Research abstract

Triton Systems, Inc proposes to develop a Polymer Matrix Composite (PMC) drive shaft for the lift fan of the Joint Strike Fighter (JSF) Short Take-Off Vertical Landing (STOVL) system. The Composite Lift Fan Drive Shaft (CLFDS) will provide increased fatigue life and a significant weight reduction over the current titanium design. The PMC shaft will meet or exceed the requirements of the US Navy by utilizing the low density, high strength and directional mechanical property control of Carbon Fiber Reinforced Plastic (CFRP), to tailor the performance of the shaft to the specific operational loads. The high stiffness of CFRP can allow the shaft to run longer unsupported distances, reducing the number of bearings required for the system and thereby reducing the weight of the overall drive system. CFRP also has excellent damping capabilities, which can help minimize wear at bearing supports.
