Rocket recycling device with retracting device

Abstract

A rocket recovery device with a retractable device, which relates to the field of aerospace equipment recovery, including a platform, a funnel device and a retractable device; the funnel device is in the shape of a funnel and is installed under the platform, and the funnel device is embedded in the platform; the retractable device is installed on the rocket The middle or upper part; the funnel channel is installed under the funnel device, which is in the shape of a funnel when it is opened, and its size is basically consistent with the funnel device. The retractable device is in a retracted state when the rocket takes off, sticking to the rocket, and the rocket flies back to the sky above the platform , and then the retractable device is opened to form a funnel structure, the rocket lands, and the position of the rocket is slowly calibrated to the center of the funnel device until the end of the retractable device contacts the end of the funnel device, and the rocket lands smoothly. 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 rocket recovery device with a retractable device relates to the field of aerospace equipment 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: 1. 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 ...

AI Technical Summary

Problems solved by technology

Some recovery methods at this stage are: one is 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 process of the invention are too complicated and difficult to control
