To the Question of Optimizing Product Life Cycle STAGES

In given article the way of management of a life cycle of a product of aviation technics by optimization of stages of internal designing of aircrafts and minimization of risks of acceptance of key technical decisions at early stages of realisation of the project is considered. As an example of such optimization, the process of designing the nose part of a supersonic aircraft was chosen. On this example possibilities of essential reduction of terms and risks at the expense of working out and introduction of a complex technique of designing on complex criterion of the top level are visually shown. Introduction of the approach to the design of aircraft equipment described in the current work, in all directions of aircraft development will reduce the design cycles of fundamentally new products, significantly improve the accuracy of forecasting test results, and consequently minimize the risks of failure of the timing of government tests.
