I work at R-R in Derby, on repair and overhaul, on the 04 module, (hp system) and in the last 20 years the evolution of the 211 into the Trent has been great to watch.
The fancases are getting bigger, while the cores are getting smaller.Flamecans are now lined in ceramic tiles, hp turbine blades and guide vanes are also ceramic-covered on the gas path surfaces.The hp compressor drums are now 1-piece items on the -700,the blades located in circumfrential slots instead of dovetail slots,compared to a 524 B4 it`s a world away in terms of ease to build.
Weight saving, low emission and noise levels have all been achieved through re- designing nacelles, fan blades and exhaust features, anyone notice the rear nacelle on the T1000?.
XWB next, already completed it`s 1st run with success and over 1000 on order.
