The enthusiast proposes to solve the problem of planting through the use of various fibers, Kevlar, carbon, flexabit, UHWPE, ONNEX. The best option the author considers the use of heavy-duty and high-modul fibers (threads) of high-molecular polyethylene. Of course, ropes made of polyethylene should be protected by a special heat-resistant shell so as not to burn from the torch of the engines.
The insulation shell made of ceramic wool will serve as an additional buffer in contact with the rocket body. According to the author, he doubts that musk's mechanical arm will be able to more delicately grasp the rocket without damage. The mechanical arm of MECHAZILLA in the idea of SpaceX should make the girth of the rocket with greater accuracy of landing than the proposed technology semenov.
When working hands, the permissible deviations do not exceed 1 meter! The hand drive is powered by a single engine, and a mistake of a few meters can be fatal. And there is a problem with the great inertia of the entire structure, the ship will not be able to stand on its own supports and slowly reduce the speed to zero on them, most likely functionally this is not a trap, but an active platform at a height. They do not catch it, but give the ship the only chance that he himself could land on it.
All these shortcomings gave reason to think the author about a simpler solution...
An alternative option is an area of 500x500 meters, allowing the rocket to deflect up to 10 degrees! The trap actively accepts the missile without relying on the maneuvering of the missile itself. According to the author of the idea, the system will cost no more than one missile, but will last for decades. The system is essentially a huge station with the kinematics of a parallel robot, which was patented. This gives a gain in reliability, carrying capacity and allows you to use the system in different weather conditions. As the engineer Dahir Semenov specified, "Firstly, our ropes are able to actively escape from the torch of the engines during the passage of the ship through the trap window, and secondly, there are heat-resistant ceramic fabrics that hold high temperatures well and are not so easy to burn. I'm calm about this. In the carrying capacity of ropes, we are not limited at all, now there are fibers stronger than steel 15 times, it costs nothing to create special ropes for 1000 tons with a heat-resistant shell. "
One of the side advantages of using the system, according to the author, will be the absence of the need for retractable supports on the rocket, which will reduce the overall weight of the missiles. Braking of the missile trapped will be carried out hydraulically. Dampers of special design will provide the minimum reverse acceleration that is possible mathematically at a given speed and braking distance.
The new trap system is replaceable, it has a dozen different tools for different occasions, can change them ten times a day and take ten different ships. It is potentially possible to launch from the same stations of "soft landing".
