Preliminary Study of a Recoil Mechanism Using Coulomb Friction.
Abstract
This report is an investigation of the possible use of Coulomb friction for recoil energy dissipation in a friction recoil mechanism (FRM) for large bore cannon. Basic concepts and experimental friction material characteristics contributing to FRM functional and logistic feasibility are presented. From practical considerations, a recoil mechanism should be a relatively passive system incorporating automatic or intrinsic actuation prior to or at firing, should be self-contained, and should be tolerant of or compensate for variations in recoil travel. From a logistics standpoint, a recoil mechanism should demonstrate an extended in-service life, allow simple field servicing and repair, and permit long-term storage with rapid field recommission. The ultimate consideration of such a recoil system is its reliability over repeated firings. A single failure may cause catastrophic equipment damage and/or personnel injury. The comparative simplicity of conceptualized FRM hardware should allow superior performance in all three logistic areas stated above. FRM live/service interval would be a calculable function of the friction material wear rate and not a statistical estimate of effective seal life before failure. The simplicity and mechanical nature of FRM design should permit less complex service procedures.
