ABSTRACT:
Disclosed is a composite metal article and embodiment of a practice bomb used in the training of pilots. It comprises a body and fin structure having a predetermined center of gravity and aerodynamic design. The composite structure provides both the aerodynamic properties and physical characteristics equivalent to the prior art devices but with significant reduced costs and additionally manufacture which results in significantly less air pollution in the casting process. The process involves casting the body within a thin walled shell which becomes the outer surface of the composite body.
