Abstract: A drive shaft which includes a first tube body having one or more first body channels defined through a wall thickness thereof. The one or more channels are configured to increase bending and/or axial flexibility of the first tube body while only allowing for a less than proportional reduction in torsional stiffness of the first tube body. A second tube body can be concentrically disposed relative to the first tube body and connected to the first tube body at a first end portion and a second end portion. The second tube body can include one or more second body channels defined through a wall thickness thereof. The one or more channels are configured to increase bending and/or axial flexibility of the second tube body while only allowing for a less than proportional reduction in torsional stiffness of the second tube body.

Abstract: A drive shaft has a central tubular portion formed of a polymer composite with imbedded fibers. It extends between a first end and a second end. The central tubular portion has an outer peripheral surface. There is at least one ring on the outer peripheral surface of the central tubular portion. A method of repairing a composite material tube includes the steps of (a) identifying a damaged area on a composite tube, and (b) placing a patch on a surface of the tube and over the damaged area.

Abstract: A flexible composite driveshaft is formed by modifying the shape of a preliminary composite driveshaft. A fiber tape is applied to a temporary mandrel using automated fiber placement to form a preliminary composite driveshaft having a flexible shaft element with an initial geometry. The temporary mandrel from the preliminary composite driveshaft is removed and the initial geometry of the flexible shaft element is modified to form the flexible composite driveshaft having a flexible shaft element with a final geometry.

Abstract: A process for forming a flexible composite driveshaft includes providing a mandrel having a rigid region and a compressible region, applying fiber tape to the mandrel using automated fiber placement with in-situ laser curing in the rigid region and without in-situ laser curing the compressible region, and compressing the fiber tape and compressible material in the compressible region to form diaphragms that extend radially outward to a diameter that is at least twice the size of a diameter of the composite driveshaft in the rigid region.

An inner shaft that is concentric with the outer shaft and has a second diameter that is configured to provide structural support to the outer shaft. A gap is located between an outer peripheral surface of the inner shaft and an inner peripheral surface of the outer shaft. The gap has a size from the outer peripheral surface to the inner peripheral surface that is at least as large as a largest ballistic projectile cross-section size that the aircraft is expected to encounter on an upcoming mission. A sleeve is located at least at a first end of the outer shaft and connects the outer shaft to the inner shaft.

Abstract: In accordance with at least one aspect of this disclosure, a composite shaft comprises a plurality of composite elements arranged about an axis to form a hollow cylindrical shaft extending along the axis between a first end of the shaft and a second end of the shaft. The plurality of composite elements incudes: a first group of the composite elements aligned parallel to the axis, a second group of the composite elements arranged about the axis offset by an angle α relative to the first group in a first direction, a third group of the composite elements arranged about the axis offset by an angle γ relative to the first group in a second direction opposite the first direction, wherein the third group is offset from the second group by an angle 2α, and a fourth group of the composite elements arranged about the axis offset by an angle θ.

Abstract: A flexible coupling includes a first flange and a second flange, wherein in a relaxed state the first flange and the second flange are each aligned along a longitudinal axis. A plurality of first coupling members extends from the first flange. Each first coupling member includes a first and second driving beam meeting at a first node to form a topologically triangular truss. A plurality of second coupling members extend from the second flange. Each second coupling member includes a first and second driven beam extending from the second flange and meeting at a second node to form a topologically triangular truss. The first node of each of the first coupling members is connected to the second node of a respective one of the second coupling members.
