Перспективы выращивания ракетного сопла с помощью технологии прямого лазерного выращивания

Abstract

Modern rocket engine manufacturing demands innovative approaches to enhance efficiency, reliability, and cost-effectiveness. One promising solution is directed energy deposition (DED), an additive technology that enables the creation of complex geometries, such as bimetallic nozzles for liquid rocket engines, without traditional machining. DED allows for monolithic designs with integrated cooling channels, improving structural integrity and reducing failure risks under extreme thermal and mechanical loads. However, challenges remain, including controlling wall thickness, minimizing thermal distortion, optimizing material selection, and ensuring uniform microstructure and mechanical properties.
