Funnel-shaped rocket recovery device

Abstract

A funnel-shaped rocket recovery device, related to the field of aerospace equipment recovery, including a platform, a rocket, a funnel device and a stabilizing device; the funnel device is in the shape of a funnel, installed under the platform, and the funnel device is embedded in the platform; the stabilizing device is installed directly below the funnel device, The size of the stabilizer matches the size of the rocket. The rocket flies back to the sky above the rocket recovery device of the present invention, then aligns with the funnel device and lands. During the landing process, when the rocket is not aligned with the stabilizing device, the funnel device can also pass through the lower end of the rocket when it is in contact with the stabilizer. The structural advantage of the funnel shape slowly corrects the position of the rocket until the lower end of the rocket enters the stabilizer. The structure and principle of the present invention are very simple, and can be applied to sea and land, and the present invention also well solves the problem that the rocket is easy to fall and cause explosion during the early recovery process.

Description

technical field [0001] A funnel-shaped rocket recovery device relates to the field of space material recovery, in particular to a rocket recovery device. Background technique [0002] The launch vehicle is a space vehicle. The cost of the rocket engine is 60 million US dollars. The launch cost is 200,000 US dollars. At present, most of the launch vehicles are disposable space vehicles. After the first stage is separated, the rocket will fall to the uninhabited land or open sea , can not be reused, which increases the cost of aerospace research. [0003] If the first stage of the launch vehicle can be recovered at the moment of falling, the cost of aerospace research can be reduced. All countries are developing rocket recovery technology, but they all fail. Some recovery methods at this stage are parachute recovery. The empty arrow weighs 10 tons and lands upright. If it falls to the ground, it will be damaged twice. If it falls sideways, it will damage most of it. The seco...

Problems solved by technology

At present, some recovery methods are parachute recovery. The empty arrow weighs 10 tons and keeps landing upright. When it falls to the ground, it will be damaged twice. If it falls sideways, most of it will be damaged. If it falls into the sea, it will be completely damaged. The salvage is for confidentiality.

The second is that the rocket developed by the United States recently landed vertically and succeeded in land-based experiments. However, the earth rotates, and most of its area is the sea, so it must land on the sea. The platform fluctuates due to waves, which affects the flight attitude. Therefore, every sea experiment Every time when it hit the ground, it tilted and exploded

[0004] The invention patent with publication number CN105783610A can solve this problem to a certain extent, but the equipment and recycling process of the invention are too complicated and difficult to control
