Mark G. Yonash is a notable inventor based in Derby, Kansas, who has made significant contributions to the field of aircraft manufacturing technology. With a total of 3 patents to his name, he has developed innovative solutions that enhance the efficiency and effectiveness of composite material lay-up processes.

Latest Patents

One of his latest patents is titled "Unidirectional, multi-head fiber placement." This invention involves an aircraft part manufacturing device designed for automated composite lay-up. The device features a mandrel tool with an interior surface that conforms to the outside mold line of the part to be manufactured. Surrounding the mandrel are one or more circular rings that rotate, supported by bearings in a bearing cradle. This design allows the mandrel to rotate concentrically with the circular rings, enabling multiple composite material delivery heads to simultaneously deliver material directly to the outside mold line on the interior mandrel surface while the mandrel is rotated.

Another significant patent by Yonash is "Automated composite lay-up to an internal fuselage mandrel." Similar to his previous invention, this device also includes a mandrel tool with an interior surface that conforms to the outside mold line of the part to be manufactured. The circular rings rotate, allowing a composite material delivery head to deliver material directly to the outside mold line on the interior mandrel surface while the mandrel is rotated. A cantilever-supported gantry beam supports the material delivery head, providing motion relative to the interior mandrel surface.
