Abstract
A hybrid inner fixed structure is disclosed. The inner fixed structure may have an inner fixed structure panel having an inner fixed structure panel surface and an inset panel having an inset panel surface disposed in at least partial contact with a first portion of the inner fixed structure panel surface. In this manner, a hybrid inner fixed structure may be designed to be both lightweight and heat tolerant.
Claims14
A hybrid inner fixed structure comprising:
- an inner fixed structure panel having an inner fixed structure panel surface;
- an inset panel having an inset panel surface disposed in at least partial contact with a first portion of the inner fixed structure panel surface;
- and
- wherein the first portion of the inner fixed structure panel comprises a flange defined by a flange attachment boundary and whereby the inset panel mounts flush with the inner fixed structure panel,
- wherein the inner fixed structure panel comprises:
- an upper bifurcation;
- a center member comprising an upper boundary and a lower boundary;
- and
- a lower bifurcation,
- wherein the upper bifurcation unites with the center member at the upper boundary, wherein the lower bifurcation unites with the center member at the lower boundary, wherein the upper bifurcation extends substantially normal to the surface of the center member at the upper boundary,
- wherein the lower bifurcation extends substantially normal to the surface of the center member at the lower boundary, and
- wherein at least one of the upper bifurcation, the center member, and the lower bifurcation is disposed in at least partial contact with the first portion of the inner fixed structure panel surface.
