Embodiment Construction

[0030] Such as figure 1 and figure 2 As shown, it is described that the umbrella canopy 60 has been opened to form a resistance surface to decelerate the spacecraft when entering orbit; while the first airbag 30 and the second airbag 40 are in a retracted state. Among the figure, there are 12 traction ropes 50 in total, one end of each traction rope 50 is tied to the edge of the canopy 60 , and the other end is tied to the base 20 , and the resistance formed by the canopy 60 is transmitted to the base 20 . The base 20 carries the first airbag 30, the first gas generator, the second airbag 40, the second gas generator, and the landing module 10; the first airbag 30 and the second airbag 40 sandwich the landing module 10, and the first airbag 30 below and the second airbag 40 above. The first airbag 30 is connected with a first guide collar 32 with each traction rope 50, and the first guide collar 32 can slide up and down along the traction rope 50; the second airbag 40 and e...

Abstract

The invention relates to the technical field of aerospace, and relates to a reducer capable of buffering landing. The technical problem that existing deceleration technology is insufficient is solved.According to the technical scheme, after a lander reaches a predetermined height, a deceleration umbrella is wrapped around the outer surface of an air bag so as to protect and enhance the air bag. The technical measure comprises a canopy, a traction rope, a base, a first air bag, a first air generator, a second air bag, a second air generator and a landing cabin. The first air bag is of a closedair bag-like structure, and is capable of expanded through inflating, the lower end of the first air bag is fixedly connected with the base, and the upper end of the first air bag is fixedly connected with the landing cabin. The second air bag is of a closed air bag-like structure, and is capable of expanded through inflating, and the lower end of the second air bag is fixedly connected with thelanding cabin. When the first air bag and the second air bag are inflated and expanded, the landing cabin is clamped between the air bags. The reducer has the beneficial effects that when the landingcabin lands, the canopy and the traction rope are wrapped around the outer peripheries of the first air bag and the second air bag, the strength of the first air bag and the strength of the second airbag are enhanced, and then the protection of the landing cabin is enhanced.

Description

technical field [0001] The invention relates to the field of aerospace technology, and relates to a reducer capable of cushioning landing. Background technique [0002] Spacecraft entry technology refers to the technology in which a spacecraft enters the atmosphere of an alien planet based on set requirements and then softly lands on the surface of the planet. It usually includes the following stages: 1. Departing from the orbit; 2. Transition into the transition period; 3. Entering the atmosphere; When entering the orbit, the spacecraft needs to be decelerated so that the spacecraft can land softly on the surface of the planet; among them, the existing deceleration parachute combined inflatable deceleration is a feasible technology; for example, the landing process of the Opportunity Mars rover in the United States is as follows: Fold it on the surface of the lander. When the lander reaches the predetermined height under the action of the drogue parachute and the braking e...
