Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as Figure 1-2 As shown, a high-altitude fire extinguishing rocket composite material launching tube prepared by the manufacturing method of the present invention includes two metal liners 1 and a composite material cylinder 2 . The metal liner 1 has an annular step 6 and at least one annular protrusion 7 in sequence, and the annular step 6 has rounded corners. The two ends of the composite material cylinder 2 are respectively sealed and connected to a metal liner 1, the annular step 6 and the annular protrusion 7 of the metal liner 1 are installed in the composite material cylinder 2, and the metal liner 1 An annular step 6 is located at the end of the composite barrel 2 .

[0034] Such as image 3 As shown, the composite material barrel 2 includes a heat-resistant anti-scour coating 8 in the inner layer, a sealing layer 9 in the middle layer and a bear...

Abstract

The invention relates to a manufacture method for a composite-material launch canister of a high-altitude fire-extinguishing rocket. The launch canister comprises two metal bushings (1) and a composite-material canister body (2), and each of the two ends of the composite-material canister body (2) is hermetically connected with one metal bushing (1). The manufacture method is characterized by comprising the following steps: 1) making a cylindrical mould with smooth surface according to the structure of the launch canister inner chamber; ... 10) machining the external diameters of the canister body and a reinforcement hoop prepared in the 1)-9) steps. The prepared composite-material launch canister of the high-altitude fire-extinguishing rocket by employing the manufacture method of the invention has light weight, strong bearing capability, high-temperature flame sweep resistance, high pressure resistance, good seal performance, strong corrosion resistance, multi-time reuse and low maintenance cost.

Description

technical field [0001] The invention relates to a manufacturing method of a multifunctional composite material launcher, in particular to a manufacturing method of a high-altitude fire-extinguishing rocket composite material launcher. Background technique [0002] In recent years, with the acceleration of my country's urbanization process, high-rise and super high-rise buildings are increasing day by day. High-rise buildings have a lot of combustibles inside, a lot of electrical equipment, and criss-crossed electrical lines, which are very prone to fire, and the fire has the characteristics of great destructive power, great difficulty in fighting and fire, and many ways of fire spread. When a fire breaks out in a high-rise building, it is extremely difficult to evacuate and fight the fire, and it is very easy to cause serious consequences of mass death and mass injury. The research and application of high-altitude fire-fighting and rescue technology in my country is relativ...
