摘要： A gas turbine engine impeller having a plurality of blades attached to a rotor disk and an integral, annular collar defining openings through which the blades extend which acts as a platform extending between the adjacent blades. The annular collar is formed as an integral, annular structure and may be formed from a composite material, or other material which is resistant to high temperatures and high centrifugal forces. The annular collar defines a plurality of openings to accommodate the blade portion of the plurality of blades and to enable the blades to extend radially outwardly from the collar. The openings may be formed in the annular collar when the collar itself is formed, or may be machined therein after the collar has been fabricated.

摘要： The two-dimensional adjustable nozzle according to the invention is a generally rectangularly shaped nozzle having a pair of opposite, fixed sidewalls defining the lateral boundaries of the nozzle and adjustable flap assemblies extending between the lateral walls and defining the upper and lower boundaries of the nozzle. The adjustable flap assemblies each have an interior flap and an exterior flap associated with a rocking lever which, in turn, is connected to an actuating mechanism. The actuating mechanism, which may be a jack screw, is located within the lateral sidewalls and is controlled by a rotatable cable. Rotation of the jack screw shaft which is connected to the rocking levers, causes the rocking levers to move in a direction generally transverse to the longitudinal axis of the nozzle to thereby adjust the angular positions of the interior and exterior flaps.

摘要： Disclosed is a method of manufacturing a composite material burner ring made wholly of a composite material. The burner ring is manufactured by winding a carbon or ceramic type refractory material about a toroidal form until a specific material thickness is obtained. The burner ring elements, such as radial arms, fastening clips or fuel feed tubes are then fastened onto the winding. Each of the elements may be formed in mirror-image halves and may be assembled onto the burner ring body in adjacent pairs, each one of the pairs facing in an opposite direction. The winding of the composite material is continued until a final thickness is obtained, thereby integrally attaching the burner ring elements to the burner ring body. The assembly is then subjected to a carbonization or ceramization head treating process. After this process, the burner ring body is cut along a plane extending generally perpendicular to the longitudinal axis of the toroidal form such that two burner ring assemblies having gutter-shaped cross-sections are formed when removed from the toroidal form.
摘要翻译： 公开了一种整体由复合材料制成的复合材料燃烧器环的制造方法。 燃烧器环通过绕环形形式缠绕碳或陶瓷型耐火材料制造，直到获得特定的材料厚度。 然后将燃烧器环元件，例如径向臂，紧固夹或燃料供给管固定到绕组上。 每个元件可以形成为镜像半部，并且可以相邻对组装在燃烧器环体上，每对中的每一个面向相反的方向。 复合材料的卷绕继续进行，直到获得最终厚度，从而将燃烧器环元件整体地附接到燃烧器环体上。 然后对该组件进行碳化或陶瓷化头处理工艺。 在该过程之后，沿着大致垂直于环形形状的纵向轴线延伸的平面切割燃烧器环体，使得当从环形形式去除时，形成具有沟槽状横截面的两个燃烧器环组件。
