Abstract : J. L. Ryhming concluded that the minimum-boom body for given bow-shock wave drag and maximum body thickness is also the minimum drag body due to the bow shock for a given maximum body thickness. It is shown that the above conclusion is only valid for asymptotic distances. The geometry of the minimum-boom body depends on the distance for which one wants to minimize the sonic boom. (Author)
