TDean Posted November 29, 2004 Share Posted November 29, 2004 You're all forgetting a variable here. Anyone know how satellites stay in orbit? They are actually being pulled towards earth as they scream across space, but the curvature of the planet and the speed of the satellite keeps the altitude the same. The bullet would stay in flight longer because the earth will curve away from the plane of the shot slightly, whilst the brass stays in pretty much the same geographical spot. he-he..

MikeFoley Posted November 30, 2004 Share Posted November 30, 2004 TDean, I wonder if we can get a round into orbit? Maybe a international contest for getting a round into orbit. The round continues to fly, but the brass is on the ground next to my... Link to comment Share on other sites More sharing options...

Seeing that a satellite travels around 24000 MPH, for a geostationary satellite at a altitude of 22,300 miles, and the fastest bullet, from a rifle or any other barreled firearm, travels at the most 2700+ MPH. That is almost 9 times less than what the SAT does and the BIG reason the SAT stays up is it is ALMOST OUT of the pull of earth gravity. So your variable doesn't even come into play.

Scooter Posted December 1, 2004 Share Posted December 1, 2004 TDean,I wonder if we can get a round into orbit? Maybe a international contest for getting a round into orbit. The round continues to fly, but the brass is on the ground next to my... The big problem is air resistance and lack of propulsion after the bullet leaves the barrel. Because of air resistance, the bullet is slowing down when it leaves the barrel. Under an ideal situation of no air resistance, it is theoritically possible. Assuming there is no air, a bullet leaving the barrel at say 4000 fps being slowed only by gravity will reach 0 fps in 124.2 seconds. This translates to 745232.8 feet or 141.14 miles. X prize only required 100 km or 62.5 miles. You would need an insanely high initial velocity if you factor in air resistance. Link to comment Share on other sites More sharing options...
mcoliver Posted December 1, 2004 Share Posted December 1, 2004 As an experiment, haven't they tried shooting a gun on the moon yet? Or does one need a very special permit to transport firearms to the moon? Link to comment Share on other sites More sharing options...
MikeFoley Posted December 1, 2004 Share Posted December 1, 2004 Scooter, we're going to need more powder and a larger case volume. MColiver, I'm sure Kentucky Concealed Carry permits have reciprocity on the moon. Link to comment Share on other sites More sharing options...
Scooter Posted December 2, 2004 Share Posted December 2, 2004 If you fire a gun on the moon, the bullet will have a much higher ballistic coeffiecient and it'll drop 1/6 less than on earth. If you have sufficient velocity, you might happen to shoot yourself in the back. Link to comment Share on other sites More sharing options...
