Abstract

The invention relates to the technical field of space environment detection, and in particular, relates to a multifunctional space high-speed dust characteristic detector comprising a box body, a charge induction grid mesh, a flight time mass spectrometer, a microscopic camera, a dust collection device and a dust impact target, wherein a charge induction grid mesh, a time-of-flight mass spectrometer and a dust impact target are sequentially arranged on one side in the box body from top to bottom; and the microscopic camera and the dust collection device are arranged on the other side of the box body, and the microscopic camera is arranged above the dust collection device. According to the invention, in-situ comprehensive detection of interplanetary high-speed dust charge, speed, particle size and components is realized, the system integration degree is high, the functions are comprehensive, the detection precision is high, the number of measurement parameters is large, and a plurality of important characteristics and comprehensive detection data of interplanetary dust can be obtained.

Description

technical field [0001] The present application relates to the technical field of space environment detection, in particular to a multi-functional space high-speed dust characteristic detector. Background technique [0002] In the future, our country will carry out a series of deep space exploration missions. These missions will involve the detection of the characteristics of interplanetary dust in the solar system. The speed of interplanetary dust is generally in the range of 1km / s to 70km / s, which belongs to high-speed dust. Most of the particle sizes are in the micron range. The comprehensive detection and research of dust characteristics, using sensors to obtain in-situ measurement data, can answer a series of major scientific questions, such as the formation and evolution of the solar system, the source of water on the earth, etc., and at the same time can obtain space dust The impact data of deep space probes can solve engineering problems in the implementation of missi...
