Modular separable survivable impactor based on hierarchical protection

Abstract

The invention provides a modular separation type survivable impactor based on graded protection. The separation idea is that a propelling module, a high-integration control module and a connecting andseparating module do not adopt protection, are separated from a body structure and a high-reinforcement control module before impact and do not survive after impact. According to the grading idea, three-level protection is adopted for electronic equipment in the high-reinforcement control module, the first-grade protection is of a body structure and is made of a high-strength material, the deformation after impact is reduced as much as possible, and the inner high-reinforcement control module is prevented from being extruded; the second-grade protection is a high-reinforcement control module,the appearance is made of a high-strength material, a buffer sub-module is arranged in the second-grade protection, and impact energy is absorbed through a buffer structure while deformation is avoided after impact; and the third-grade protection is a potting sub-module and electronic equipment in the high-reinforcement control module, and epoxy resin is adopted for potting the internal electronic equipment, so that the impact resistance of the electronic equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of deep space exploration aircraft, in particular to a modular detachable survivable impactor based on hierarchical protection. Background technique [0002] With the development and progress of space technology, the means of deep space exploration have developed from the initial overflight detection to multi-modal combined detection such as orbiting, landing, inspection, and sampling, realizing the leap from orbiting to landing, from the surface to the interior, and are moving towards three-dimensional detection, Internal depth detection direction development. Impact detection is an efficient means to achieve internal detection. It has the characteristics of simple and reliable structure, high integration, and flexible configuration. It can penetrate into the interior of celestial bodies with less resource consumption. [0003] A traditional striking head as disclosed in patent document 103743637A ...

Problems solved by technology

[0004] However, the traditional impactor is mostly used in biomedicine, fire protection and other fields, mainly through impact to achieve crushing, actuation and other actions. The impactor itself does not have a circuit or survival function
