US Patent:

44818580, Nov 13, 1984

Filed:

Mar 28, 1983

Appl. No.:

6/479659

Inventors:

Leonard W. Price - Marina Del Rey CA

Assignee:

Hughes Helicopters, Inc. - Culver City CA

International Classification:

F41D 500
F41D 1006

US Classification:

89 11

Abstract:

A single barrel externally powered gun includes a feed mechanism, a bolt assembly, a bolt control assembly and a power transmission system. The bolt control assembly is in the form of a chain drive unit driven continuously along a predetermined path of travel which defines the timing and sequence of loading, ramming, firing and ejecting. The chain drive assembly controls the reciprocating motion of the bolt assembly relative to a fixed non-rotating and non-reciprocating barrel, the bolt being stationary in the firing and loading sequences. The feed mechanism which continuously advances rounds is integrated to the intermittent motion of the bolt by a Geneva wheel mechanism, as the bolt assembly reaches the proper position in its rearward movement. Bolt locking, firing and unlocking are all controlled, and carried on while the chain drive assembly is continuously moving. In another form, a parallel index drive assembly may be used in place of a Geneva wheel mechanism with resultant simplification of the overall gun structure.
