Title: Terashi Isago: Innovator in Rocket Combustion Technology
Introduction
Terashi Isago is a prominent inventor based in Shibata, Japan. He has made significant contributions to the field of rocket technology, particularly in the design and manufacturing of rocket combustion chambers. With a total of 2 patents, his work focuses on enhancing the efficiency and performance of rocket engines.
Latest Patents
Isago's latest patents include innovative designs for rocket combustion chambers. One of his notable inventions is the "Rocket combustion chamber cooling wall of composite cooling type." This invention features a cooling wall designed to manage heat loads effectively. The throat portion, which experiences the highest heat load, is constructed from a porous material that utilizes a perspiring cooling action. Meanwhile, the other sections are cooled using conventional forced convection methods. This composite cooling system not only provides a high cooling effect but also minimizes pressure loss in the cooling passages, contributing to a lightweight and long-lasting engine.
Another significant patent is the "Method of manufacturing a rocket combustion chamber." This invention employs powder metallurgy to create a grooved cooling wall for liquid-propellant rocket combustion chambers. The inner cylinder of the cooling wall is designed with cooling grooves filled with a filler material, such as paraffin wax. After the filler is removed, the metal powder, which forms the outer cylinder, is compression-molded around the inner cylinder. The sintering process then joins the inner and outer cylinders, resulting in a robust and efficient cooling wall.
