Abstract
A regenerative circuit structure is built up by implementing the following steps in particular: PA1 an intermediate layer is made on a support core representing the inner profile of the structure; PA1 a series of channels regularly distributed around the core is made with the channels opening to face the intermediate layer, each of the channels being provided with a soluble insert; PA1 the support core is preheated and the body of the structure is made by thermal spraying under a vacuum; PA1 channels are machined in the body from the outside, and said channels are filled by means of soluble inserts; PA1 a closure layer is formed to close the channels in the body, and an outer envelope is formed by thermal spraying under a vacuum, after preheating; and PA1 all of the soluble inserts and the intermediate layer are eliminated.
