[0032] The rotation system is used to drive the space capsule 3 to rotate circumferentially on the annular double helical track 11;

[0033] The in-cabin computer 4 is used to control the thrust of the rotation system and thus control the speed of the space capsule 3 moving in the double helix track 11 .

[0034] The space capsule 3 is used to accommodate simulated test personnel and is rigidly connected to the space capsule outer arm 5 .

[0035] The space capsule 3, the space capsule outer arm 5, the rotation system and the cabin computer 4 together constitute Figure 2 The environmental simulation system shown in Figure 2 for Figure 1 A partial enlarged view of the structure of the environmental simulation system shown in A in the middle, where experimenters experience the hypergravity environment and conduct simulation experiments.

[0036] The use of a circular double helix track structure enables the space capsule to simultaneously experience a hypergravity environment and a self-rotating environment, compared to previous aerospace test equipment that could only achieve a single type of movement, providing a good method for simulating the re-entry process; the device has a simple structure, is easy to control, occupies a small space, and can simultaneously place multiple environmental simulation systems on the circular double helix track, realizing simultaneous simulation of multiple astronauts and making efficient use of time and space.

[0037] Preferably, two space capsule outer arms 5 are provided, and the two space capsule outer arms 5 are symmetrically arranged on both sides of the space capsule 3 .

[0039] The rotating system comprises: a guide plate 8, a guide wheel 1, an air jet assembly 2 and a rotating shaft assembly;

[0040] One end of the rotating shaft assembly is connected to the outer arm 5 of the space capsule, and the other end of the rotating assembly is connected to the guide plate 8.

[0048] Preferably, the jet assembly 2 is provided in one or more groups, and the one or more groups of the jet assembly 2 are connected to the guide plate 8 at intervals.

[0049] The jet assembly 2 is arranged on the left and right sides of the guide plate 8 in one or more different positions.

[0050] The jet assembly 2 determines the jet amount according to the position of the guide wheel 1, thereby controlling the forward speed of the guide wheel 1 along the annular double helical track 11. The purpose is to ensure that both guide wheels are in a radial plane with the annular double helical track 11 as the center through the above operation.

[0051] Preferably, the space capsule 3 is also provided with an inlet and an outlet and a space capsule door 9 arranged corresponding to the inlet and outlet, and the space capsule door 9 seals the space capsule 3 when the environmental simulation starts.

[0055] Preferably, a plurality of groups of the annular double helical track mounting and fixing rods 10 are arranged in parallel, and the plurality of groups of the annular double helical track mounting and fixing rods 10 vertically mount the annular double helical track 11 in a vertical plane.

[0056] The parallel installation of multiple sets of annular double helical track mounting fixing rods 10 can further stabilize the annular double helical track 11, thereby performing multiple sets of tests and increasing the safety of the device.

[0057] Embodiment 2:

[0058] A method for using a ring-shaped double-helix orbital device for realizing a supergravity rotating environment, such as Figure 5 As shown, including:

[0059] When the rotation system is started, the computer 4 in the cabin controls the magnitude of the thrust provided by the rotation system, and the rotation system drives the space capsule 3 to rotate axially on the circular double helical track 11 through the space capsule outer arm 5;

[0060] When the rotation system is turned off, the computer 4 in the cabin controls the rotation system to stop providing thrust, and the space capsule 3 decelerates under the action of gravity and friction, and falls back to the bottom of the circular double helical track 11;

[0061] Among them, the annular double-helix orbit type device for realizing a supergravity rotating environment is the annular double-helix orbit type device for realizing a supergravity rotating environment as described above.

[0062] The test simulation personnel enter the space capsule through the hatch 9, and then start the cabin computer 4, and then the jet device 2 is started, driving the guide plate 8 and the guide wheel 1, and the guide wheel 1 moves forward along the circular double helical track, and then the environmental simulation system composed of the space capsule 3, the guide wheel 1, the guide plate 8, the jet device 2, the cabin computer 4, and the space capsule outer arm 5 moves forward, and the center part, i.e., the space capsule and the space capsule outer arm 5, moves in a circumferential direction with the circular double helical track 11 as the center, as shown in FIG. Figure 1 Shown is clockwise direction.

[0063] The kinematic environment of the test simulator in the space capsule 3 is centrifugal motion around the center of the circular double helix track 11 and rotational motion around the space capsule itself in a radial plane formed by the two guide wheels 1 and the center of the circular double helix track 11.

[0064] The composite motion environment of this device is used to simulate the complex motion environment in which astronauts experience both hypergravity and self-rotation during the space flight process.

[0065] At the end of the test, the computer 4 in the cabin is turned off, and then the jet device 2 stops jetting. The environmental simulation system loses its power source and gradually slows down under the action of gravity and friction, and finally falls back to the bottom of the circular double helix track, which is the position closest to the ground.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application rather than to limit its protection scope. Although the present application has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the present application, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the application, but these changes, modifications or equivalent substitutions are all within the protection scope of the claims to be approved.
