摘要

Reflected pressures have been measured on a 2-dimensional wedge over the range of 0 to 90 degrees of incidence for shock waves of 13.8 and 34.5 kPa overpressure. The higher than normal pressures predicted by regular reflection theory in the range of angles just prior to the onset of Mach reflection are found to agree closely with theory. Reflected pressures for a small range of angles of shock incidence greater than those for which regular reflection is predicted are found to exceed the highest predicted regular reflection values. The pressure history scales as expected in time as a function of distance from the starting edge of the reflecting surface. Curves of reflected pressure versus angle of incidence are presented for the two incident shock levels. Curves of pressure versus distance-scaled times are presented which can be used to determine instantaneous wholse surface loads. (Author)
