<p>The duct has outer and inner walls (60, 68) fixed to an end on an intermediate case (30) and connected to another end at an exhaust case (44). The inner wall has removable panels (72) fixed on a frame (70) that includes upstream and downstream annular structures (82, 84) and longitudinal elements to connect the structures. The outer wall includes openings (64) closed by the panels, which are removably fixed on a unitary and rigid support structure. The openings have dimensions permitting passage for the panels and assembling and disassembling of the panels on the frame. An independent claim is also included for a method for assembling a blowing pipe.</p> |
