Abstract
Abstract
The aim of the investigation was to experimentally discuss effects of viscosity and launch pressure on variations of the maximum impact acceleration in cross media water-entry process. For different launch pressures, they reflected effects of motion peculiarity. They were 2.5MPa, 2.75MPa, and 3.0MPa. Variations of viscosity explained influences of property of operating environment. Via the change of lithium bromide solution mass fraction, various viscosities were got. The mass fractions employed were 1%, 2%, and 3%. Results indicated that the maximum impact acceleration grew steadily with the increment of lithium bromide solution viscosity. When launch pressure grew, the maximum impact acceleration increased gradually. Comprehensively, effect degree of viscosity was more intense than that of the launch pressure.
