather modification, for preventing hail disaster, increase precipitation, alleviating arid threat, played positive effect.
The compound jet pipe of tradition hail suppression artificial rainmaking rocket bullet engine is made up of by being threaded jet pipe leading portion and jet pipe back segment two parts usually.The leading portion of existing compound jet pipe and back segment are made up of metal shell and the non-metallic inner liner with good thermal protective performance respectively.This compound jet pipe exists the problem of the following aspects to need to be resolved hurrily:
(1) compound jet pipe divides leading portion and back segment, and every section all by metal shell with non-metallic inner liner is two-layer forms.Process respectively adding man-hour needs, again by the composition that is threaded on the metal shell.And non-metallic inner liner adopts graphite usually, and its raw material are cylinders, need could form the structure that adheres to specification by twice processing of inner surface and outer surface.Compound jet pipe manufacturing procedure is many, thereby the process-cycle is long;
(2) the raw materials consumption amount of metal part and non-metallic part is all bigger in the compound jet pipe, has increased the processing and manufacturing cost; And cause compound jet pipe weight to lay particular stress on, restricted of the raising of hail suppression artificial rainmaking rocket bullet to a certain extent catalyst amount of carrying and range;
(3) section could form the geometric eccentricity that pneumatic profile has increased compound jet pipe after connecting before and after, has influenced the control of hail suppression artificial rainmaking rocket bullet flight attitude.
Summary of the invention
The present invention can solve the problem that manufacturing cost height, weight lay particular stress on and geometric eccentricity is bigger that the compound jet pipe of traditional hail-proof rain-increasing rocket exists, and provides a kind of hail-proof rain-increasing rocket compound jet pipe.
The objective of the invention is to be achieved through the following technical solutions:
The compound jet pipe of a kind of hail-proof rain-increasing rocket of the present invention comprises jet pipe leading portion metal shell, the plastic body by the compression moulding of plastics Integratively, larynx lining and jet pipe back segment metal shell; Wherein,
Plastic body comprises jet pipe converging portion, throat and expansion segment.Jet pipe leading portion metal shell is embedded in the front end outer wall of plastic body, and jet pipe back segment metal shell is embedded in the rear end outer wall of plastic body, and jet pipe leading portion metal shell and jet pipe back segment metal shell be the cover part plastic body altogether; The anti-anti-larynx lining of ablating that washes away is inlayed by the throat of plastic body.
Wherein, described jet pipe leading portion metal shell and described jet pipe back segment metal shell are suppressed respectively and are embedded in plastic body.
Wherein, described larynx lining is adhered to described plastic body, and the larynx lining can adopt nonmetallic materials for example for graphite, also can adopt metal material.Beneficial effect:
(1) compound jet pipe of the present invention can reduce the manufacturing procedure of jet pipe, shortens the process-cycle, and reduction metal and anti-washing away resist ablative nonmetal these raw-material consumptions, significantly improve its economy.
(2) because the consumption of metal reduces, adopt the compound jet pipe of the present invention can also obviously alleviate jet pipe weight, reduce the geometric eccentricity of jet pipe, improve its explosion-proof serviceability that increases rain.
Description of drawings
Fig. 1 is the compound nozzle structure schematic diagram of the present invention;
Among the figure, 1-jet pipe leading portion metal shell; The 2-plastic body; 3-larynx lining; 4-jet pipe back segment metal shell.
The specific embodiment
Below in conjunction with drawings and Examples content of the present invention is described further.
Embodiment
As shown in Figure 1, the compound jet pipe of a kind of hail-proof rain-increasing rocket of the present invention, this compound jet pipe comprise jet pipe leading portion metal shell 1, plastic body 2, larynx lining 3 and jet pipe back segment metal shell 4.
Plastic body 2 comprises jet pipe converging portion, throat and expansion segment by the compression moulding of plastics Integratively.Jet pipe leading portion metal shell 1 is embedded in the front end of plastic body 2, and jet pipe back segment metal shell 4 is embedded in the rear end of plastic body 2.To cover non-metallic inner liner fully different with metal shell in the prior art, and jet pipe leading portion metal shell 1 of the present invention and jet pipe back segment metal shell 4 be cover part plastic bodies 2 altogether.Inlaying between metal shell and the plastic body 2 adopts the compacting mosaic technology to realize.
The anti-anti-larynx lining 3 of ablating that washes away is inlayed by the throat of plastic body 2.Inlaying between larynx lining 3 and the plastic body 2 adopts technique for sticking to realize.Larynx lining 3 can adopt nonmetallic materials for example for graphite, also can adopt metal material.
When making,, can adopt compression tool that jet pipe front and rear sections metal shell and plastic body once are pressed into an integral body in order further to reduce operation.According to actual needs, the syndeton that processing needs on the section metal shell of front and back again is as screw thread etc.At last the larynx lining 3 with certain thermal protective performance is mounted to the throat of plastic body 2.
By above technical scheme as seen, the plastic body Integratively compression moulding among the present invention, and miscellaneous part is embedded on the plastic body, therefore can reduce the manufacturing procedure of compound jet pipe, shortens the process-cycle.And therefore metal shell part plastic covering body, and body do not adopt graphite reduces metal and anti-ly washes away anti-ablative nonmetal these raw-material consumptions, significantly improves its economy.
And just because of metal shell part plastic covering body, therefore reduced the use of metal material, and then obviously alleviated compound jet pipe weight, reduced the geometric eccentricity of compound jet pipe, improved its explosion-proof serviceability that increases rain.
