Abstract

A liquid rocket engine contains a vast number of pipelines. The present article describes some of the features with respect to the pipelines fabrication, introduces the main factors influencing the mismatches during the engine assembly, proposes an approach to the pipelines fabrication based on the application of the advanced design, calculation, fabrication and inspection methods based on the 3D geometrical model of an object. The existing technology of the assembly provides for the manufacture of the engine layout, the reference design of the templates. Manufactured pipeline in accordance with the standard for each specific instance of the engine requires adjustment. The exclusion of modifications and adjustments during assembly requires the use of modern methods of design, production and control based on the use of the model-oriented approach. Including calculation mathematical modeling of all processes occurring during the manufacture and assembly of pipelines.
