Note that the G 1 model bears little resemblance to modern projectiles. Do you think that a modern bullet has the same aerodynamic properties as the G 1 model? All dimensions given in calibers. is believed to be accurate. If you have further. Sporting bullets, with a calibre d ranging from 4.4 to 12.7 millimetres (0.172 to 0.50 in), have C b in the range 0.12 lb/in 2 to slightly over 1.00 lb/in 2 (84 kg/m 2 to 703 kg/m 2). Those bullets with the higher BCs are the most aerodynamic, and those with low BCs are the least. Visa mer In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative … Visa mer Background In 1537, Niccolò Tartaglia performed test firing to determine the maximum angle and range for a Visa mer Satellites in low Earth orbit (LEO) with high ballistic coefficients experience smaller perturbations to their orbits due to atmospheric drag. The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior.
