Embodiment 1
[0054] Figure 1 A flow chart flowchart of a solid-liquid rocket engine fuel rocket engine provided in the embodiment of the present invention.
[0055] Refer Figure 1 The method includes the following steps:
[0056] Step S101, obtain three-dimensional raw data;
[0057] Here, the acquisition of three-dimensional raw data mainly uses nuclear imaging techniques in industrial CT (Computer Tomography, computer fault). Due to the different scanning methods, the industrial CT is mainly divided into tapered ct, spiral CT, and sector CT, which is the most commonly used cone-beam CT. The scanning method of the cone CT is an open ray scan that uses a two-dimensional ray projection sequence of a flat panel to collect the entire tomographic image in the scanning area by three-dimensional rapidly reconstructing the entire tomographic image of the scanning area. The cone CT system includes an X-ray source, turntable and detector.
[0058]Specific detection process is as follows: Open industri...

[0083] figure 2 A solid-liquid rocket engine burning rate measuring apparatus according to a second schematic embodiment of the invention.
[0084] Refer figure 2 The device includes:
[0085] Acquisition unit 111 for acquiring the three-dimensional raw data;
[0086] Reconstruction unit 112 for reconstructing a three-dimensional original data to obtain a three-dimensional image of each slice layer;
[0087] Determination unit 113, to determine the length of each layer of the three-dimensional slice image according to a preset nominal value;
[0088] Thickness computing unit 114, according to the length of each layer of the three-dimensional image is cut, the grain is calculated after the engine test the axial thickness of the solid fuel;
[0089] Burning rate computing unit 115, an axial thickness of the solid fuel grain in accordance with the engine test, burning rate is calculated hybrid rocket engines.
[0090] Further, the reconstruction unit 112 is specifically configured t...
Embodiment 3
[0100] Figure 3 One kind of hybrid rocket engine burning rate measurement system according to a third embodiment of the present invention, a schematic diagram, Figure 4 Another solid-liquid rocket engine burning rate measurement system schematic according to a third embodiment of the present invention.
[0101] Refer Figure 3 Sum Figure 4 The system comprises a base 1, a vertical adapter plate 2, the triangular support frame 3, the thrust chamber simulation member body portion 4, an analog head part 5, a swing arm skid rails 6, rotary holder 7, CT probe 8, the probe 9 and a cylindrical support frame 10.
[0102] The system can grains 360 degree scan, CT probe 8 when the X-ray emission, the scanning detector 9 after receiving X-rays, and a plurality of three-dimensional raw data obtained from the attenuation results, by rotating the rotary holder 7, so that CT scanning probe 8 to 360 degree of grain.
[0103] Refer to Figure 5 Rotary support rail structure diagram recess portion 1...
