WebLower ballistic coefficient offers an optimal re-entry, wherein the vehicle decelerates higher up in the atmosphere thereby decreasing the imposed aerothermal loads. 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. BC can be expressed with … Ver mais General $${\displaystyle C_{\text{b,Physics}}={\frac {m}{C_{\text{d}}A}}={\frac {\rho \ell }{C_{\text{d}}}}}$$ where: • Cb,Physics, … Ver mais Most ballistic mathematical models and hence tables or software take for granted that one specific drag function correctly describes the drag and hence the flight characteristics of a … Ver mais • External ballistics - The behavior of a projectile in flight. • Trajectory of a projectile Ver mais Background In 1537, Niccolò Tartaglia performed test firing to determine the maximum angle and range for a shot.
