PROBLEM TO BE SOLVED: To provide a honeycomb cell type sandwich panel cooled or vented through a cell. SOLUTION: This panel, using any of a differential pressure in a panel side surface or along the panel, in forced ventilation by a vent flow through a honeycomb cell opening a hole of the panel, can obtain an advantage. Two outer walls 61E, 61I relating to many honeycomb cells 65, 67, in order to circulate air by a different method through the honeycomb cell which must be vented, have a hole 63 in the first wall 61E, hole 66 in the second wall 61I and several holes 68 in an internal partition 62. The cell is used in all the panels required for cooling, and particularly in a wall rotated between hot/cold flows of a gas turbine engine. |
