DESIGN OF CARBON COMPOSITE DRIVESHAFT FOR PROPULSION SYSTEM
In our work we focused on design of lightweight drive shaft for connection of piston engine with axial flow fan. This shaft has got the following design criterions. Obvious requirement is the sufficient strength and wall stability to withstand torsional moment of 500 Nm which is estimated to be the peak one. Low weight is important for the propulsion system and aircraft overall weight. Bending stiffness high enough to allow the shaft to work in supercritical regime, but torsional stiffness low enough to allow the use of lighter shaft couplings are required. All these requirements can be fulfilled when composite material is used. For our application the hybrid construction is chosen, where flanges are made of Al-alloy and central cylindrical part is made of carbon fiber reinforced epoxy resin. Connections between composite and metallic parts are accomplished using epoxy adhesive system. Two different versions of composite shafts were produced to compare properties of them. Analytical solution of both shafts was done using classical lamination theory with the Pucks failure criterion. Finite element analysis of the cylindrical shell and of the adhesive bond was also done. Both analytical methods were compared with experimental results. This shaft is expected to be more useful for propulsion system than previously designed metallic version.
