In the US, proposed to use the principle of "sling" to launch missiles

Attempts to "reduce the cost" of missile launches push designers to implement, it would seem, the most incredible ideas. So, engineers from the American startup SpinLaunch have proposed a concept that allows you to send carriers with a payload on the sling principle to space.

In theory, an installation resembling a high-tech centrifuge can spin an object inside a vacuum chamber to a speed of 8000 km / h, and then “throw” it into the stratosphere through a special hole in the launch tunnel. After a rocket with a payload reaches a certain mark, the engine of the first stage will be connected to the process, which will ultimately bring the cargo into orbit.

The developers claim that their method will not only save fuel, but also bring the number of starts to 5 per day. According to SpinLaunch Director Jonathan Yani, sending a payload rocket through a “centrifuge” will cost the customer about $ 500. For comparison, the cost of launching carriers from SpaceX and Blue Origin today ranges from 5 to 100 million.

It is worth noting that promising development exists not only on paper. The company has already managed to conduct an experiment, during which an object weighing 5 kg was dispersed to 6400 km / h and “thrown” into a steel wall. At the same time, back in May last year, a facility was built in the state of New Mexico, which in the future will be used for full-scale tests. A month later, SpinLaunch signed a contract with the US Department of Defense.

    What a joy, the high-energy concept of Dmitry Rogozin "Trampoline" won among all available alternatives. I think that Canada and Mexico should prepare for the arrival of "space debris".

      Who do you call "space debris" here? I'm afraid even to suggest, really Dima?

    The idea is not as funny as it might seem. There is only one caveat. Overload at the moment of departure from the booster will be very high. So, not every payload can be removed and delivered in this way.

      ... a counterweight of the same mass for the remaining half-revolution will simply break the centrifuge and, at best, fly after the payload. At worst - in the direction you have to and take care of your head in the neighboring state.

    When throwing a rocket into the sky, there will be frantic overloads on the rocket ... plus the high temperature of the rocket surface .... They still can’t figure it out with hypersound ... And they have already pinned their ears into space!) The company wants money ...) That's it breed suckers from the government.
