 Project objective

This proposal is aimed at developing novel, super hard, non-lubricated air cooled bearings that would give a step change in minimizing the engine oil system and its complexity. An SFC gain of 0.1 to 0.3% is anticipated as a result of this project. The project aims to achieve this by developing air cooled bearings using synthetic diamond. The novelty is in the surface finish of diamond rolling elements and mating raceways which can be improved substantially relative to today’s metallic bearing materials such that heat generation and frictional wear is minimized. Diamond offers superior thermal properties enabling thermal gradients and running clearances to be optimized.

This proposal aims to reduce oil system cost, weight and complexity by exploiting the properties of synthetic diamond material in the design and manufacture of novel bearings. The basic premise is that the surface finish of diamond rolling elements and mating raceways can be improved substantially relative to today’s metallic bearing materials such that heat generation and frictional wear is minimized. Diamond’s superior thermal properties enable thermal gradients and running clearances to be optimized using air rather than oil as the cooling medium.

The partners have assembled a consortium that has bearings expertise, capability in the manufacture, forming and metrology of synthetic diamond materials, and a proven track record in the design and evaluation of gas turbine air cooling schemes, with test facilities that will allow for friction and integrity proving from technology readiness level (TRL) 2 to 4. The consortium believe that all aspects of demonstration and industrialization can be successfully delivered with the work packages that have been assembled to TRL 4, with a final design complete for TRL 5 endurance tests.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "DEBRA" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
