US 5,090,326 A · Lightweight training bomblet equipped with axially tensioned housing covers

Abstract

A lightweight training bomblet provided with a housing made of cardboard or plastic. Such training bomblet should be easily assembled and be able to withstand the high acceleration forces generated during transport into a target area. To prevent undue deformations of the bomblet housings made, for example, of cardboard, during air transport and the resulting premature ignition during ejection from a carrier projectile, both cardboard or plastic housing covers are connected with one another by means of a pre-tensioned connecting arrangement and their abutment faces are pressed against the end faces of a tubular housing shell, with the abutment faces of the housing covers possibly additionally containing a holding and sealing arrangement which is pressed into or against the end faces of the housing shell. Preferably the holding and sealing arrangement is composed of an annular blade member which is cylindrical on its exterior surface and conical on its interior surface, thus providing, in the assembled state of the bomblet, high stability of the tubular housing shell and a good sealing effect. The connecting arrangement for the housing covers may be composed of an axially disposed screw connection in which a delayed ignition charge is disposed in a space saving manner.

Dependent claims

A training bomblet comprising:

a tubular housing shell formed of one of cardboard and plastic;
first and second housing covers, each formed of one of cardboard and plastic, centered on and closing respective opposite ends of said tubular housing shell, said covers having respective abutment faces which contact respective end faces of said shell, with each said abutment face of said housing covers including a respective holding and sealing means which is pressed into a respective end face of said housing shell and comprises an annular blade member which has a cylindrical exterior surface extending substantially parallel to a longitudinal axis of said bomblet and a conical interior surface which tapers toward a cutting edge;
a signature charge disposed in said shell and fixed at both end faces thereof by said covers;
a delayed ignition charge accommodated by one of said housing covers;
and a pretensioned connecting means for connecting said covers together and for pressing said abutment faces against respective said end faces of said tubular housing shell.
