Abstract

Expressing the coefficient q, of the rate‐of‐ascent formula of the balloon (e.g. V = q F^1/2^/(W + F)^1/3^, where V is the rate of ascent of the balloon, W the weight of the balloon and F the free‐lift) in terms of the coefficient of aerodynamic resistance ΞΊ of the balloon, a curve of q as a function of the Reynolds number N is worked out. Introducing a ~ΞΊ~N^2^ – N curve, the value of q, appropriate to a balloon flight is obtained.
