GKN Aerospace (St. Louis, Mo., U.S.) has delivered a pair of thermoplastic composite (TPC), induction-welded ruddervators, and two compression-molded access panels manufactured from reused thermoplastic waste material, to Bell Helicopter (Ft. Worth, Texas, U.S.) for a demonstrator of the V-280 Valor military aircraft.

GKN Aerospace has designed and manufactured the complete thermoset composite V-Tail currently used on the Bell V-280 Valor. The new thermoplastic ruddervators — which are control surfaces for the V-tail aircraft — and access panels are technology demonstrators planned for flight testing on the aircraft this year. This will make the V-280 one of the first military aircraft flying with thermoplastic components, the company says.

“It is very exciting that our cutting-edge thermoplastic technology will be flight tested for the first time on the state-of-the-art V-280 Valor,” says John Pritchard, CEO of GKN Aerospace ASEA.

The two compression-molded access panels have been manufactured from recycled thermoplastic waste material from the two ruddervators and have been developed in a Dutch TPC-cycle research program led by Saxion University (Enschede, Netherlands). GKN Aerospace is a partner in the research program.

Use of thermoplastic composite technology on a military platform will reportedly open up opportunities for wider applications in the defense market, offering advantages in terms of weight, costs, production time and environmental impact. 

In addition to the demonstrator program, the GKN Aerospace global design team says it will support Bell with further design optimization of the V-Tail.
