[0032] How it works

[0033] The vehicle body 1 moves to the target area, and the front probe 6-4 of the front detection unit 6 located at the front end of the vehicle body 1 drills into three points on the lunar soil surface and three to five lunar soil surfaces in the sintering area to perform performance tests and obtain initial lunar soil performance data.

The scattered microwaves generated by the excitation of the microwave source 4-1 are directedly conducted to the reflective inner cavity 4-3 through the waveguide 4-2, and the sintered lunar soil absorbs the microwaves; the absorption of microwave energy causes the molecules to move violently, resulting in a macroscopic increase in the temperature of the lunar soil to reach partial melting, and then cementation and hardening;

[0034] After the sintered part is cooled, the rear detection unit 11 is used to press the sintered surface to obtain physical parameters such as sintered hardness and strength parameters;

[0035] Sintering and performance testing are carried out at intervals, with a total sintering time of five to eight hours. Performance tests are carried out at three points after every hour of sintering to obtain data on changes in the strength properties of the sintered lunar soil.

[0036] The collected data is transmitted to the ground through the integrated control system 8, the sampling data is analyzed and calculated, and the ground control signal makes a decision on the sintering trolley.
