Abstract
A transition duct arrangement for feeding combustion gases under pressure from a number (e.g. 4), of combustion chamber(s) arranged around the turbine into the annular passage containing the turbine blade structure. Each combustion chamber (5) has a transition duct section comprising a short length of the cylindrical combustion chamber walls (9 inner and 11 outer) developing into a section of annular duct (25 inner and 27 outer). The four transition duct sections make up a complete annulus but have to be clamped to the nozzle guide vane (85 FIG. 7 ) structure. The invention provides a means for combining the clamping and sealing of the transition sections efficiently and effectively.
