摘要

A simple approximation of the apex pressure differential is derived for single cell,natural shape balloons. For most present day balloons the approximation is valid up to at least tropopause heights. Use of the equation p = 0.93b2/3Wg1/3 (accurate to within 5per cent) should provide an easy method for both designers and operators. (Author)
