Mars dust collecting device in hypervelocity flight state and application method thereof

Abstract

The invention discloses a Mars dust collecting device in the hypervelocity flight state. The Mars dust collecting device comprises a dust particle collecting port, a gas inlet pipe, a filtering and collecting device, an exhaust pipe and a returner, wherein the filtering and collecting device is installed in the returner; the returner is installed inside a detector; the gas inlet pipe and exhaust pipe respectively penetrate through the returner and are connected with the filtering and collecting device; the dust particle collecting port and exhaust pipe are connected with the outer side of the detector; the dust particle collecting port is connected with the front end of the gas inlet pipe; the gas inlet pipe is connected with a filtering inlet of the filtering and collecting device; and a filtering outlet of the filtering and collecting device is connected with the exhaust pipe. The Mars dust collecting device can implement filter-type fine dust sampling in the Mars atmosphere in the hypervelocity flight state, avoids the links of landing-descending and Mars surface rising in the traditional sampling return process, reduces the detector weight and task complexity, and thus, has engineering application value. The Mars dust collecting device has favorable expandability, and lays the foundation for other subsequent planet sampling detection and development in China.

Description

Technical field [0001] The invention relates to the technical field of particle collection for Mars sampling and return detection missions, in particular to a Martian dust collection device under ultra-high-speed flight conditions and a use method thereof. Background technique [0002] Compared to the Earth’s atmosphere, the Martian atmosphere is very thin, but it contains a lot of dust. Because the surface of Mars is windy all the year round, frequent dust storms will blow the soil particles on the surface of Mars into the air. According to observations, soil particles will rise to a height of 60km during a dust storm, so Martian soil can be collected in the air. [0003] The prerequisite for the completion of sample collection in traditional Mars sampling and exploration missions is to ensure the successful landing of the probe, the normal deployment of the mechanical arm structure during the sample collection process, and the safe ascent and return of the returner; the whole pr...

Problems solved by technology

[0003] The premise of the traditional Mars sampling exploration mission to complete the sample collection is to ensure the successful landing of the probe, the normal deployment of the mechanical arm structure during the sample collection process, and the safe ascent and return of the returner; the whole process is cumbersome and complicated, and the risk is high

Since the mechanical arm generally adopts drilling and sampling, it has many degrees of freedom and is not easy to manipulate, and requires high structural strength, which increases the structural weight of the whole device.
