Willibald Wittich, Deceased

Title: Willibald Wittich: A Pioneer in Heat Exchanger Technology

Introduction

Willibald Wittich was a notable inventor known for his contributions to heat exchanger technology. He was based in Ottobrunn, Germany, and held a total of 3 patents during his career. His innovative work has had a lasting impact on the field of engineering, particularly in the design of combustion chambers for rocket engines.

Latest Patents

One of Wittich's significant patents is the "Cooling channel surface arrangement for a heat exchanger wall." This invention focuses on a wall construction used in regeneratively cooled combustion chambers for liquid-fueled rocket engines. The design features an inner wall with cooling channels that are spaced apart by webs. These channels are open on one surface of the inner wall, while an outer wall contacts the webs and forms a closure over the openings. The outer wall is constructed with an intermediate layer that is electro-deposited on the inner wall, providing a closure surface for the channels. The surfaces of the channels are coated with a layer of gold, enhancing their performance and durability.

Another notable patent is the "Method of producing shaped objects." This method involves forming shaped objects through a powder-metallurgical procedure. A dummy object made of a meltable material, such as wax, is prepared to match the desired shape. A self-supporting layer is electroformed around the dummy object, which is then melted away to create a hollow space. Metallic powder is filled into this cavity and subjected to hot isostatic pressing to form the final shaped object.

Career Highlights

Wittich's career included significant roles at Messerschmitt-Bolkow-Blohm GmbH and Messerschmitt-Bolkow-Blohm Gesellschaft mit beschränkter Haftung. His work at these companies allowed him to develop and refine his innovative ideas in engineering and technology.
