Abstract
A blocker door assembly for use in a gas turbine includes a panel, a core integrally formed with the panel, and a plurality of mounting structures extending from at least one of the panel and the core. The plurality of mounting structures are integrally formed with the core and the panel such that the panel, the core, and the mounting structures are co-molded from a thermoplastic material.
Claims19
A blocker door assembly for use in a gas turbine engine, the blocker door assembly comprising:
- a panel;
- a core comprising:
- a plurality of cells formed from a first wall having a first thickness and a second wall having a second thickness different from the first thickness, each cell of the plurality of cells defining a single cavity therein;
- and
- a plurality of stiffening ribs, each stiffening rib traversing more than one cell of the plurality of cells;
- and
- a plurality of mounting structures extending from at least one of the panel and the core, wherein the plurality of mounting structures are integrally formed with the core and the panel such that the panel, the core, and the mounting structures are co-molded from a thermoplastic material.
