It will boomerang back in weightlessness?
ISS - yes, in space - net
On Earth, the boomerang, as if by magic, back to throw it to the man. More precisely, the magic has nothing to do with it - it is the laws of aerodynamics. But it will boomerang as to behave in weightlessness? Astronaut Takao Doi decided to check it out and threw a boomerang at the International Space Station. And boomerang back to it - over and over again. While the ISS is almost no gravity, the air breathed by astronauts, allows boomerang behave in weightlessness as well as on Earth.
Boomerang asymmetrical sides, one side is slightly curved, and the second - straight, with curved side communicates with air more. With this design, and the boomerang returns: upper blade roll rotates faster at the bottom, and the higher the boomerang rises, the more it affects the aerodynamic force. With this same force is gradually reduced, and the boomerang returns to the owner.
And all this can work in the absence of gravity.
But what if you throw a boomerang in space? In space there is no air, so that the boomerang will not do anything at all - neither fly nor to return, or even slow down, it just will float through space, just like any other piece of cloth.
But apart from the aerodynamics, there are other forces that may come into play. If you throw a boomerang precisely at a right angle, then theoretically it could accelerate to a speed sufficient to overcome the Earth's gravity and fly into orbit, where he joined the swarms of space debris, and with them will circle around the planet.
