Abstract
The invention disclosed relates to a Modular Practice Bomb which closely simulates the horizontal range of a wide variety of actual bombs, within acceptable limits, while maintaining flight stability. By suitable modification of a standard configuration practice bomb, its coefficient of drag may be varied in order to match the ballistic coefficient of the Modular Practice Bomb with that of a predetermined actual bomb. This is conveniently done by attaching an appropriate tail-mounted module.

In a practice bomb for closely simulating the horizontal range of an actual bomb within acceptable limits under various release conditions, said practice bomb comprising:
- (a) a nose section,
- (b) a cylindrical central body section, and
- (c) a tail section including a plurality of stabilizing fins spaced about the longitudinal axis of the body, the improvement comprising providing a standard configuration Modular Practice Bomb of fixed effective diameter and substantially constant weight, and including means for varying the coefficient of drag of the Modular Practice Bomb while maintaining flight stability, said means comprising a detachable tail module mounted on said tail section and a rigid frusto-conical configuration co-axial with said longitudinal axis and between said fins.
A method of closely simulating the horizontal range of a wide variety of actual bombs within acceptable limits under various release conditions, comprising providing a standard configuration Modular Practice Bomb of fixed effective diameter and substantially constant weight, and varying the coefficient of drag of the Modular Practice Bomb to provide a close match of the ballistic coefficient and horizontal range of the Modular Practice Bomb with that of a predetermined actual bomb, while maintaining flight stability, within a specified release envelope by calculating the drag coefficient of said practice bomb required to match the drag coefficient of said actual bomb and increasing the drag coefficient of said practice bomb to said calculated value by providing the practice bomb with a detachable tail-mounted module of an appropriate configuration.
