The proposed project will develop an advanced control system (software and related hardware) and adapt this control system to a well developed and commercially available honing machine. The resultant system will be capable of producing controlled inside cylinder geometries with controlled taper and… More

The Integrated Surface Treatment System (ISTS) Plasma Spray CNC Workcell was originally designed to repair/refurbish a broad range of common worn parts so that they could be returned to service with a minimum of specialized operator skill or ancillary tooling. The concept holds great promise for… More

"Proposed work utilizes three existing fourth-generation modules of the cylinder kit model which applied to improving oil consumption, blowby and general engine life in gasoline and diesel engines for over thirty years. When completed, the proposed Phase 1work will:,h Link the three independent… More

"The objective of this project is to develop an expansion chamber/exhaust muffler system which will optimize the fuel economy/power density of small two-cycle compression engines while simultaneously providing 16 db or greater noise reduction.State-of-the-art validated computer models will be… More

The objective of this program is to research, formulate, and test high-temperature lubricants, materials, and modified cylinder systems optimized dimensionally for high-temperature operation. The lubricants, related materials, and system design are tooperate at a top ring reversal temperature of… More

When completed, the work outlined in this Phase II proposal will provide a cylinder kit model that can be utilized to: (1) predict wear rates for a range of currently utilized ring/liner material tribological couples; (2) consider the effect of third-body abrasives on wear rate (including abrasives… More

Phase II work focuses on developing an improved high-temperature engine lubricant base stock which will have acceptable vaporization rate and deposits at 875 deg F top ring/liner temperature. Actual lubricating film between the ring face and cylinder liner will be produced by use of a dry-film… More

The technology resulting from this effort will provide a comprehensive thermomechanical/ impact wear model. This integrated model will consider the developed thermal energy due to sliding friction and impact loading of the wear surface. In addition to the development of the theoretical model, a… More

The technology resulting from this effort will provide a theoretical wear model which, although focused on predicting slipper surface wear associated with Air Force high-speed sleds, can be utilized with appropriate input modifications to predict wear in a range of mechanical devices where… More

Successful completion of the proposed Phase I work outlined and follow-on Phase II work will provide a system to rank existing materials and coatings for severe wear applications. In addition, the ranking system can be utilized to identify desirable properties in new materials and/or coatings that… More

ABSTRACT: The proposal outlines work and time tables associated with finalizing the development of wear model concepts developed in Phase I work to predict the wear of two materials sliding with respect to each other while being subjected to high velocities and/or high pressures. In parallel with… More
