More Book Details

Description of the Book:

At vertical water entry of a missile the splash varies greatly with nose shape and thus modifies the cavity development. Accordingly, the relations reported earlier between cavities formed by different noses at oblique entry, cannot be applied to vertical entry. An ‘Ideal Cavity’ is defined as that portion of the cavity near the generating nose, which has not been appreciably affected by such influences as gravity or the difference between ambient pressure and the pressure in the cavity. It is shown that all such cavity portions are geometrically similar, with a size proportional to the square root of the drag force at a given speed
