Conceptual design issues of constructive schemes of turbopump units of aircraft engines

The paper analyzes the construction scheme products to a large extent determine the parameters of its technical excellence and reliability, as the concept of its design and conceptual issues related to the process of selecting the design concept stage to the product conceptual design. The features of this process on the basis of a systematic approach are illustrated by the example of the turbopump assembly-engine aircraft with a design scheme is determined by the parameters and the structural elements of the machine, engine and aircraft, for which the engine is designed. Emphasizes the need to address the structure and properties of the product. It is shown that the design of new technology products are on the way of dialectical contradictions between the growing scientific and technological needs and opportunities of the current generation of products. In order to generalize the analysis formulated principles for the selection of design schemes for product conceptual design stage.
