Abstract

Calculation of additive drag at static conditions is usually not a problem simply because multiplying the drag coefficient by the dynamic pressure (which is zero) is always zero. However, in some computer codes, if the additive drag coefficient is determined by dividing the additive drag force by the dynamic pressure, a zero divide errorcan result at static conditions. This problem is eliminated if the drag coefficient at static conditions is determined independently of the dynamic pressure. This technical note describes how such an expression was derived from an existing additive drag coefficient equation.
