专利汇可以提供Walls of combustion chambers专利检索，专利查询，专利分析的服务。并且A combustion chamber mounted in a flow of air at high pressure and the wall of which is provided with dilution holes located in the path of a cooling air film derived from the said flow through holes provided at a substantially truncated junction connecting an upstream wall element with a downstream wall element offset relative to the upstream element towards the outside of the chamber, wherein the upstream wall element is extended rearwardly of this junction by means of a tongue substantially parallel to the rear element, and wherein this junction has an inclination between 15* and 25* , preferably about 20* , the holes are arranged in zig-zag very near the upstream element so as to provide in the downstream direction a divergent portion of unperforated wall of substantial length, and the dilution holes are surrounded by flanges projecting into the combustion chamber.，下面是Walls of combustion chambers专利的具体信息内容。

权利要求

1. A combustion chamber operable in a flow of high pressure air, having an outer wall extending generally longitudinally in the flow of air and comprising an upstream wall section, a downstream wall section offset radially outward of the chamber relative to said upstream section, and an outwardly flaring wall section connecting said upstream and downstream sections and having an inclination angle in the range of about 15* to 25* relative to said upstream section, said outwardly flaring section comprising an upstream portion penetrated by a multiplicity of apertures arranged in staggered relation and an imperforate downstream portion of substantial length; said upstream wall section including an extension projecting substantially parallel to the downstream wall section and extending longitudinallY beyond the outwardly flaring wall section to form therewith an unperforated divergent passage of substantial length for cooling air entering through said multiplicity of apertures and flowing as a thin layer along the inner surface of said outer wall; said downstream wall section having flange-rimmed holes therein for inflow of dilution air to the combustion chamber, said flanges projecting interiorly of said chamber.

2. A combustion chamber according to claim 1, wherein the outwardly flaring wall section has an inclination angle of approximately 20*.

3. A combustion chamber according to claim 1, wherein the length of said flanges at least substantially equals the extent of the radial offset of said downstream wall section.

4. A combustion chamber according to claim 1, wherein the dilution holes are oblong, with their long dimension in the longitudinal direction of flow of the air film.

5. A combustion chamber according to claim 1, wherein the dilution holes comprise large holes alternating over the periphery of the wall with smaller holes.
