Advanced Reentry Aeromechanics. Volume II. Aerodynamic Shattering of Ice Crystals in Hypersonic Flight

Abstract

A theoretical study of ice crystal/shock layer interaction has been carried out in order to assess the relative kinetic energy of an ice crystal upon impact with a hypersonic vehicle. A dynamic fracture criterion has been developed which predicts the size of the ice crystal fragments formed at the vehicle bow shock. An analysis of the ice crystal breakup predicts that the outer fragments continue to shatter and prevent the shock layer gas from penetrating the fragment cloud. The fragment cloud is then treated as a deformable fluid drop, and the reduced impact velocity due to lateral spreading is determined.
