MECHANICAL DESIGN AND DEVELOPMENT OF THE RB211 DRY LOW EMISSIONS ENGINE
暂无分享,去创建一个
To meet current and proposed worldwide emissions regulations without recourse to steam or water injection, the Industrial RB211 is being upgraded with a premix lean burn series staged combustion system. To incorporate this system a reverse flow cannular concept was adopted. This design retains the inherent proven modular construction and is suitable for retrofit.This paper discusses the mechanical design analysis undertaken to ensure integration of the chosen solution into the RB211. Theoretical studies, combustion laboratory tests, aerodynamic scale and full size laboratory tests, together with extensive computer modelling were used to ensure the timely achievement of this design study.To verify the design analyses a detailed full power test programme is in place, which is to be followed by field trials with a pre-production engine during 1993.Copyright © 1993 by ASME
