Abstract
The disclosure discloses a penetrating cushion damping device comprising a penetrator, and belongs to the field of in-situ penetrating exploration of extraterrestrial celestial bodies. A magnetic conductor encloses the non-penetrating end of the penetrator, a drag plate connected to the penetrator is provided at the lower end face of the magnetic conductor, and a magnetic source structure for generating magnetic force on the magnetic conductor is provided in the non-penetrating end of the penetrator. The disclosure utilizes the penetrating cushion anti-drag mode with the drag plate and the electromagnetic structure, which is self-adaptive to the flight penetration speed and compact in structure, reduces the jump probability, and further reduces the cushion resistance after the speed is reduced. This mode is suitable for the kinetic energy penetration exploration of extraterrestrial celestial bodies with unknown terrain conditions, and takes into account the functional requirements of penetration depth and star surface retention.
