Tupolev is offering an upgrade and modernisation programme for its Tu-154. Rybinsk Motors, which makes the D-30KU engine powering the Tu-154M, has developed a modification which it claims reduces fuel consumption by 4-5%. The company is also developing a low-emission combustor, and a Stage 3 hushkit for the engine. Although it acknowledges that the silencer equipment adds weight and reduces economics, Rybinsk says that the kit will enable the maximum take-off weight and flap setting limitations to be removed.
