Web13 de jun. de 2024 · That’s it. A “ballistic coefficient,” or “BC,” is a number assigned to a bullet that suggests its aerodynamic performance. That’s a key word, “suggests.”. The main suggestion is how well this bullet will fly compared to that bullet, and the one with the higher BC ought to fly better. Web27 de jan. de 2024 · The better ballistics Apps allow the user to select either G1 or G7 Ballistic Coefficient values to calculate the bullet’s flight path. The BC of a bullet is its ability to overcome air resistance during its flight. As you have probably seen G7 values are numerically lower around 50% lower than the G1 values for the same bullet.

WebLower ballistic coefficient offers an optimal re-entry, wherein the vehicle decelerates higher up in the atmosphere thereby decreasing the imposed aerothermal loads. WebHigh-performance fibers made of ultra-high molecular weight polyethylene (UHMWPE) or aramid fibers have been widely used to weave ballistic-resistant fabrics.

Web2 de fev. de 2011 · A heavier bullet will have a better (higher) sectional density than a lighter bullet of the same caliber. For this reason, bullets that are lighter tend to have a lower ballistic coefficient than heavier bullets (assuming of course that the bullets have the same aerodynamic shape). 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 acceleration—the drag on the body is small in proportion to its mass.
