Problems solved by technology

[0003] With the continuous enhancement of China's national defense strength and the increase of unstable factors in the surrounding environment, design units and the military urgently need to establish test systems and methods for the low vulnerability and insensitivity of solid rocket motors. There is no test system for solid rocket motors. For this reason, this method has established a test system suitable for slow cook-off of solid rocket motors. After many tests and verifications, the results show that the device is stable in use, easy to operate, and the test results are consistent with The results of foreign countries are more consistent

Embodiment 1

[0027] see figure 1 , a solid rocket motor slow cook-off test system of the present invention, comprising a test chamber 1, a heating system 2, a control system, a data acquisition system, a video monitoring system, a shock wave overpressure sensor and a result discrimination system;

[0028] The test box includes two semi-cylindrical bodies, the two semi-cylindrical bodies are connected into a cylindrical body by buckles, the test box is provided with a sample support 7, and the top of the test box is inserted into a thermocouple 5, The thermocouple is connected with the data acquisition system through a signal line;

[0029] The heating system is wound on the outside of the test box, the heating system is connected to the control system through a control cable 6, the outside of the heating system is wrapped with thermal insulation cotton 3, and a protective shell is arranged on the outside of the thermal insulation cotton 4;

[0030] The control system adopts PID adjustmen...

Embodiment 2

[0042] The present invention will be described in further detail below taking the tactical engine of φ 315mm * 2100mm as an example, but the present invention is not limited to this example.

[0043] First, open the test chamber and insert the thermocouple into the top of the test chamber to the designed depth. Wrap the heating system with ceramic insulating blocks around the test chamber and fix it, and wrap the pre-made insulation cotton evenly on the surface of the heating system.

[0044] Secondly, connect the signal line and the heating system control cable, and remotely check whether the signal and heating system are normal through the control system. After checking the normality, place the tactical engine on the wooden support in the test box and fix it firmly with metal straps. Close the chamber and close the snap.

[0045] Furthermore, set a heating rate of 3.3°C / h, set the end temperature to 300°C, press the start button, and the data acquisition system, heating sys...

Abstract

The invention relates to a slow baking and burning test system of a solid rocket engine. The system comprises a test box, a heating system, a control system, a data acquisition system, a video monitoring system, a shock wave overpressure sensor and a result judging system, wherein the test box is connected with the two half cylinders through fasteners, a sample support is arranged in the test box,a thermocouple is inserted into the top of the test box, the thermocouple is connected with the data acquisition system, the heating system winds the outer side of the test box, the heating system isconnected with the control system, and the outer side of the heating system is sequentially wrapped with heat preservation cotton and a protection shell; and PID is adopted to adjust by the control system, the data acquisition system records the temperature inside the test box through a high-speed acquisition card, the video monitoring system records the damage degree of the test box, the shock wave overpressure sensor is used for recording the magnitude of the overpressure of the shock wave, and the result judging system is used for judging according to the damage degree of the test box andthe overpressure of the shock wave. The system provides data for evaluating and identifying the low-vulnerability and passive characteristics of the solid rocket engine.

Description

technical field [0001] The invention relates to a solid rocket motor slow cook-off test system, which can provide data for the design, development, evaluation and identification of parameters such as low vulnerability and insensitivity characteristics of the solid rocket motor. Background technique [0002] In modern warfare, fighter planes, ships, aircraft carriers and other combat platforms are equipped with various types of weapons. In order to improve combat capabilities, the energy and power of weapon models are getting higher and higher, followed by the deterioration of safety performance, especially in transportation Combustion or explosion accidents caused by external stimuli such as accidental falls, fires, etc. in the process of lifting, hoisting and combat will not only cause damage to one's own weapons and equipment, but also cause a large number of casualties and huge economic losses. For example, in April 1967, the USS Forrestal aircraft carrier caught fire and...
