04 Dec 1970TL;DR: A filament reinforced gas turbine engine blade having a divergent root defined by a particular splay radius comprising oriented high modulus, high strength nonductile first reinforcing filaments embedded in a matrix and forming a radius of curvature greater than the splay diameter and no smaller than its working radius is defined in this paper.
Abstract: A filament reinforced gas turbine engine blade having a divergent root defined by a particular splay radius comprising oriented high modulus, high strength nonductile first reinforcing filaments embedded in a matrix and forming a radius of curvature greater than the splay radius and no smaller that its working radius, and oriented high strength ductile second reinforcing filaments embedded in a matrix and forming a radius of curvature which is equal to or less than the splay radius with no loss of strength therein.

TL;DR: In this article, local heat transfer coefficients and temperature distributions within the fluid for air flow around a 180° square-sectioned bend have been measured and the ratio of bend radius to hydraulic diameter of the duct is 3.35:1 and the flow entering the bend is sensibly fully developed.

TL;DR: In this article, the bend radius and orientation of the fiber in the bend considerably affect the single-polarisation operation of bow-tie fibres, and the effect of bend radius on the singlepolarization operation was investigated.
Abstract: Experimental results are presented which show how both bend radius and the orientation of the fibre in the bend considerably affect the single-polarisation operation of bow-tie fibres.

TL;DR: An aerogel composite can bend to at least 90° and a bending radius of less than ½ inch without any substantial fracture as discussed by the authors, provided that it is fully enclosed by an envelope and sealed at a reduced pressure.
Abstract: An insulating structure comprising an aerogel composite fully enclosed by an envelope and sealed at a reduced pressure, said aerogel composite comprising at least one metal oxide matrix and a fibrous material incorporated therein, and where said insulating structure can bend to at least 90° and a bending radius of less than ½ inch without any substantial fracture.

TL;DR: It is found that very low bend loss at small bend radius can be achieved with large d/Delta and best differential mode loss is achieved at large bend radius.
Abstract: Bend loss of the first three modes of leakage channel fibers with various designs are studied using finite element method. It is found that very low bend loss at small bend radius can be achieved with large d/Λ. It is also found that best differential mode loss is achieved at large bend radius. It is further found that 2nd order mode loss becomes 9.1 times of fundamental mode loss at small bend radius for the bend orientation where the bending plane crosses centers of two holes and independent of d/Λ. Bend loss dependence of bend orientations are also studied. Excellent agreement between experiment and simulation is obtained.
