Technically, ballistic coefficient is a numerical expression of a bullet’s aerodynamic properties, but most shooters look at it as just a number you enter into a ballistic calculator to see how ...

Now for some new stuff. First, don't let the term "aerodynamic drag coefficient" worry you. As in many cases where some sort of scientific methods are applied in the solution of engineering ...

These improvements have led to record levels of aerodynamic coefficients, which represent the dimensionless quantity used to quantify the resistance of an object in the air. The results were ...

The company is confident that when results come in, the Aptera will have the lowest aerodynamic drag coefficient of any production passenger car. Pininfarina’s wind tunnel was opened in 1972 ...
