Aerodynamic decelerator

Abstract

The invention relates to an aerodynamic decelerator which comprises a canopy and a plurality of dense momentum adjusting assemblies. The canopy comprises a top face and a side face. The dense momentum adjusting assemblies are evenly distributed on the top face and the side face of the canopy and comprise return locks, first wind plates, second wind plates, first elastic pieces, second elastic pieces and wind plate clamps. The design scheme of the aerodynamic decelerator capable of automatically adjusting the dense momentum is creatively provided. Compared with the prior art, the aerodynamic decelerator is based on the hydromechanical basic principle, and the aerodynamic decelerator has the automatic adjusting function on the dense momentum by means of the design of one-way air channels, the wind plates, the wind plate clamps, the return locks and the elastic pieces. A pair of acting force and counter acting force is formed by aerodynamic force formed by the wind plates and elastic force, provided by the elastic pieces, of the return locks, and the aerodynamic decelerator achieves the automatic adjusting function on the dense momentum by changing the included angle between the wind plates and the canopy.

Description

technical field [0001] The invention relates to the fields of aerospace and extreme sports safety, in particular to an aerodynamic speed reducer for automatic adjustment of close momentum. Background technique [0002] The aerodynamic reducer refers to the parachute. As a typical aerodynamic reducer, parachute is widely used in extreme sports and aerospace fields. According to written records, the first person to use a pneumatic reducer (bamboo hat) was Shun. Unlike Galileo's falling experiment on the Leaning Tower of Pisa, no Chinese have ever thought about the reason why Shun did not fall to his death. Fortunately, the world's largest Shenzhou spacecraft parachute is still made in China. The statement that "like gunpowder, parachutes also came from China" is well-documented. [0003] Although the existing parachutes vary greatly in shape and structure, they still cannot get rid of a problem: the larger the canopy, the greater the risk of the canopy breaking. On Earth,...

Problems solved by technology

[0003] Although the existing parachutes vary greatly in shape and structure, they have not been able to get rid of one problem: the larger the canopy, the greater the risk of the canopy breaking

For Mars, which has only 1% of the earth’s atmospheric density, the existing landing technology cannot exceed 1.5 tons of landing technology (to ensure the safety of launching instruments and equipment), which is restricting the Mars exploration mission that requires about 500 tons of materials, and requires a new landing method.

Although the space parachute was invented, the fact that the speed reducer was torn to shreds during its first test shows that many problems remain to be solved

In addition, as one of the milestones of aerospace technology, the space shuttle was abandoned. The essence is how to solve the problem of low-density supersonic speed. Due to the high temperature of high-speed flight, most of the instruments are damaged, and the single launch exceeds the budget by nearly ten times (the cost of a single launch cost about $450 million)
