In connection with investigations being conducted on the basic factors involved in the breakup of liquids and the formation of aerosols, the breakup of drops is being studied under conditions that occur in spray from high-speed aircraft and in explosive dissemination. This is the first report of a series on drop breakup studies. In this report the apparatus built for these studies is described. Initially a blast gun was used, and for reasons discussed herein, a shock tube was used in the later phases. Subsequent reports will describe the experimental results in detail.
