A swashplate guide for use with a spherical bearing and which connects with an adjacent component includes a hollow cylindrical tube formed from a composite material. An exterior surface of the hollow cylindrical tube provides an engagement surface with the spherical bearing. A flange arranged at an end of the hollow cylindrical tube provides an interface with the adjacent component.

A shaft assembly includes one or more axially-arranged plies having a plurality of bundles of strands. Each strand is formed of a ultra-high modulus carbon fiber material. One or more strands of glass fiber are wrapped around each bundle of the plurality of bundles. A volume of resin injected into the one or more axially-arranged plies and the assembly is cured via a resin transfer molding process. A method of forming a shaft assembly includes arranging a plurality of strands of ultra-high modulus carbon fiber material into a plurality of bundles. Each bundle of the plurality of bundles is wrapped with one or more strands of glass fiber material. The plurality of bundles are arranged into one or more axially-extending plies at a mandrel. A volume of resin is injected into the plurality of bundles and is cured to form the shaft assembly.

A heater mat for a rotor blade includes a plurality of electrically conductive heater wires extending in a path along a span of the rotor blade and a plurality of yarn thread knitted to the plurality of heater wires, each of the yarn threads looping around at least one of the plurality of heater wires. A warp thread is positioned between adjacent heater wires and knitted to adjacent pairs of the yarn threads without looping around the plurality of heater wires, to maintain spacing between adjacent heater wires of the plurality of heater wires. An electrical current flowed through the plurality of heater wires inhibits ice accumulation on the rotor blade assembly.
