Abstract
A light weight field howitzer includes a barrel which is supported by a cradle constructed from hollow members and which is pivotally mounted about a trunnion bearing secured to a chassis. The trunnion bearing lies on the barrel axis and is positioned beyond the limit of maximum recoil of the barrel. Front stabilisers and rear trail support legs are provided to spread the load of the howitzer and spades are rigidly secured to the chassis. The howitzer includes a single hydraulic accumulator arrangement constituting a combined recoil buffer and recuperator system. A barrel elevating means is provided comprising a geared manual means assisted by a precompressed gas system.
Claims1
A field howitzer comprising:
- i) a chassis,
- ii) a howitzer barrel mounted on the chassis so as to be displaceable from a first to a second position with respect to the chassis, as a consequence of recoil on firing, wherein the barrel is supported in a trunnion support structure by means of a cradle and the cradle is constructed from hollow members,
- iii) a recoil buffer system to absorb the energy of recoil as the barrel is displaced on firing, and
- iv) a recuperator system to return the displaced barrel from the second position to the first position, said recoil buffer system and said recuperator system being combined and utilizing a single hydraulic accumulator arrangement, the space inside said hollow members being used, wholly, or in part, to provide the volume for compressed inert gas forming part of said hydraulic accumulator arrangement.
