[0027] Reference Figure 1-Figure 3 This utility model provides a test bench for various types of micro turbojet engines, comprising:

[0028] Supporting Platform 1;

[0029] A pair of optical bar slide rails 2 are set on the support platform 1, and a slider 3 is slidably connected on the optical bar slide rails 2;

[0030] The connecting frame 4 is connected to a pair of sliders 3. A pair of mounting plates 5 are provided on the connecting frame 4. Multiple mounting holes 6 are provided on the mounting plates 5. The spacing between the multiple mounting holes 6 and the diameter of the multiple mounting holes 6 are different. The mounting holes 6 are used to connect with a micro turbojet engine.

[0031] The push-pull force sensor 7 is mounted on the support platform 1, and the working end of the push-pull force sensor 7 is connected to the connecting frame 4.

[0032] By mounting the micro turbojet engine onto the mounting hole 6, during testing, the micro turbojet engine pushes the connecting frame 4 and the slider 3 along the optical bar slide rail 2. Data is collected by the push-pull force sensor 7 to realize the thrust test of the micro turbojet engine. Furthermore, a pair of mounting plates 5 are each provided with multiple mounting holes 6, and the spacing and diameter of the mounting holes 6 are different, which can be used to assemble different models of micro turbojet engines. This makes the test bench adaptable to the testing of different models of micro turbojet engines, thus improving the utilization rate of the test bench.

[0033] Furthermore, the sliding cooperation between the light bar slide rail 2 and the slider 3 allows the connecting frame 4 to slide smoothly without jamming.

[0034] The design was further optimized so that assembly hole 6 is a threaded hole, and the micro turbojet engine is connected to the threaded hole by bolts.

[0035] The design is further optimized so that the connecting frame 4 includes a base plate and side plates fixedly connected to both ends of the base plate. A mounting plate 5 is provided at the top of the side plate, and the base plate is fixedly connected to the slider 3.

[0036] Mounting plate 5 transmits force to the side plate, and then from the side plate to the bottom plate. The space between the two side plates is designed to accommodate a micro turbojet engine.

[0037] The scheme is further optimized by fixing a first fixing block 8 at each end of the light bar slide rail 2. The first fixing block 8 is fixedly connected to the support platform 1 and is used to raise and fix the light bar slide rail 2.

[0038] In a further optimized design, a second fixing block 9 is fixedly connected to the push-pull force sensor 7. The second fixing block 9 is fixedly connected to the support platform 1 and is used to fix the push-pull force sensor 7.

[0039] The design has been further optimized by installing anti-collision pads 10 at both ends of the light bar slide rail 2 to prevent damage to the slider 3.

[0040] The design was further optimized by adding multiple support legs 11 to the bottom of the support platform 1, thereby improving the stability of the support platform 1.

[0041] The design is further optimized by providing a through hole 12 at the bottom of the support leg 11 for mounting ground nails, which further improves the stability of the support platform 1 and enhances the stress resistance of the support platform 1.

[0042] Further optimization of the scheme also includes an oil pump 13, which is mounted on the support platform 1 and is used to connect with the micro turbojet engine to drive the micro turbojet engine to operate, so that the micro turbojet engine can receive good lubrication and fuel supply.

[0043] Further optimization of the scheme also includes a digital display mechanism, which is connected to the push-pull force sensor 7. The digital display mechanism is a display table or a weighbridge head, used to display the data collected by the push-pull force sensor 7.

[0044] Further optimization of the scheme also includes an electronic controller 14, which is used to connect to the push-pull force sensor 7 and the oil pump 13.
