Abstract

The invention discloses a low-gravity-field aircraft impact experiment system and experiment method. A tower, a lifting unit, an experiment cabin unit, an impact buffering unit, a water well and a measurement and control unit are arranged, buoyancy generated when a buoyancy container enters the water well is utilized, the total resultant force of the experiment units is reduced, and the experiment requirement for simulating the low-gravity-field environment is met; by changing the volume or weight of the buoyancy container, experiment requirements of different environments of a 0-1G low gravity field are met; the buffering force of the buffering unit can be adjusted to achieve different buffering effects, the experiment module and the buffering unit are bounced while the buffering force is generated after the experiment module makes contact with the buffering unit, and it is guaranteed that a low gravity field is constant. The experimental system is simple in structure, the experimental method is simple in step and easy to operate, research data is provided for landing impact of the aerospace craft, and a guarantee is provided for further exploration of unknown planets.

Description

technical field [0001] The invention relates to an aircraft impact experiment system and an experiment method in a low gravity field, and belongs to the technical field of simulated gravity field experiments. Background technique [0002] In the process of manned spaceflight exploration of unknown alien planets, when the aircraft lands, the research on the impact force index of the alien planet's gravity field on the human body is an important topic to ensure the safety of people and objects in the aerospace process. [0003] At present, the experimental equipment for high G (G is the acceleration of gravity of the earth) value acceleration at home and abroad is relatively complete, including experimental devices such as rocket pulley, rotating seat, shock wave wind tunnel and shock tower. Among them, the rocket block uses solid rockets or rocket launchers as the power source, and its acceleration value can reach 40-50G; the shock tower can also reach an acceleration of abou...
