Carbon ThreeSixty, Leonardo, and the Nationwide Composites Centre have joined forces to create an all-composite helicopter wheel. The NATEP venture, which started on January 1, 2021, goals to make use of the group’s mixed talent units to create and manufacture these wheels utilizing carbon-fiber-reinforced plastic (CFRP) over the following 18 months.

As of now, aluminum or magnesium are sometimes used for helicopter wheels. Nonetheless, the venture goals to vary the narrative by including composites to the combination. The CFRP wheel has many advantages, comparable to enhanced mechanical properties with much less density than its metallic counterparts. The wheels are additionally being designed to be interchangeable with current wheels – permitting for retrofitting if desired. As well as, they will even provide a weight financial savings of roughly 40% over aluminum. Adrian Smith, R&T Portfolio Supply at Leonardo Helicopters UK notes that “composites are anticipated to avoid wasting round 1.5 kilograms over every 5-kilogram alloy wheel. This 6-kilogram weight-saving general represents virtually 1,000 gallons of gasoline saved over a typical 12,000-hour service life and equates to round 12 tons of CO2”.

The collaboration will characteristic the most recent manufacturing expertise comparable to tailor-made fiber placement (TFP), braiding, and out-of-autoclave (OOA) processes, permitting for higher repeatability and scalability.

In complete, the venture is anticipated to value roughly $340,000. Deliverables will embody 12 totally examined proof-of-concept wheels and a technique for design and manufacture.
