Embodiment Construction
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0042] Such as figure 1 As shown, the laboratory high-temperature aging test system for gel-state cloud explosion agent provided by the present invention includes a sealed tank, an open high-temperature aging system, a fiber grating sensing system, and the like. according to figure 2 , The sealed tank mainly includes components such as a glass reactor 1, a tank body 2, a cover 6, a fixing nut 8, and a sealing ring 4. The tank body 2 is a cylinder with no seal on the top, and an outer fixing ring protruding outwards on the outer ring of the upper end, and 6 through holes 3 for fixing are equidistantly distributed on the outer fixing ring, and the inner edge of the upper end of the tank body is 7 more than the outer edge. The upper end face of the fixed ring is 3mm lower. The glass reactor 1 is an unsealed cylinder whose outer diam...

Abstract
The invention discloses a lab high-temperature aging experiment system for gel state composite fuel, comprising a sealing tank, an opening type high-temperature aging system, and an optical fiber grid sensing system. The gel state composite fuel is placed in a sealing tank, a sensor of a fiber bragg grating is vertically embedded in the sample; an optical fiber end is connected with a demodulator, and the demodulator is connected with an industrial personal computer. The sealing tank is placed in the opening type high-temperature aging system to perform the aging test; the sensor collects the sample temperature and strain data in real time and draws up a monitoring curve, thus the temperature and strain change of the sample in the aging test can be observed. The system eliminates the explosive hidden trouble caused by heating and volatilizing isopropyl nitrate to air, and guarantees the safety of the thermal aging test of the el state composite fuel. The system monitors the temperature and strain change of the el state composite fuel aging sample in real time for the first time, and solves the problem that the sample information cannot be acquired timely for explosives and powders are under a 'black box' model in aging test. The invention is further used for the estimation of service life of the gel state composite fuel, and so on.
Description
technical field [0001] The invention belongs to the field of performance testing and research of energetic materials, and mainly relates to the high-temperature aging test of the gel-state cloud-explosive agent, especially the monitoring of the aging state of the gel-state cloud-explosive agent in the high-temperature aging test. Background technique [0002] Weapons and equipment must be able to ensure safe storage and reliable use under various environmental conditions. If the environmental adaptability is poor, it may cause huge safety hazards and economic losses. [0003] The storage, transportation and use status of any weapon equipment during its life will be affected individually, combined and comprehensively by various climatic environments and mechanical environments. These effects will inevitably corrode or damage the materials and structures of weapons and equipment, degrade the performance and malfunction of components, equipment and electronic devices, thereby a...
