Latest Patents

Costeplane holds a patent for a "Progressive hot twisting apparatus for use in a process for manufacturing a hollow turbomachine blade." This apparatus is designed for manufacturing blades made from a titanium alloy of the TA6V type. The process involves a hot twisting step where an element of the blade is twisted progressively at temperatures exceeding 700°C. This is achieved through a series of bars that rotate around the twist axis, acting on collars fixed to the blade element. The distribution and number of collars are strategically determined to achieve the desired twist, ensuring a linear twist development between each collar. This innovation represents a significant advancement in the manufacturing of high-performance turbomachine components.
